Definitions
- the present disclosure relates to the treatment of chronic pain, osteoarthritis, inflammatory and immune disorders.
- Chronic pain is the number one reason why people seek medical advice in modern medicine. In spite of its multiple causes, chronic pain is accompanied by a cascade of biochemical reactions in the brain, spinal cord, dorsal root ganglia and peripheral nerves leading to neuroinflammation and neurodegeneration.
- neuropathic pain An example of chronic pain is neuropathic pain, which is often described as a shooting or burning pain. This type of pain can be unrelenting and severe, and often results from nerve damage or a malfunctioning nervous system.
- Neuropathic pain has multiple causes including amputation, chemotherapy, diabetes, HIV infection, multiple myeloma, multiple sclerosis, nerve or spinal cord compression from herniated discs or from arthritis in the spine, shingles, spine surgery, and other. Neuropathic pain also occurs with no obvious cause.
- neuropathic pain often responds poorly to standard pain treatments and occasionally may get worse instead of better over time. For some people, it can lead to serious disability.
- OA osteoarthritis
- OA is the most common joint disorder; the majority of individuals over the age of 65 have radiographic and/or clinical evidence of OA. The most frequently affected sites are the hands, knees, hips, and spine. OA symptoms include chronic pain, significant functional impairment, stiffness, and loss of mobility.
- the synovial tissue and cartilage produce pro-inflammatory cytokines, that induce chronic pain, inflammation and cartilage breakdown.
- cytokines such as Interleukin-4 (IL4), IL10 and IL13 and others, have potential in the treatment of chronic pain, inflammatory diseases, immune disorders, and other conditions.
- cytokines as stand-alone drugs have limited therapeutic effects in chronic pain, immune, inflammatory and other biologic processes, and clinical application of these molecules for inflammatory and immune diseases has been disappointing.
- IL4 interleukin-4
- IL27 IL10
- IL13 regulatory cytokine therapy
- the inventors developed a novel therapeutic approach, which relates to induction of unique signaling of cells by crosslinking of the receptors of two different cytokines. This unique signaling is neither induced by individual cytokines, nor by the combination of cytokines.
- Compounds of the disclosure cluster or crosslink the IL4 receptor and a cytokine receptor, and surprisingly, elicit unique responses in the nervous system, including unique signaling and gene expression profiles.
- the signaling and gene expression profiles generated IL4-cytokine fusion proteins of the disclosure are distinct from those observed in response to the combination of IL4 and the cytokine, and contribute to the superior therapeutic effects over the combination of the component parts.
- Bringing a receptor binding moiety corresponding to a first cytokine and a receptor binding moiety corresponding to a second cytokine together to induce unique signaling can be done with various constructs, such as with a bispecific antibody or a fusion protein.
- the approach according to the present disclosure i.e., to apply cross-linking of at least two or three, preferably two receptors chosen from the group consisting of IL4R, IL10R, IL13R, IL27R, IL33R, TGF ⁇ 1R, and TGF ⁇ 2R by incorporating two or more moieties that bind to said receptors, into one molecule, for example a bispecific antibody, provides a unique treatment for chronic pain, neuro-inflammatory and neuro-degenerative diseases, and inflammatory and immune disorders.
- the compounds disclosed herein, such as bispecific antibodies have much better manufacturability, pharmacokinetic and safety profiles than cytokine-based drugs.
- the first cytokine can be IL4 and the second cytokine may be IL10 or IL13, and the resulting fusion protein can be an IL4-10 fusion protein or an IL4/13 fusion protein, respectively.
- Administration of the resulting receptor-crosslinking agent for example a bispecific antibody against IL4-receptor (IL4R) and IL10-receptor (IL10R) or IL13-receptor (IL13R), may completely resolve chronic pain, reduce neuro-inflammation and protect against neurodegeneration in a human or animal subject, whilst administration of a combination of the individual cytokines IL4 and IL10 or IL13 cannot.
- IL4/IL10 fusion protein Previously, the inventors have reported on the therapeutic effects of the IL4/IL10 fusion protein (N Eijkelkamp et al., J Neuroscience, 2016, 36 (28) 7353-7363). The inventors have now unraveled the mechanisms of action underlying the therapeutic application of the IL4-10 fusion protein according to the prior art, and found that the IL4-10 fusion protein surprisingly, contrary to the combination of IL4 and IL10, promoted clustering of the IL4 receptor (IL4R) and IL10 receptor (IL10R) on sensory neurons, which in turn promotes unique signaling pathways and gene expression profiles that can lead to a full resolution of persistent pain.
- IL4R IL4 receptor
- IL10R IL10 receptor
- an IL4-13 fusion protein induces a unique protection of neurons against the damaging effects of chemotherapeutic drugs in vitro as well as in vivo, which was dependent on cross-linking of IL4R and IL13R, as the combination of wild-type IL4 and wild-type IL13 does not provide such protection.

- wild type refers to a cytokine with an amino acid sequence that is naturally occurring and encoded by a germline genome of a given species.
- a species can have one wild type sequence, or two or more wild type sequences (for example, with one canonical wild type sequence and one or more non-canonical wild type sequences).
- a wild type cytokine sequence can include a sequence that is truncated at the N and/or C terminus relative to the sequence encoded by an open reading frame.
- a wild type cytokine sequence can be a mature form of a cytokine that has been processed to remove N-terminal and/or C-terminal residues.
- a wild type cytokine can lack a signal peptide or can include a signal peptide (e.g., a signal peptide can be added to the N-terminus of the wild type cytokine).
- the term “derivative” refers to a cytokine with an amino acid sequence that differs from a wild type sequence by one or more amino acids, for example, containing one or more amino acid insertions, deletions, or substitutions relative to a wild type sequence.
- a cytokine derivative binds to at least one subunit of the corresponding native receptor for the wild type cytokine and elicits signaling and/or cytokine activity.

- a monoclonal (full) antibody comprises two light chains and two heavy chains, each comprising three CDRs, and has a total of 12 CDRs.
- a CDR region is a variable sequence involved in the physical binding of the antibody to its antigen.

- Such an exchange of CDR sequences is known as humanization.
- the compound, immunoglobulin molecule, or first and/or second binding moiety as provided by the disclosure may be humanized.
- the first binding moiety, second binding moiety and/or linker according to the present disclosure preferably specifically binds to its respective target.

- Single domain antibodies may be derived from any species including mouse, human, camel, llama, goat, rabbit, and bovine.
- naturally occurring VHH molecules can be derived from Camelidae species, for example in camel, dromedary, alpaca and guanaco.
- Single domain antibody is able to bind selectively to a specific target.
- Single domain antibodies contain only the variable domain of an immunoglobulin chain having CDR1, CDR2 and CDR3 and framework regions. With a molecular weight of only about 12-15 kDa, single domain antibodies are much smaller than regular antibodies (150-160 kDa) which are composed of at least two heavy chains and two light chains.
- regular antibodies 150-160 kDa
- the format of a single domain antibody has the advantage of less sterical hindering when bound to its target and may bind to epitopes not accessible to regular antibodies. This is both advantageous for the specific blocking and cross-linking properties as aimed for in the present disclosure.
- One other advantage may be that in the case of an allogenic source, single domain antibodies may be less immunogenic in other species than (full) monoclonal antibodies.

- the present invention discloses that unique signalling of intracellular processes is induced by crosslinking of receptors for these regulatory cytokines and that this unique signalling in cells in the dorsal root ganglia and the dorsal horn of the spinal cord results in an unprecedented analgesic effect.
- the present invention provides several compounds that can be used to crosslink regulatory cytokine receptors to induce such a unique cell signalling, which can be used as a medicament to treat chronic pain, and neuro-inflammatory and neurodegenerative conditions.
- These compounds include genetically engineered bispecific antibody that binds to two different receptors for regulatory cytokines, such as the IL4 receptor (IL4R) and the IL10 receptor (IL10R), or the IL4R and the IL13 receptor (IL13R).
- IL4R IL4 receptor
- IL10R IL10 receptor
- IL13R IL13 receptor
- Such bispecific antibodies have potent analgesic effects—surprisingly they inhibit chronic pain more effectively than the mere sum of the combination of the two cytokine moieties.
- injection of the anti-IL4R-IL10R bispecific antibody or anti-IL4R-IL13R bispecific antibody may completely resolve chronic pain in animal models.
- the inventors analysed the potency and mechanisms of a fusion protein that binds to both IL4R and IL13R and which has superior analgesic activity compared to the combination of wild-type IL4 and IL10.
- the inventors looked at the way in which cross-linking of IL4R and IL10R may transduce signals to the sensory nervous system.

- Example 1 Expression of Receptors for Regulatory Cytokines by Sensory Neurons and Glial Cells in the Dorsal Ganglia and Spinal Cord
- RNAseq data of receptors for IL10, IL4, IL13, and TGF ⁇ 1/2 in the dorsal root ganglia and spinal cord were extracted from the data base by Ray et al. (Pain 2018; 159:1325-1345) as available on www_utdallas.edu/bbs/painneurosciencelab/sensoryomics/drgtxome/?go.
- RNA sequencing revealed expression of receptors for IL10, IL4, IL33, TGF ⁇ 1 and TGF ⁇ 2 in the dorsal root ganglia and spinal cord of human and mouse ( FIG. 1 ; data are expressed as transcripts per million).
- IL4R ⁇ IL4R
- IL10R ⁇ IL10R ⁇
- Intrathecal administration is a well-known method to deliver drugs and other compounds in the direct environment of cells in the dorsal root ganglion and spinal cord.
- the inventors used intrathecal administration of antisense oligodeoxynucleotides (asODN) targeting IL4R ⁇ mRNA.
- asODN antisense oligodeoxynucleotides
- Three daily intrathecal injections of IL4R ⁇ asODN significantly reduced IL4R ⁇ mRNA and protein expression in the DRG by ⁇ 70% compared to mismatched (mm) ODN-treated animals ( FIG. 2B ).
- IL4-10 fusion protein was used to cross-link IL4R and IL10R.
- cross linking IL4R and IL10R may not completely abolish ability to detect sensory stimuli, but rather normalizes aberrant pain sensation.
- IL4R ⁇ knockdown in the DRG markedly reduced the analgesic effect of the IL4R-IL10R cross-linking compound compared to animals treated with mmODN ( FIGS. 2C and 2D ). Knockdown of IL4R ⁇ during established carrageenan-induced hyperalgesia did not affect the magnitude of mechanical hypersensitivity.
- Nav1.8+ sensory neurons mediate inflammatory pain (Abrahamsen et al. Science. 2008 Aug. 1; 321(5889):702-5).
- IL10R ⁇ was selectively ablated in Nav1.8+ neurons ( FIG. 2E ).
- the course of carrageenan-induced persistent inflammatory hyperalgesia was indistinguishable between wild-type and Nav1.8-IL10R ⁇ / ⁇ animals.
- Intrathecal injection of the IL4R-IL10R crosslinking compound (1 ⁇ g) at day 6 after induction of inflammatory pain attenuated thermal and mechanical hyperalgesia in wild type animals ( FIGS. 2F and 2G ).
- deletion of IL10R ⁇ in Nav1.8+ nociceptors partially ablated the analgesic effect of the IL4R-IL10R cross-linking compound ( FIGS. 2F and 2G ), indicating that nociceptor IL10R ⁇ may be required in part for the pain inhibiting effects of IL4R-IL10R cross-linking compound.
- both receptors are required for full analgesic effect of cross-linking IL4R and IL10R
- the inventors next considered if ablation of both receptors in sensory neurons would completely prevent the analgesic actions of the IL4R-IL10R cross-linking compound.
- IL4R expression was knocked down in Nav1.8-IL10R ⁇ / ⁇ mice with intrathecal IL4R ⁇ asODN injections. Knockdown of both IL4R ⁇ and IL10R ⁇ itself does not affect the course of persistent inflammatory pain.
- knockdown of both IL4R ⁇ and IL10R ⁇ expression in the DRGs completely prevented resolution of pain by the IL4R-IL10R cross-linking compound ( FIGS. 3A-D ).
- c-Fos expression can be used as a proxy of spinal neuronal activation in the dorsal horn of the spinal cord.
- the number of c-Fos positive neurons in the superficial layers of the dorsal horn was significantly increased compared to naive animals ( FIG. 3C ).
- Intrathecal administration of IL4-10 fusion protein significantly reduces the number of dorsal horn spinal cord c-Fos positive neurons.
- Knockdown of IL4R ⁇ and IL10R ⁇ in sensory neurons completely prevents IL4R-IL10R cross linking compound mediated attenuation of the c-Fos expression ( FIG. 3C ). Overall this indicates that both IL4R ⁇ and IL10R ⁇ in sensory neurons are required for the full inhibition of persistent inflammatory pain resulting from cross-linking IL4R and IL10R.
- mice received 4 injections of paclitaxel (8 mg/kg) every other day from day 0 to 6. Paclitaxel induced mechanical hyperalgesia that started on the first day after the first injection and that persisted at least 3 weeks after chemotherapy-treatment was stopped. Two days after the last paclitaxel injection, mice were injected intrathecally with 3 different doses of IL4-13 fusion protein (0.3, 1 and 3 ⁇ g/mouse) to cross-link IL4R and IL13R on cells in the dorsal root ganglion and the spinal cord ( FIG. 4A ).
- IL4-13 fusion protein 0.3, 1 and 3 ⁇ g/mouse
- cross-linking IL4R and IL13R An almost normalization of mechanical hyperalgesia lasting for at least a week was observed, demonstrating the potential of cross-linking IL4R and IL13R for long-lasting resolution of chemotherapy-induced polyneuropathy. Importantly, cross-linking IL4R and IL13R also reduced paclitaxel-induced intra-epidermal nerve fibre loss in the paw skin ( FIG. 4B ), demonstrating that this intervention prevents neuronal damage in vivo.
- ross-linking IL4R and IL13R provides neuroprotection against a broader spectrum of chemotherapy-induced polyneuropathy
- toxic neuropathy was also induced in mice using a platinum-based chemotherapeutic drug, oxaliplatin.
- Intrathecal injection of IL4-13 fusion protein on the second day after the last oxaliplatin injection reduced mechanical allodynia significantly for 4 days ( FIG. 4C ).
- Pro-inflammatory mediators sensitize sensory neurons for noxious and innocuous stimuli.
- cultured neurons were treated with TNF (50 ng/ml) with and without IL4-10 fusion protein, which was used to cross-link IL4R and IL10R (100 ng/ml, 3 nM).
- TNF significantly increased the magnitude of capsaicin-induced calcium influxes compared to untreated cells ( FIG. 5A-C ).
- Co-treatment with IL4-10 fusion protein completely prevents the sensitization of capsaicin-evoked calcium influx by TNF ⁇ .
- IL4-10 fusion protein affects capsaicin-induced calcium responses in non-sensitized neurons (not shown).
- cross-linking IL4R and IL10R inhibits PGE2-induced sensitization of capsaicin-induced calcium responses ( FIG. 5D-F ), without affecting normal capsaicin-induced calcium fluxes (not shown). This indicates that cross-linking IL4R and IL10R prevents neuronal sensitization by inflammatory mediators.
- IL4-10 fusion protein To identify whether the inhibitory effects of IL4-10 fusion protein on neuronal sensitization requires both cytokine binding moieties, separate receptor blocking antibodies were added. Blocking either IL4R or IL10R slightly reduced IL4-10 fusion protein-induced inhibition of TNF ⁇ -induced sensitization of capsaicin evoked calcium responses. Interestingly, blocking both IL4R and IL10R receptors completely abrogates inhibition of neuronal sensitization induced by IL4-10 fusion protein ( FIG. 5G ).
- cross-linking IL4R and IL10R to normalize neuronal sensitization by inflammatory mediators is superior to those of the combination of the wild-type cytokines.
- IL4-10 fusion protein dependently inhibits TNF ⁇ -induced sensitization of capsaicin-evoked calcium influx. At a concentration of 3 nM, it completely reversed TNF ⁇ -induced sensitization, whilst the combination of individual cytokines at the highest dose tested (30 nM) inhibited the TNF ⁇ -induced sensitization to a maximum of 50%. This indicates that cross-linking IL4R and IL10R has a superior potency over the combination of wild-type IL4 and IL10 to reduce neuronal sensitization by inflammatory mediators.
- mice sensory neurons were cultured in presence of oxaliplatin with or without IL4-13 fusion to cross-link IL4R and IL13R, or equimolar concentrations of wild-type IL4 and IL13 protein. Neurite length was measured to assess neurotoxicity. Oxaliplatin had a significant negative effect on neurite length when compared to the control group ( FIG. 6 ).
- IL4-13 fusion protein completely protected against oxaliplatin-induced neurotoxicity, whilst the combination of equimolar concentrations of wild-type IL4 and IL13 did not.
- An additional assay with two IL4-IL13 fusion proteins showed similar
- cross-linking IL4R and IL10R, or IL4R and IL13R induces effects in neurons that normalize the hypersensitization by inflammatory mediators and protect the cells against damage.
- these effects are unique to cross-linking involved receptors, since they are not induced by combinations of the wild-type cytokines tested at concentrations equimolar to that of the fusion proteins.
- Example 4 IL4-10 Fusion Protein Crosslinks IL4R and IL10R in Sensory Neurons
- the inventors decided to analyse the cellular processes induced by IL4-10 fusion protein in more detail.
- cross-linking of IL4R and IL10R by IL4-10 fusion proteins on neurons was demonstrated.
- IL4-10 fusion protein to cross-link IL4 and IL10 receptors raises the possibility that this drives unique downstream signaling events.
- PAMgene kinase activity profiling to assess global protein tyrosine kinases (PTK) and serine/threonine kinases (STK) activity in homogenates of lumbar DRGs of mice with persistent inflammatory pain after administration of IL4-10 fusion protein.
- PTK protein tyrosine kinases
- STK serine/threonine kinases
- Cross-linking IL4R and IL10R induces stronger phosphorylation of 5 peptide substrates for PTKs that were also activated by the combination of cytokines ( FIG. 8A ).
- Each of the peptides present in the kinase activity array can be substrates for different kinases, and one kinase or family of kinases can phosphorylate different peptides.
- the differential phosphorylation profiles are loaded into PhosphoNET.
- the inventors identified kinases, including the PTK platelet-derived growth factor receptor A (PDGFRa), KIT, fms like tyrosine kinase 3 (FLT3), MER or RET tyrosine kinases; the calcium calmodulin kinases (CAMK) such as CHK2, CAMK4 or DCAMKL2; AMPK, JAK1, and the Protein kinase A/G/C family such as AKT3, PKCb or NDR1/2.
- PTK platelet-derived growth factor receptor A PTK platelet-derived growth factor receptor A
- FLT3 fms like tyrosine kinase 3
- MER or RET tyrosine kinases the calcium calmodulin kinases (CAMK) such as CHK2, CAMK4 or DCAMKL2
- AMPK AMPK
- JAK1 Protein kinase A/G/C family
- kinases 8H include the PTKs KIT, PDGFRA, FER, MET and JAK1, and the STKs AKT3, LATS2, NDR2 or CAMK2.
- Pathway analysis of these predicted differentially can activate kinases indicates that the most active cellular processes induced by anti-IL4R-IL10R bispecific antibody treatment are mapped to immune responses, altered transcription, cell adhesion or cell cycle.
- the top 5 kinase substrates ranked by occurrence in the top 50 of the pathway analysis were NAPDH oxidase P47-phox, p120GAP, Rb protein, CDC25A and ZAP70.
- cross-linking IL4R and IL10R drives different signalling pathways, differential activation of kinases, different phosphorylation of kinase substrates, and a different kinomic profile compared to vehicle and compared to treatment with equivalent amounts of unlinked cytokines.
- PCA Principal component analysis
- the first principal component captures 55% variance of the data and separates the mice with cross-linking of IL4R and IL10R from mice that received vehicle or the combination of unfused cytokines, while the second principal component may capture 20% variance of the data and separates vehicle treated animals, indicating that IL4-10 fusion protein induces different transcriptome changes ( FIG. 9A ).
- Hierarchical clustering of the top 500 differentially regulated genes showed that based on their transcriptional profile the individual animals clustered based on the three different treatments ( FIG. 9B ).
- cross-linking IL4R and IL10R induces a different transcriptional profile compared to mice treated with IL4 and IL10 or vehicle.
- mice with the combination of IL4 and IL10 resulted in 4905 genes differentially expressed (FDR corrected p-value ⁇ 0.05) compared to those injected with PBS ( FIG. 9C ).
- KEGG Pathway analysis indicated that these genes aggregate in pathways affecting TLR signaling, oxidative phosphorylation, ribosomal proteins and lipid metabolism.
- 3995 genes are differentially expressed (FDR corrected p-value ⁇ 0.05) compared to those injected with vehicle.
- 1650 genes are increased, whilst 1375 are downregulated upon cross-linking IL4R and IL10R, as compared to the combination of cytokines.
- 1675 genes are uniquely regulated by IL4-10 fusion protein. From these uniquely regulated genes, the expression of 981 genes is increased by the fusion protein, whilst 694 are downregulated.
- Pathway analysis of the genes that are differentially expressed upon crosslinking of IL4R and IL10R as compared to the transcriptome of animals receiving the combination of wild-type IL4 and IL10 indicates that these genes belong to pathways including cytokine signaling, neurotrophin signaling, and pathways affecting innate and adaptative immune system indicating potential DRG-infiltrating immune cells ( FIG. 9E ). Additional analysis of upstream kinases based on KEGG pathways indicated that signalling pathways including cytokine and chemokine signaling, NOD-like receptor signaling or JAK-STAT signaling were affected ( FIG. 9F ).
- RNAseq data demonstrates that cross-linking IL4R and IL10R induces a unique transcriptome change as compared to animals treated with the combination of IL4 and IL10.
- KIT, PDGFRA, FER, MET and JAK1 were identified as the 5 highest ranking potential Tyrosine kinases that could be linked to the superior effects of IL4-10.
- IL4-10 differentially activates JAK1 in sensory neurons in vitro by was investigated by determining phosphorylation of JAK1 after stimulation of sensory neurons in vitro with IL4-10 or equimolar concentration of IL4 and IL10 for 10, 30 or 60 minutes. After 10 minutes, IL4-10 significantly increased pJAK1 in sensory neurons compared to vehicle and IL4+IL10 ( FIG. 10A ). At 30 minutes after stimulation both IL4-10 and IL4+IL10 increased pJAK1.
- c-Kit, PDGFR or c-Met kinases identified based on PAMgene and RNAseq data
- Inhibition of c-Kit or combined inhibition of c-kit and PDGFR did not affect IL4-10-induced inhibition of thermal hyperalgesia ( FIG. 10D ).
- inhibition of c-Kit and c-Kit and PDGFR enhanced the IL4-10-induced reduction in mechanical hyperalgesia by IL4-10 ( FIG. 10E ).
- Pharmacological inhibition of c-Met partially attenuated the pain-inhibiting effects of IL4-10 ( FIG. 10 D, E).

Abstract
Description
- This application is a continuation of International Application No. PCT/EP2020/60914 which claims priority to Dutch Patent Application No. 2022982 and Dutch Patent Application No. 2022984, each of which is incorporated herein by reference in its entirety.
- The instant application contains a Sequence Listing which has been submitted electronically in ASCII format and is hereby incorporated by reference in its entirety. Said ASCII copy, created on Nov. 18, 2021, is named 56780-704_301_SL.txt and is 65,718 bytes in size.
- The present disclosure relates to the treatment of chronic pain, osteoarthritis, inflammatory and immune disorders.
- Chronic pain is the number one reason why people seek medical advice in modern medicine. In spite of its multiple causes, chronic pain is accompanied by a cascade of biochemical reactions in the brain, spinal cord, dorsal root ganglia and peripheral nerves leading to neuroinflammation and neurodegeneration.
- An example of chronic pain is neuropathic pain, which is often described as a shooting or burning pain. This type of pain can be unrelenting and severe, and often results from nerve damage or a malfunctioning nervous system. Neuropathic pain has multiple causes including amputation, chemotherapy, diabetes, HIV infection, multiple myeloma, multiple sclerosis, nerve or spinal cord compression from herniated discs or from arthritis in the spine, shingles, spine surgery, and other. Neuropathic pain also occurs with no obvious cause. Unfortunately, neuropathic pain often responds poorly to standard pain treatments and occasionally may get worse instead of better over time. For some people, it can lead to serious disability.
- Another example of a chronic pain condition is osteoarthritis (OA). OA is the most common joint disorder; the majority of individuals over the age of 65 have radiographic and/or clinical evidence of OA. The most frequently affected sites are the hands, knees, hips, and spine. OA symptoms include chronic pain, significant functional impairment, stiffness, and loss of mobility. Importantly, in OA, the synovial tissue and cartilage produce pro-inflammatory cytokines, that induce chronic pain, inflammation and cartilage breakdown.
- Regulatory cytokines such as Interleukin-4 (IL4), IL10 and IL13 and others, have potential in the treatment of chronic pain, inflammatory diseases, immune disorders, and other conditions.
- However, cytokines as stand-alone drugs have limited therapeutic effects in chronic pain, immune, inflammatory and other biologic processes, and clinical application of these molecules for inflammatory and immune diseases has been disappointing.
- It is an objective of the present disclosure to overcome one or more problems in the prior art, and the present invention discloses a new approach to improve the therapeutic application of regulatory cytokine therapy, in particular interleukin-4 (IL4), IL27, IL10, and IL13.
- The inventors developed a novel therapeutic approach, which relates to induction of unique signaling of cells by crosslinking of the receptors of two different cytokines. This unique signaling is neither induced by individual cytokines, nor by the combination of cytokines.
- Compounds of the disclosure cluster or crosslink the IL4 receptor and a cytokine receptor, and surprisingly, elicit unique responses in the nervous system, including unique signaling and gene expression profiles. The signaling and gene expression profiles generated IL4-cytokine fusion proteins of the disclosure are distinct from those observed in response to the combination of IL4 and the cytokine, and contribute to the superior therapeutic effects over the combination of the component parts.
- Bringing a receptor binding moiety corresponding to a first cytokine and a receptor binding moiety corresponding to a second cytokine together to induce unique signaling (which does not occur when both receptors are triggered simultaneously by the wild-type cytokines), can be done with various constructs, such as with a bispecific antibody or a fusion protein.
- The approach according to the present disclosure, i.e., to apply cross-linking of at least two or three, preferably two receptors chosen from the group consisting of IL4R, IL10R, IL13R, IL27R, IL33R, TGFβ1R, and TGFβ2R by incorporating two or more moieties that bind to said receptors, into one molecule, for example a bispecific antibody, provides a unique treatment for chronic pain, neuro-inflammatory and neuro-degenerative diseases, and inflammatory and immune disorders. Moreover, the compounds disclosed herein, such as bispecific antibodies, have much better manufacturability, pharmacokinetic and safety profiles than cytokine-based drugs.
- As an example, the first cytokine can be IL4 and the second cytokine may be IL10 or IL13, and the resulting fusion protein can be an IL4-10 fusion protein or an IL4/13 fusion protein, respectively. Administration of the resulting receptor-crosslinking agent, for example a bispecific antibody against IL4-receptor (IL4R) and IL10-receptor (IL10R) or IL13-receptor (IL13R), may completely resolve chronic pain, reduce neuro-inflammation and protect against neurodegeneration in a human or animal subject, whilst administration of a combination of the individual cytokines IL4 and IL10 or IL13 cannot.
- Previously, the inventors have reported on the therapeutic effects of the IL4/IL10 fusion protein (N Eijkelkamp et al., J Neuroscience, 2016, 36 (28) 7353-7363). The inventors have now unraveled the mechanisms of action underlying the therapeutic application of the IL4-10 fusion protein according to the prior art, and found that the IL4-10 fusion protein surprisingly, contrary to the combination of IL4 and IL10, promoted clustering of the IL4 receptor (IL4R) and IL10 receptor (IL10R) on sensory neurons, which in turn promotes unique signaling pathways and gene expression profiles that can lead to a full resolution of persistent pain. The inventors now further found that an IL4-13 fusion protein induces a unique protection of neurons against the damaging effects of chemotherapeutic drugs in vitro as well as in vivo, which was dependent on cross-linking of IL4R and IL13R, as the combination of wild-type IL4 and wild-type IL13 does not provide such protection.

- Compounds of the disclosure can cluster or crosslink the IL4 receptor and a cytokine receptor, and surprisingly, elicit unique responses in the nervous system, including unique signaling and gene expression profiles. The signaling and gene expression profiles generated IL4-cytokine fusion proteins of the disclosure are distinct from those observed in response to the combination of IL4 and the cytokine, and can contribute to superior therapeutic effects over the combination of the component parts.
- In some embodiments, compounds (e.g., polypeptide constructs, fusion proteins) disclosed herein elicit unique and favorable responses in nervous system cells compared to equivalent amounts of IL4 and the cytokine individually. The disclosed compounds (e.g., polypeptide constructs, fusion proteins) can be useful for treating a condition disclosed herein in a subject in need thereof, including, for example, achieving superior therapeutic effects compared to equivalent amounts of IL4 and the cytokine administered separately or in combination (e.g., as a combination of unlinked cytokines).
- When describing a cytokine, the term “wild type” refers to a cytokine with an amino acid sequence that is naturally occurring and encoded by a germline genome of a given species. A species can have one wild type sequence, or two or more wild type sequences (for example, with one canonical wild type sequence and one or more non-canonical wild type sequences). A wild type cytokine sequence can include a sequence that is truncated at the N and/or C terminus relative to the sequence encoded by an open reading frame. A wild type cytokine sequence can be a mature form of a cytokine that has been processed to remove N-terminal and/or C-terminal residues. A wild type cytokine can lack a signal peptide or can include a signal peptide (e.g., a signal peptide can be added to the N-terminus of the wild type cytokine).
- When describing a cytokine, the term “derivative” refers to a cytokine with an amino acid sequence that differs from a wild type sequence by one or more amino acids, for example, containing one or more amino acid insertions, deletions, or substitutions relative to a wild type sequence. A cytokine derivative binds to at least one subunit of the corresponding native receptor for the wild type cytokine and elicits signaling and/or cytokine activity. The binding affinity, signaling, and/or cytokine activity of a cytokine derivative can be the same or different than the corresponding wild type cytokine.
- The term “nervous system cell” refers to a cell that is found within the central nervous system or peripheral nervous system. A nervous system cell can be a neuron, a central nervous system cell, a peripheral nervous system cell, a glial cell, a microglial cell, an astrocyte, a Schwann cell, a satellite glial cell, an oligodendrocyte, an infiltrating cell, an infiltrating immune cell, an infiltrating myeloid cell, an infiltrating lymphoid cell, an infiltrating macrophage, an infiltrating neutrophil, an infiltrating lymphocyte, an infiltrating T cell, an infiltrating B cell, or an infiltrating natural killer cell. A neuron can be, for example, a sensory neuron, a somatosensory neuron, a visceral sensory neuron, a nociceptor, and/or an autonomic neuron.
- “Sequence identity” and “sequence similarity” can be determined by alignment of two peptide or two nucleotide sequences using global or local alignment algorithms. Sequences may then be referred to as “substantially identical” or “essentially similar” when they (when optimally aligned by for example the programs GAP or BESTFIT using default parameters) share at least a certain minimal percentage of sequence identity. GAP uses the Needleman and Wunsch global alignment algorithm to align two sequences over their entire length, maximizing the number of matches and minimizes the number of gaps. Generally, the GAP default parameters are used, with a gap creation penalty=50 (nucleotides)/8 (proteins) and gap extension penalty=3 (nucleotides)/2 (proteins). For nucleotides the default scoring matrix used is nwsgapdna and for proteins the default scoring matrix is Blosum62 (Henikoff & Henikoff, 1992,
PNAS 89, 915-919). Sequence alignments and scores for percentage sequence identity may be determined using computer programs, such as the GCG Wisconsin Package, Version 10.3, available from Accelrys Inc., 9685 Scranton Road, San Diego, Calif. 92121-3752 USA, or EmbossWin version 2.10.0 (using the program “needle”). Alternatively, percent similarity or identity may be determined by searching against databases, using algorithms such as FASTA, BLAST, etc. Sequence identity can refer to the sequence identity over the entire length of the sequence. - A compound (e.g., polypeptide construct, fusion protein) disclosed herein can comprise an IL4 protein, or a variant, derivative or fragment thereof operably connected or directly or indirectly fused to at least one additional cytokine or a variant, derivative or fragment thereof. The IL4 protein can be a mammalian IL4 protein, such as a human IL4, or mouse IL4. Non-limiting examples of amino acid sequences of IL4 are set forth in SEQ ID NOs: 11-14.

TABLE 8 Non-limiting examples of linker sequences of the disclosure SEQ ID NO: SEQUENCE 38 GSGGGGSGT 39 GGGS 40 GGGGS 41 KESGSVSSEQLAQFRSLD 42 EGKSSGSGSESKST 43 GSAGSAAGSGEF 44 EAAAK 45 EAAAR - A linker as described herein can include a flexible or rigid linker. A flexible linker can have a sequence containing stretches of glycine and serine residues. The small size of the glycine and serine residues provides flexibility, and allows for mobility of the connected functional domains. The incorporation of serine or threonine can maintain the stability of the linker in aqueous solutions by forming hydrogen bonds with the water molecules, thereby reducing unfavorable interactions between the linker and protein moieties. Flexible linkers can also contain additional amino acids such as threonine and alanine to maintain flexibility, as well as polar amino acids such as lysine and glutamine to improve solubility.
- A flexible linker can comprise SEQ ID NO: 38. A flexible linker can comprise repeats of SEQ ID NO: 39 (GGGS), for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 repeats of SEQ ID NO: 39. A flexible linker can comprise repeats of SEQ ID NO: 40 (GGGGS), for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 repeats of SEQ ID NO: 40. Several other types of flexible linkers, including SEQ ID NO: 41 (KESGSVSSEQLAQFRSLD) and SEQ ID NO: 42 (EGKSSGSGSESKST), can also be used. The SEQ ID NO: 43 (GSAGSAAGSGEF) linker can also be used, in which large hydrophobic residues are minimized to maintain good solubility in aqueous solutions. The length of the flexible linkers can be adjusted to allow for proper folding or to achieve optimal biological activity of the fused proteins.
- A rigid linker can have, for example, an alpha helix-structure. An alpha-helical rigid linker can act as a spacer between protein domains. A rigid linker can comprise repeats of SEQ ID NO: 44 (EAAAK), for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 repeats of SEQ ID NO: 44. A rigid linker can comprise repeats of SEQ ID NO: 45 (EAAAR), for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 repeats of SEQ ID NO 45. A rigid linker can have a proline-rich sequence, (XP)n, with X designating alanine, lysine, glutamine, or any amino acid. The presence of proline in non-helical linkers can increase stiffness, and allow for effective separation of protein domains.
- A linker of the disclosure can include a non-peptide linker, for example, a chemical linker. For example, two amino acid sequences of the disclosure can be connected together by a chemical linker. Each chemical linker of the disclosure can be alkylene, alkenylene, alkynylene, heteroalkylene, cycloalkylene, heterocycloalkylene, arylene, or heteroarylene, any of which is optionally substituted. In some embodiments, a chemical linker of the disclosure can be an ester, ether, amide, thioether, or polyethyleneglycol (PEG). In some embodiments, a linker can reverse the order of the amino acids sequence in a compound, for example, so that the amino acid sequences linked by the linked are head-to-head, rather than head-to-tail. Non-limiting examples of such linkers include diesters of dicarboxylic acids, such as oxalyl diester, malonyl diester, succinyl diester, glutaryl diester, adipyl diester, pimetyl diester, fumaryl diester, maleyl diester, phthalyl diester, isophthalyl diester, and terephthalyl diester.

- In some embodiments, the present disclosure relates to a compound comprising:
-
- a first binding moiety that binds to a first interleukin receptor, preferably an
interleukin 4 receptor (IL4R),interleukin 10 receptor (IL10R),interleukin 27 receptor (IL27R), aninterleukin 13 receptor (IL13R), IL27R, or to an IL33 receptor, a TGFβ1 receptor, and a TGFβ2 receptor; and - a second binding moiety that binds to a second interleukin receptor, preferably chosen from the group consisting of an
interleukin 4 receptor (IL4R),interleukin 10 receptor (IL10R), aninterleukin 13 receptor (IL13R), an IL33 receptor, a TGFβ1 receptor, and a TGFβ2 receptor.
- a first binding moiety that binds to a first interleukin receptor, preferably an
- For example, the first binding moiety may bind to an
interleukin 4 receptor (IL4R). Or, the first binding moiety may bind to aninterleukin 10 receptor (IL10R). Alternatively, the first binding moiety may bind to aninterleukin 13 receptor (IL13R) or IL27R. Still alternatively, the first binding moiety may bind to an IL33 receptor. Or, the first binding moiety may bind to a TGFβ1 receptor. Further, the first binding moiety may bind to a TGFβ2 receptor. - In some embodiments, the present disclosure relates to a compound comprising:
-
- a first binding moiety that binds to a first interleukin receptor, preferably an
interleukin 4 receptor (IL4R); and - a second binding moiety that binds to a second interleukin receptor, preferably chosen from the group consisting of an
interleukin 10 receptor (IL10R), and aninterleukin 13 receptor (IL13R).
- a first binding moiety that binds to a first interleukin receptor, preferably an
- In some embodiments, preferably, the first binding moiety and/or the second binding moiety is not a (wild-type) interleukin, and/or does not comprise a (wild-type) interleukin-derived amino acid sequence.
- It was found that a compound according to the present disclosure is able to induce unique signaling in neurons, glial cells and other target cells, and can in particular be applied as a treatment of chronic pain and other conditions disclosed herein.
- The compound according to the present disclosure may be any kind of compound that can cross-link cytokine receptors disclosed herein (e.g., IL4R and IL10R or IL13R). This compound can be, for example, a complex, or a polypeptide, a fusion protein, or more preferably a bispecific antibody, a bivalent single chain antibody, a bispecific double chain antibody, a triabody, or a tetrabody. The term “first” and “second” binding moiety does not refer to their relative orientation in the compound, i.e. the first binding moiety can be N- or C-terminal to the second binding moiety, or any alternative configuration may be used. The term “first” and “second” only serves to correctly refer to the two different binding moieties in the present disclosure.
- The dual binding (or multi binding) compound according to the present disclosure can be employed to connect (e.g. cluster or cross-link) an IL4R and an IL10R or an IL13R in vivo, preferably an IL4R and an IL10R or an IL13R on a sensory neuron or on a glial cell.
- In an alternative embodiment, the present disclosure provides for a combination comprising:
-
- a first binding moiety that binds to an IL4R;
- a second binding moiety that binds to an IL10R or an IL13R,
- wherein the first binding moiety has a linker that binds the second binding moiety or
- wherein the second binding moiety has a linker that binds the first binding moiety.
- In some embodiments, the first binding moiety and/or the second binding moiety is not a (wild-type) interleukin and/or does not comprise a (wild-type) interleukin-derived amino acid sequence. In some embodiments, a compound (e.g., polypeptide construct, fusion protein) of the disclosure does not contain SEQ ID NO: 11. In some embodiments, a compound (e.g., polypeptide construct, fusion protein) of the disclosure does not contain SEQ ID NO: 15. In some embodiments, a compound (e.g., polypeptide construct, fusion protein) of the disclosure does not contain SEQ ID NO: 46.
- The above-mentioned combination can also be employed to connect (cluster or cross-link) cytokine receptors (e.g., an IL4R and an IL10R IL13R, IL27R, IL33R, or TGFβ1R, TGFβ2R) in vivo, for example, an IL4R and an IL10R or an IL13R of a sensory neuron or a glial cell. In this embodiment, the first binding moiety and/or second binding moiety may comprise a tag, and the linker of the respective other binding moiety preferably is a polypeptide that binds to the tag.
- The compound or combination according to the present disclosure is provided particularly for use as a medicament or for use in a therapeutic treatment, preferably the treatment of (inflammatory) pain, e.g. chronic (inflammatory) pain, or neurodegenerative disease.
- The first binding moiety, the second binding moiety, and/or the linker according to the present disclosure may be or encompass for example a polypeptide, either or not containing sequences of IL4 and IL10 or IL13, respectively, or more preferably an immunoglobulin molecule or epitope-binding fragment thereof, in particular Fab, F(ab′), F(ab′)2, Fv, dAb, Fd, or a complementarity determining region (CDR) fragment, a single chain antibody (scFv), or single domain antibody. A binding moiety or linker according to the present disclosure may thus be or encompass an intact immunoglobulin molecule such as a polyclonal or monoclonal antibody.
- A monoclonal (full) antibody comprises two light chains and two heavy chains, each comprising three CDRs, and has a total of 12 CDRs. A CDR region is a variable sequence involved in the physical binding of the antibody to its antigen.
- It is possible to select CDR sequences from other species, e.g. murine, and exchange these with CDR sequences in a human immunoglobulin molecule, to obtain a human immunoglobulin molecule having the specificity that is derived from the other species. This may be advantageous as a human sequence may be less immunogenic to humans as compared to the original framework sequence. Such an exchange of CDR sequences is known as humanization. Hence, the compound, immunoglobulin molecule, or first and/or second binding moiety as provided by the disclosure may be humanized.
- The first binding moiety, second binding moiety and/or linker according to the present disclosure preferably specifically binds to its respective target. With the term “specifically bind(s) to” is meant that the binding moiety or linker has more affinity towards its target (e.g. human IL4R or human IL10R) or human IL13R than to other molecules present in the target environment (e.g. the human body). The affinity of an antibody to its antigen is expressed as KD (the equilibrium dissociation constant between the antibody and its antigen). It is preferred that the KD of both antigen binding sites of any of the binding moieties disclosed here is lower than 10−5 M, more preferably lower than 10−7 M, more preferably lower than 10−9 M, more preferably lower than 10−10 M.
- The compound, first binding moiety, second binding moiety and/or linker according to the present disclosure may be or encompass a single domain antibody. Single domain antibodies (sdAb, also called Nanobody, or VHH) are well known to the skilled person. Single domain antibodies are antibodies whose complementarity determining regions are part of a single domain polypeptide. Single domain antibodies thus comprise a single CDR1, a single CDR2 and a single CDR3. Examples of single domain antibodies are heavy chain only antibodies, antibodies that do not comprise light chains, single domain antibodies derived from conventional antibodies, and engineered antibodies. Single domain antibodies may be derived from any species including mouse, human, camel, llama, goat, rabbit, and bovine. For example, naturally occurring VHH molecules can be derived from Camelidae species, for example in camel, dromedary, alpaca and guanaco.
- Like a whole antibody, a single domain antibody is able to bind selectively to a specific target. Single domain antibodies contain only the variable domain of an immunoglobulin chain having CDR1, CDR2 and CDR3 and framework regions. With a molecular weight of only about 12-15 kDa, single domain antibodies are much smaller than regular antibodies (150-160 kDa) which are composed of at least two heavy chains and two light chains. The format of a single domain antibody has the advantage of less sterical hindering when bound to its target and may bind to epitopes not accessible to regular antibodies. This is both advantageous for the specific blocking and cross-linking properties as aimed for in the present disclosure. One other advantage may be that in the case of an allogenic source, single domain antibodies may be less immunogenic in other species than (full) monoclonal antibodies.
- In a further aspect of the present disclosure, the compound, first binding moiety and/or second binding moiety according to the present disclosure may comprise a polypeptide selected from the group consisting of a signal sequence, an affinity tag (e.g., a His-tag), and an antibody Fc fragment. Additionally, and/or alternatively, the compound, first binding moiety and/or second binding moiety according to the present disclosure may comprise one or more chemical modifications selected from the group consisting of glycosylation, sialylation, fucosylation, and pegylation.

The term “chronic” can be defined at persisting for at least 1, 2, 3, 4, 5, 6, 8, 10, or 12 weeks, at least 1, 2, 3, 4, 5, 6, 8, 10, or 12 months, and/or at least 1, 2, 3, 4, or 5 years.
- The compound or combination of the present disclosure may be prepared by techniques which are routine to the skilled person. For example, it may be prepared using a technique which provides for the production of recombinant proteins by continuous cell lines in culture. For example, the compound or combination of the present invention can be produced in a host cell using a combination of recombinant DNA techniques and gene transfection methods.
- For example, to express the compound or combination according to the present disclosure, a nucleic acid molecule encoding the compound or (components of the) combination can be prepared by standard molecular biology techniques. The nucleic acid molecule of the disclosure is preferably operably linked to transcription regulatory sequences such as a promoter, and optionally a 3′ untranslated region. The nucleic acid molecule of the present disclosure may be inserted into a vector, such as an expression vector, such that the genes are operatively linked to transcriptional and translational control sequences. The expression vector and transcription regulatory sequences are selected to be compatible with the expression host cell used. The nucleic acid molecule encoding a compound or (component(s) of the) combination of the present disclosure may be inserted into the expression vector by routine methods.
- Additional amino acid sequences may be present at the N- and/or C-terminus of a compound or polypeptide construct (e.g., fusion protein) for example, at any one or both of the first and second binding moieties according to the present disclosure, e.g., to facilitate purification. For example, a poly-histidine-tag, GST-tag, FLAG-tag, CBP tag, HA tag, or Myc tag may be present at the C- or N-terminus to facilitate purification. In some embodiments, an affinity tag is removed from a compound (e.g., polypeptide construct, fusion protein) of the disclosure, e.g., after purification. In some embodiments, a compound (e.g., polypeptide construct, fusion protein) of the disclosure does not contain an affinity tag, (e.g., the compound can be purified by other methods). Alternatively or additionally, the compound, polypeptide construct (e.g., fusion protein) or combination according to the present disclosure may optionally comprise additional protein moieties, such as moieties capable of targeting, e.g., a protein moiety comprising one or more antibody Fc regions.

In some embodiments, a compound (e.g., fusion protein, polypeptide construct) comprises an extracellular matrix-binding polypeptide.
- The compound or combination according to the present disclosure is preferably an isolated (combination of) protein(s) which can be seen as a protein which is no longer in its natural environment, for example in vitro or in a recombinant host cell.
- The present disclosure also encompasses a cell (line) expressing the compound or (first and/or second binding moiety of the) combination as disclosed herein, preferably a Chinese hamster ovary (CHO) cell line, which provides a popular mammalian host for large-scale commercial production of compound or combinations as these cells are safe and allow high volumetric yields.
- In another aspect, the present disclosure relates to a host cell comprising a nucleic acid sequence of the present disclosure, or a nucleic acid construct or vector comprising a nucleic acid sequence of the present disclosure. The host cell may be any host cell that can transiently or permanently express the compound or (components of the) combination. The host cell is preferably an animal cell or cell line, such as a mammalian cell or cell line.
- In one embodiment the compound or (components of the) combination of the present disclosure is expressed in eukaryotic cell, such as mammalian host cell. Preferred mammalian host cells for expressing include CHO cells (including dhfr-CHO cells, described in (Urlaub et al., 1980), used with a DHFR selectable marker, NS/0 myeloma cells, COS cells, HEK293 cells and SP2.0 cells. When recombinant expression vectors comprising nucleic acid sequences encoding the compound or (components of the) combination are introduced into mammalian host cells, they may be produced by culturing the host cells for a period of time sufficient to allow for expression of the compound or (components of the) combination in the host cells or, more preferably, secretion of thereof into the culture medium in which the host cells are grown. The compound or combination of the present disclosure may be recovered from the culture medium in which the host cells are grown and/or may be purified from the culture medium using standard protein purification methods.
- Alternatively, the nucleic acid sequences encoding the compound or (components of the) combination of the disclosure can be expressed in other expression systems, such as e.g. algae, as well as insect cells.

For expression of the compound or combination of the present disclosure, the expression vector(s) encoding the compound or combination may be transfected into a host cell by standard techniques. The various forms of the term “transfection” are intended to encompass a wide variety of techniques commonly used for the introduction of exogenous DNA into a prokaryotic or eukaryotic host cell, e.g., electroporation, calcium-phosphate precipitation, DEAE-dextran transfection, lipofectamine transfection, and freeze-dry method transfection, and the like. Cell lines that secrete the compound or combination of the present disclosure can be identified by assaying culture supernatants for the presence of the compound or combination. The preferred screening procedure comprises two sequential steps, the first being identification of cell lines that secrete the compound or combination, the second being determination of the quality of the compound or combination such as the ability thereof to inhibit cytokine production by blood cells stimulated with LPS or other Toll-like receptor agonists, and others.
- In an aspect, the present invention is concerned with a method for producing the compound or combination according to the present disclosure, said method comprising the steps of: culturing a host cell of the present invention under conditions permitting the production of the compound or combination; and optionally, recovering the compound or combination. The skilled person will be capable of routinely selecting conditions permitting production of the compound or combination of the present disclosure. Additionally, a person skilled in the art will be capable of recovering the compound or combination produced using routine methods, which include, without limitation, chromatographic methods (including, without limitation, size exclusion chromatography, hydrophobic interaction chromatography, ion exchange chromatography, affinity chromatography, immunoaffinity chromatography, metal binding, and the like), immunoprecipitation, HPLC, ultracentrifugation, precipitation and differential solubilisation, and extraction. As said above, recovery or purification of the compound or combination of the present disclosure may be facilitated by adding, for example, a Histidine-tag to the fusion protein.
- In some cases, compounds (e.g., polypeptide constructs, fusion proteins) disclosed herein contain two cytokines, C1 and C2, and are referred to in the format C1/C2 or C1-C2. The order in which the cytokines are presented is not limiting and does not necessarily infer the orientation of the cytokines. For example, C1/C2 or C1-C2 can contain cytokine C1 on the C-terminal side of C2 or on the N-terminal side of C2. Similarly, a cytokine referred to as C1/C2 can be the same as a cytokine referred to as C2/C1 unless otherwise specified.
- In this document and in its claims, the verb “to comprise” and its conjugations is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. In addition, reference to an element by the indefinite article “a” or “an” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements. The indefinite article “a” or “an” thus usually means “at least one”.
- To improve the therapeutic potency of regulatory cytokines such as IL4, IL10 and IL13, the present invention discloses that unique signalling of intracellular processes is induced by crosslinking of receptors for these regulatory cytokines and that this unique signalling in cells in the dorsal root ganglia and the dorsal horn of the spinal cord results in an unprecedented analgesic effect.
- Moreover, the present invention provides several compounds that can be used to crosslink regulatory cytokine receptors to induce such a unique cell signalling, which can be used as a medicament to treat chronic pain, and neuro-inflammatory and neurodegenerative conditions. These compounds include genetically engineered bispecific antibody that binds to two different receptors for regulatory cytokines, such as the IL4 receptor (IL4R) and the IL10 receptor (IL10R), or the IL4R and the IL13 receptor (IL13R). Such bispecific antibodies have potent analgesic effects—surprisingly they inhibit chronic pain more effectively than the mere sum of the combination of the two cytokine moieties. Moreover, injection of the anti-IL4R-IL10R bispecific antibody or anti-IL4R-IL13R bispecific antibody may completely resolve chronic pain in animal models.
- In order to understand how a bispecific antibody against regulatory cytokine receptors exert its unique analgesic and neuroprotective effects, the inventors considered the mechanisms of action of a fusion protein that binds to both IL4R and IL10R and displays potent analgesic properties.
- Similarly, they analysed the potency and mechanisms of a fusion protein that binds to both IL4R and IL13R and which has superior analgesic activity compared to the combination of wild-type IL4 and IL10. To that end, the inventors looked at the way in which cross-linking of IL4R and IL10R may transduce signals to the sensory nervous system. The inventors envisage that the superior analgesic effects resulting from cross-linking IL4R and IL10R result from a unique signalling process that has a unique effect on pain resolving pathways in sensory neurons. To confirm the general applicability of cross-linking of regulatory cytokine receptors as a therapeutic approach for chronic pain, neuroinflammation and neuro-degeneration, the inventors also evaluated the effects of cross-linking IL4 and IL13 receptors.
- All animal experiments are performed in accordance with international guidelines and with prior approval from the University Medical Center Utrecht experimental animal committee. Experiments were conducted using both male and female mice, all of which were between 8-14 weeks old when tested. Observers who performed the behavioral experiments were blind to the mouse genotype and treatment. The following mice were used: wild type (WT) C57BL/6 mice (Envigo, The Netherlands). For generation of nociceptor-specific IL10R knockout mouse strains we used the Cre-loxP system (Sauer B & Henderson N (1988) Site-specific DNA recombination in mammalian cells by the Cre recombinase of bacteriophage P1. Proc Natl Acad Sci USA 85(14):5166-5170). Floxed IL10R mice (Pils M C, et al. (2010) Monocytes/macrophages and/or neutrophils are the target of IL-10 in the LPS endotoxemia model. Eur J Immunol 40(2):443-448) were crossed with Nav1.8-Cre mice (Nassar M A, et al. (2004) Nociceptor-specific gene deletion reveals a major role for Nav1.7 (PN1) in acute and inflammatory pain. Proc Natl Acad Sci USA 101(34):12706-12711) in which Cre expression is driven by the Nav1.8 promoter that is expressed in >90% of nociceptors (Shields S D, et al. (2012) Nav1.8 expression is not restricted to nociceptors in mouse peripheral nervous system. Pain 153(10):2017-2030).
- Mice received an intraplantar injection of 20 μl λ-carrageenan (2% (w/v), Sigma-Aldrich) dissolved in saline solution (NaCl 0.9%) in both hind paws. To induce transient chemotherapy-induced polyneuropathy (CIPN), paclitaxel (2 mg/kg, Cayman Chemical Company) was injected intraperitoneally on
days day - To induce transient chemotherapy-induced polyneuropathy (CIPN), paclitaxel (2 mg/kg, Cayman Chemical Company) was injected intraperitoneally on
days day - Thermal hyperalgesia was assessed by determining the heat withdrawal latency times using the Hargreaves test (IITC Life Science) (Hargreaves K, Dubner R, Brown F, Flores C, & Joris J (1988) A new and sensitive method for measuring thermal nociception in cutaneous hyperalgesia. Pain 32(1):77-88). Mechanical thresholds were determined using the von Frey test with the up-and-down method (Chaplan S R, Bach F W, Pogrel J W, Chung J M, & Yaksh T L (1994) Quantitative assessment of tactile allodynia in the rat paw. J Neurosci Methods 53(1):55-63). All experimenters were blind to genotype and/or treatment.
- IL4-10 protein was produced in HEK293 cells and purified as described previously (Eijkelkamp N, et al. (2016) IL4-10 Fusion Protein Is a Novel Drug to Treat Persistent Inflammatory Pain. J Neurosci 36(28):7353-7363). Similarly, a fusion protein of IL4 and IL13 (IL4-13) was produced. IL4-10 and IL4-13 fusion protein concentrations were determined based on IL10 ELISA (IL4 Pelipair ELISA kit, Sanquin; IL13 and IL10, DuoSet ELISAs, R&D Systems), as well as on Bicinchoninic Acid Protein Assay (BCA Pierce Protein Assay Kit, ThermoFisher Scientific). Intrathecal (i.t.) injections of different compounds (5 μl/mouse) were performed as described before (Eijkelkamp N, et al. (2010) GRK2: a novel cell-specific regulator of severity and duration of inflammatory pain. J Neurosci 30(6):2138-2149) under light isoflurane/O2 anaesthesia. The IL4-10 fusion protein (1 μg/mouse) or equimolar doses of recombinant human IL4 and IL10 (Sigma) were injected intrathecally at
day 6 after intraplantar λ-carrageenan injection. - IL4Rα expression in sensory neurons was knocked down by intrathecal injections of antisense oligodeoxynucleotides (asODN) directed against IL4Rα mRNA (Ripple M J, et al. (2010) Immunomodulation with IL-4R alpha antisense oligonucleotide prevents respiratory syncytial virus-mediated pulmonary disease. J Immunol 185:4804-4811). This approach has been shown to successfully inhibit the expression of several proteins in dorsal root ganglia (DRG) neurons (Stone L S & Vulchanova L (2003) The pain of antisense: in vivo application of antisense oligonucleotides for functional genomics in pain and analgesia. Adv Drug Deliv Rev 55(8):1081-1112). AsODN were dissolved in saline (15 μg per 5 μl) and injected intrathecally at
day - Mice were deeply anaesthetised with an injection of pentobarbital (60 mg/kg; intraperitoneal) and transcardially perfused with Phosphate-buffered saline (PBS; 140 mM NaCl2, 20 mM Na2HPO4, 2.4 mM NaH2PO4) followed by 4% paraformaldehyde (PFA) in PBS (Klinipath). Lumbar DRGs and spinal cords (lumbar L3-L5 section) were isolated and postfixed in 4% PFA cryoprotected in sucrose, and embedded and frozen in optimal cutting temperature (OCT) compound (Tissue-Tek, Sakura). For IL4R and IL10R stainings, DRGs were directly frozen in OCT without prior fixation. Spinal cords and DRGs were cut in 20 μm and 10 μm thick sections respectively using a cryostat (CM 3050S; Leica). Sections were collected on SuperFrost plus microscope slides (VWR International).
- IL4R and IL10R: Sections were fixed with 10% neutral buffer formalin for 10 min and incubated in PBS containing 0.3% Triton X-100 (PBS-T) and 5% normal donkey serum (NDS)). Cultured primary sensory neurons were fixed with 4% PFA for 10 minutes and incubated in PBS containing 0.05% Tween-20, 1% bovine serum albumin (BSA) and 5% NDS). Sections and cells were incubated overnight at 4° C. with rabbit anti-IL4Rα (sc-686, Santa Cruz; 1:100), rabbit anti-IL10Rα (sc-985, Santa Cruz; 1:100), mouse anti-Neurofilament 200 (NO142, Sigma; 1:500), mouse anti-Peripherin (MAB1527, Millipore; 1:100) or Isolectin B4 (B1205, Vector; 1:50) diluted in antibody diluent (PBS-T with 2% BSA). Subsequently, sections were incubated with alexafluor 488- or 594-conjugated secondary antibodies (Thermofisher, 1:1000) followed by DAPI (1:1000, Sigma) staining before sections were mounted on slides with FluorSave reagent (Millipore).
- For staining of c-Fos, a marker for neuronal activation, we performed a colorimetric staining as described previously (64) with some modifications. Serial spinal cord sections were incubated in PBS-T containing 0.1% BSA and 2% NDS. Subsequently, sections were incubated with rabbit anti c-Fos (sc-52, Santa Cruz; 1:500) overnight at 4° C. After washing, sections were incubated with Biotin SP conjugated donkey anti-rabbit IgG (1:250, Jackson IR Laboratories) for 90 minutes. Subsequently, sections were incubated with Vector ABC-Elite (1:50, Vector Laboratories) for 90 minutes. Thereafter, sections were developed with diaminobenzidine (DAB)-Nikel solution (0.05M Tris HCl pH 7.6; 3 mg/ml (NH4)2Ni(SO4)2; 25 mg/ml DAB (1:100, Sigma), hydrogen peroxide (0.1 μl/ml). Finally, the sections were dehydrated and mounted with DePeX (Serva).
- Images were taken using a Zeiss Axio Lab A1 (Zeiss). Pictures were analysed with ImageJ (NIH).
- DRGs were cultured as described previously (Eijkelkamp N, et al. (2013) A role for Piezo2 in EPAC1-dependent mechanical allodynia. Nat Commun 4:1682). Briefly, DRGs were dissected and placed on ice-cold dissection medium (HBSS w/o Ca2+ and Mg2+, 5 mM HEPES, and 10 mM glucose). After dissection, axons were cut and dissection medium was replaced by filtered enzyme mix (HBSS w/o Ca2+ and Mg2+, 5 mM HEPES, 10 mM glucose, 5 mg/ml collagenase type XI (Sigma), and 10 mg/ml Dispase (Gibco)). The DRGs were incubated in enzyme mix for 30 minutes at 37° C. and 5% CO2. Subsequently, enzyme mix was inactivated with heat-inactivated foetal bovine serum (FBS, Sigma). Cells were cultured in Dulbecco's modified Eagle's medium (Gibco) containing 10% FBS (Gibco), 2 mmol/L glutamine (Gibco), 10,000 IU/ml penicillin-streptomycin (Gibco) on poly-L-lysine (0.01 mg/ml, Sigma) and laminin (0.02 mg/ml, Sigma)-coated glass coverslips in a 5% CO2 incubator at 37° C. Cells were used the following 1-2 days.
- To evaluate the effect of cross-linking IL4R, IL10R and IL13R on the damage to neurons induced by chemotherapeutic drugs, cells were incubated in 24 wells plates for 24 hours in presence of paclitaxel (1 uM) or oxaliplatin (5 ug/ml) to induce neurotoxicity. IL4-10 fusion protein (100 ng/mL), IL4-13 fusion protein (100 ng/mL), IL4 an IL13 (50 ng/mL each), IL4 (50 ng/mL), IL10 (50 ng/mL), and IL13 (50 ng/mL) were added together with the chemotherapeutic agent. As controls cells were also cultured in absence of chemotherapeutic drugs or cytokines, and in presence of chemotherapeutic drugs only. After fixation with 4% paraformaldehyde, cells were stained with rabbit anti-mouse βIII-tubulin (ab18207, 1:1000; Abcam). Neurites were visualized with a Zeiss Axio Lab A1 microscope (Zeiss-Oberkochen, Germany) and using a random sampling method, at least 10 images per glass slide were made at a magnification of 10×. The length of neurites was measured with the ImageJ plugin Simple Neurite Tracer76. The averages of neurite length per neuron for a minimum of five neurons per condition were compared between groups for the three individual primary sensory cultures.
- DRG neurons used for calcium imaging experiments were stimulated overnight with TNFα (50 ng/ml, Peprotech) with or without the IL4-10 fusion protein (100 ng/ml; 3 nM), recombinant IL4 and IL10 (50 ng/ml each; 3.3 and 2.9 nm, respectively) and/or receptor blocking antibodies targeted against mouse IL4R or IL10R (2 μg/ml, BD pharmingen).
- To measure changes in the capsaicin-evoked calcium response, cells were loaded with 5 μM Fura-2-AM (Invitrogen) for 25 minutes in 140 mM NaCl, 4 mM KCl, 1 mM MgCl2, 2 mM CaCl2, 10 mM HEPES, and 10 mM Glucose; pH 7.4. Cells were excited at 340 and 380 nm wavelengths and fluorescence was collected every 3 seconds at 510 nm using an Axio Observer A1 inverted microscope (X20 objective, Zeiss). The ratio 340/380 is directly correlated with the amount of intracellular calcium.
- Recordings were performed as previously described (66) with some modifications. Briefly, every experiment included a 5 minutes baseline measurement followed by a stimulation of the cells by superfusion with capsaicin (0.03 μM) for 21 seconds followed by superfusion of medium. A subsequent 5 minutes of superfusion with high K*-buffer (4 mM NaCl, 140 mM KCl, 1 mM MgCl2, 2 mM CaCl2, 10 mM HEPES, and 10 mM Glucose; pH 7.4) was added at the end of each experiment to depolarize the neurons to confirm cell viability and functionality.
- Lumbar DRGs were homogenized using TRIzol (Invitrogen). Total RNA was extracted using the RNeasy Mini Kit (Qiagen) and 1 μg of total RNA was used to synthesize cDNA. cDNA was synthesized using SuperScript reverse transcriptase (Invitrogen). RNA concentrations were determined using a NanoDrop 2000 (Thermo Scientific).
- The real-time PCR reaction using SYBRgreen master mix (BioRad) was performed on an iQ5 Real-Time PCR Detection System (BioRad). Primers used for qPCR are listed in table 9. The mRNA expression levels were normalized for GAPDH, HRPT and actin.

IL10Rα antibody was labelled with biotin using EZ-Link™ Sulfo-NHS-LC-Biotin SMCC (ThermoFischer). The Biotin-PLUS-probe was later bound to the antibody with streptavidin.
- Primary DRG cultures were treated with IL4-10 fusion protein (100 ng/ml; 3 nM) or the combination of IL4 and IL10 (50 ng/ml each; 3.3 and 2.9 nM, respectively) for 15 minutes and fixed with 4% PFA for 10 minutes. In situ PLA was performed as described (Soderberg O, et al. (2008) Characterizing proteins and their interactions in cells and tissues using the in situ proximity ligation assay. Methods 45(3):227-232) with some modifications. Samples were blocked with blocking buffer (PBS containing 0.05% Tween-20, 1% BSA and polyA 1:100). Subsequently, samples were incubated overnight at 4° C. with the following antibodies: MINUS probe-labelled rabbit-anti IL4Rα and biotin-labelled rabbit-anti-IL10Rα. For controls biotin-labelled rat anti-CD200 (Serotec) was used instead of anti-IL10Rα antibody. Next, samples were incubated with streptavidin (5 μg/ml) for 25 minutes at room temperature and incubated with biotin linked to a PLUS probe for 30 minutes at room temperature. T4 DNA ligase (5 Weis units/μl) and the circle and linker probes were added (in the presence of 0.1 M DTT and 3 mM ATP) and incubated at 37° C. for 50 minutes in PHI buffer (50 mM Tris-HCl, 10 mM MgCl2, 10 mM (NH4)2SO4, pH 7.5+0.05% Tween20). After washing, samples were incubated with PHI polymerase (kindly donated by Toshiro Kobori), in the presence of 1 mM dNTPs and 0.1 M DTT for 90 minutes at 32° C. Next, samples were stained with antibody against βIII-tubulin, to stain neurons, for 1 hour at RT. After washing, samples were incubated with Cy5-oligonucleotide probe to label amplified DNA and secondary anti-rabbit antibody conjugated with Alexa488. For the minimal (Min) and Maximal (Max) staining control only MINUS probe antibodies were used and the incubation with streptavidin was skipped. For the Max control Biotin-PLUS was added after the ligase incubation. Images were taken using a Zeiss LSM confocal microscope (Zeiss).
- Lumbar DRGs were homogenized using M-PER mammalian Extraction buffer (Pierce) supplemented with phosphatase and protease inhibitor cocktails (Pierce). Protein concentration was determined using the Bradford assay (Bio-Rad). Kinase activity profiling was performed using the Tyrosine Kinase PamChip® (PTK) Array and the Serine/Threonine Kinase PamChip® (STK) Array for Pamstation® 12 (PamGene International B.V.). For the PTK arrays 7.5 μg of protein lysate per array were used while for the
STK Arrays 2 μg of protein lysate per array were used. Image quantification and statistical analysis were performed using BioNavigator® Software (PamGene International B.V.). Upstream kinase analysis was performed using BioNavigator® Software with peptide-kinase mapping using Kinexus phosphonet enrichment files (www_phosphonet.ca/). Kinome tree illustration was constructed using data from the interactive PamGene BioNaviagor Upstream Kinase Tool (www_kinhub.org/kinmap/index.html). For pathway analyses peptides found to be significantly differentially phosphorylated (p<0.05) between IL4-10 and the combination of the individual cytokines were subjected to pathway analysis using the GeneGo pathway analysis package - RNA libraries were prepared with the poly A selection method followed by multiplexing and sequencing on the Illumina NextSeq500@ platform in a 1×75 bp single-read and 350 million reads per lane (Utrecht Sequencing Facility). All samples passed the read quality checks performed using FastQC (Andrews S (2010) FastQC: a quality control tool for high throughput sequence data. Available online at: www_bioinformatics.babraham.ac.uk/projects/fastqc.). The sequencing reads from each sample were aligned to the recent reference human genome GRCh38 build 79 assembly from Ensembl (Genome Reference Consortium Human Build 38) using STAR aligner (Cunningham F, et al. (2015) Ensembl 2015. Nucleic Acids Res 43(Database issue):D662-669; Anders S, Pyl P T, & Huber W (2015) HTSeq—a Python framework to work with high-throughput sequencing data. Bioinformatics 31(2):166-169). Gene expression data for the annotated genes was generated using HTSeq-count (Anders S, Pyl PT, & Huber W (2015) HTSeq—a Python framework to work with high-throughput sequencing data. Bioinformatics 31(2):166-169). The samples exhibited batch effect due to different days of isolation and library preparation. The batch effect was corrected using R package RUVSeq (Risso D, Ngai J, Speed T P, & Dudoit S (2014) Normalization of RNA-seq data using factor analysis of control genes or samples. Nat Biotechnol 32(9):896-90). Differential gene expression analysis and variance-stabilizing transformation (to obtain normalized read counts) were performed using R/Bioconductor package DESeq2 (Love M I, Huber W, & Anders S (2014) Moderated estimation of fold change and dispersion for RNA-seq data with DESeq2. Genome Biol 15(12):550).
- To identify whether sensory neurons are able to respond to regulatory cytokines, it was analyzed which receptors for regulatory cytokines are expressed by sensory neurons and glial cells. RNAseq data of receptors for IL10, IL4, IL13, and TGFβ1/2 in the dorsal root ganglia and spinal cord were extracted from the data base by Ray et al. (Pain 2018; 159:1325-1345) as available on www_utdallas.edu/bbs/painneurosciencelab/sensoryomics/drgtxome/?go. RNA sequencing revealed expression of receptors for IL10, IL4, IL33, TGFβ1 and TGFβ2 in the dorsal root ganglia and spinal cord of human and mouse (
FIG. 1 ; data are expressed as transcripts per million). - Next, expression of the alpha chain of both cytokine receptors, IL4R (IL4Rα) and IL10R (IL10Rα) in vivo in mice was studied. IL10Rα was expressed in almost all sensory neurons of the DRG, whilst IL4Rα is expressed in subsets of sensory neurons in the DRG (
FIG. 2A ). In culture, both IL4Rα and IL10Rα are expressed in NF200-, peripherin-expressing neurons and non-peptidergic 1B4+ neurons, often by the same cells. - Intrathecal administration is a well-known method to deliver drugs and other compounds in the direct environment of cells in the dorsal root ganglion and spinal cord. To test the requirement of IL4Rα expression by sensory neurons for the analgesic activity of IL4R-IL10R cross-linking compound, the inventors used intrathecal administration of antisense oligodeoxynucleotides (asODN) targeting IL4Rα mRNA. Three daily intrathecal injections of IL4Rα asODN significantly reduced IL4Rα mRNA and protein expression in the DRG by ˜70% compared to mismatched (mm) ODN-treated animals (
FIG. 2B ). IL4-10 fusion protein was used to cross-link IL4R and IL10R. Intrathecal injection of IL4-IL10 fusion protein (1 μg) at 6 days after the induction of persistent inflammatory pain completely inhibited carrageenan induced mechanical and thermal hyperalgesia in mice treated with mmODN confirming the potent analgesic properties of crosslinking IL4R and IL10R. It is to be noted that cross linking IL4R and IL10R may not completely abolish ability to detect sensory stimuli, but rather normalizes aberrant pain sensation. IL4Rα knockdown in the DRG markedly reduced the analgesic effect of the IL4R-IL10R cross-linking compound compared to animals treated with mmODN (FIGS. 2C and 2D ). Knockdown of IL4Rα during established carrageenan-induced hyperalgesia did not affect the magnitude of mechanical hypersensitivity. - Nav1.8+ sensory neurons mediate inflammatory pain (Abrahamsen et al. Science. 2008 Aug. 1; 321(5889):702-5). To identify the role of IL10Rα expression in the analgesic properties of the IL4R-IL10R cross-linking compound, IL10Rα was selectively ablated in Nav1.8+ neurons (
FIG. 2E ). The course of carrageenan-induced persistent inflammatory hyperalgesia was indistinguishable between wild-type and Nav1.8-IL10R−/− animals. - Intrathecal injection of the IL4R-IL10R crosslinking compound (1 μg) at
day 6 after induction of inflammatory pain attenuated thermal and mechanical hyperalgesia in wild type animals (FIGS. 2F and 2G ). In contrast, deletion of IL10Rα in Nav1.8+ nociceptors partially ablated the analgesic effect of the IL4R-IL10R cross-linking compound (FIGS. 2F and 2G ), indicating that nociceptor IL10Rα may be required in part for the pain inhibiting effects of IL4R-IL10R cross-linking compound. - Since both receptors are required for full analgesic effect of cross-linking IL4R and IL10R, the inventors next considered if ablation of both receptors in sensory neurons would completely prevent the analgesic actions of the IL4R-IL10R cross-linking compound. To that end, IL4R expression was knocked down in Nav1.8-IL10R−/− mice with intrathecal IL4Rα asODN injections. Knockdown of both IL4Rα and IL10Rα itself does not affect the course of persistent inflammatory pain. Importantly, knockdown of both IL4Rα and IL10Rα expression in the DRGs completely prevented resolution of pain by the IL4R-IL10R cross-linking compound (
FIGS. 3A-D ). - An increase of spinal immediate-early gene c-Fos expression can be used as a proxy of spinal neuronal activation in the dorsal horn of the spinal cord. At
day 7 after intraplantar carrageenan injection the number of c-Fos positive neurons in the superficial layers of the dorsal horn was significantly increased compared to naive animals (FIG. 3C ). Intrathecal administration of IL4-10 fusion protein significantly reduces the number of dorsal horn spinal cord c-Fos positive neurons. Knockdown of IL4Rα and IL10Rα in sensory neurons completely prevents IL4R-IL10R cross linking compound mediated attenuation of the c-Fos expression (FIG. 3C ). Overall this indicates that both IL4Rα and IL10Rα in sensory neurons are required for the full inhibition of persistent inflammatory pain resulting from cross-linking IL4R and IL10R. - The potential of cross-linking IL4R and IL13R to inhibit pain was investigated in chemotherapy-induced neuropathy models. Mice received 4 injections of paclitaxel (8 mg/kg) every other day from
day 0 to 6. Paclitaxel induced mechanical hyperalgesia that started on the first day after the first injection and that persisted at least 3 weeks after chemotherapy-treatment was stopped. Two days after the last paclitaxel injection, mice were injected intrathecally with 3 different doses of IL4-13 fusion protein (0.3, 1 and 3 μg/mouse) to cross-link IL4R and IL13R on cells in the dorsal root ganglion and the spinal cord (FIG. 4A ). An almost normalization of mechanical hyperalgesia lasting for at least a week was observed, demonstrating the potential of cross-linking IL4R and IL13R for long-lasting resolution of chemotherapy-induced polyneuropathy. Importantly, cross-linking IL4R and IL13R also reduced paclitaxel-induced intra-epidermal nerve fibre loss in the paw skin (FIG. 4B ), demonstrating that this intervention prevents neuronal damage in vivo. - To confirm that ross-linking IL4R and IL13R provides neuroprotection against a broader spectrum of chemotherapy-induced polyneuropathy, toxic neuropathy was also induced in mice using a platinum-based chemotherapeutic drug, oxaliplatin. Two cycles of 5 times a daily injection of oxaliplatin, separated by 5 days without intraperitoneal injection, induced mechanical allodynia that persisted for at least 3 weeks (
FIG. 4C ). Intrathecal injection of IL4-13 fusion protein on the second day after the last oxaliplatin injection reduced mechanical allodynia significantly for 4 days (FIG. 4C ). Intrathecal injection of either wild-type IL4 or wild-type IL13 transiently inhibited oxaliplatin-induced mechanical allodynia for about 1 day, which effect was significantly shorter than that of cross-linking IL4R and IL13R by the fusion protein. - Pro-inflammatory mediators sensitize sensory neurons for noxious and innocuous stimuli. To test whether cross-linking of IL4R and IL10R inhibits inflammatory mediator-induced sensitization of capsaicin-induced calcium responses in sensory neurons, cultured neurons were treated with TNF (50 ng/ml) with and without IL4-10 fusion protein, which was used to cross-link IL4R and IL10R (100 ng/ml, 3 nM). TNF significantly increased the magnitude of capsaicin-induced calcium influxes compared to untreated cells (
FIG. 5A-C ). Co-treatment with IL4-10 fusion protein completely prevents the sensitization of capsaicin-evoked calcium influx by TNFα. In a control experiment, it was excluded that IL4-10 fusion protein affects capsaicin-induced calcium responses in non-sensitized neurons (not shown). Similarly, cross-linking IL4R and IL10R inhibits PGE2-induced sensitization of capsaicin-induced calcium responses (FIG. 5D-F ), without affecting normal capsaicin-induced calcium fluxes (not shown). This indicates that cross-linking IL4R and IL10R prevents neuronal sensitization by inflammatory mediators. - To identify whether the inhibitory effects of IL4-10 fusion protein on neuronal sensitization requires both cytokine binding moieties, separate receptor blocking antibodies were added. Blocking either IL4R or IL10R slightly reduced IL4-10 fusion protein-induced inhibition of TNFα-induced sensitization of capsaicin evoked calcium responses. Interestingly, blocking both IL4R and IL10R receptors completely abrogates inhibition of neuronal sensitization induced by IL4-10 fusion protein (
FIG. 5G ). - Next the inventors considered to what extent cross-linking IL4R and IL10R to normalize neuronal sensitization by inflammatory mediators is superior to those of the combination of the wild-type cytokines. IL4-10 fusion protein dependently inhibits TNFα-induced sensitization of capsaicin-evoked calcium influx. At a concentration of 3 nM, it completely reversed TNFα-induced sensitization, whilst the combination of individual cytokines at the highest dose tested (30 nM) inhibited the TNFα-induced sensitization to a maximum of 50%. This indicates that cross-linking IL4R and IL10R has a superior potency over the combination of wild-type IL4 and IL10 to reduce neuronal sensitization by inflammatory mediators.
- Next, the inventors investigated whether such unique effects of crosslinking IL4R and IL10R on neurons also could be found for cross-linking IL4R with IL13R. To evaluate this, mouse sensory neurons were cultured in presence of oxaliplatin with or without IL4-13 fusion to cross-link IL4R and IL13R, or equimolar concentrations of wild-type IL4 and IL13 protein. Neurite length was measured to assess neurotoxicity. Oxaliplatin had a significant negative effect on neurite length when compared to the control group (
FIG. 6 ). IL4-13 fusion protein completely protected against oxaliplatin-induced neurotoxicity, whilst the combination of equimolar concentrations of wild-type IL4 and IL13 did not. An additional assay with two IL4-IL13 fusion proteins showed similar - Thus, these data together demonstrate that cross-linking IL4R and IL10R, or IL4R and IL13R induces effects in neurons that normalize the hypersensitization by inflammatory mediators and protect the cells against damage. Importantly, these effects are unique to cross-linking involved receptors, since they are not induced by combinations of the wild-type cytokines tested at concentrations equimolar to that of the fusion proteins.
- To further investigate the mechanisms of the unique effects of IL4-10 fusion protein and IL4-13 fusion proteins, the inventors decided to analyse the cellular processes induced by IL4-10 fusion protein in more detail. The inventors hypothesized that the IL4-10 fusion protein causes heterologous clustering of IL4R and IL10R, thereby inducing unique signalling in sensory neurons, i.e. signalling that is not induced by wild-type cytokines, and even not by the combination of wild-type cytokines. First, cross-linking of IL4R and IL10R by IL4-10 fusion proteins on neurons was demonstrated. Sensory neurons were incubated IL4-10 fusion protein or the combination of the respective interleukins for 15 minutes in vitro followed by a proximity ligation assay (PLA) to assess clustering of IL4R and IL10R. This method enables the inventors to detect clustering of the 2 receptors within a 51 nm range. IL4-10 fusion protein (100 ng/ml, 3 nM) treatment indeed cluster IL4R and IL10R receptors in sensory neurons, whilst receptor clustering did not occur after treatment with equimolar concentration of the combination of the respective cytokines or after vehicle (
FIG. 7 ). Clustering of IL4R and IL10R is specifically induced by the fusion protein as clustering of IL4R and another highly expressed membrane protein, CD200, was not observed (data not shown). - The ability of IL4-10 fusion protein to cross-link IL4 and IL10 receptors raises the possibility that this drives unique downstream signaling events. To elucidate downstream signaling in sensory neurons in an unbiased manner, the inventors performed PAMgene kinase activity profiling to assess global protein tyrosine kinases (PTK) and serine/threonine kinases (STK) activity in homogenates of lumbar DRGs of mice with persistent inflammatory pain after administration of IL4-10 fusion protein. Kinomic profiles were assessed at 30, 60 and 240 minutes after intrathecal administration with either the anti-IL4R-IL10R bispecific antibody, the combination of cytokines or PBS. Analyses of the 3 different time points indicated that the most prominent changes in kinome profiles were found at 60 minutes after intrathecal injection, whilst differences are less pronounced at the other time points examined (
FIG. 8 ). Analyses of the peptides that are differentially phosphorylated by PTK present in the DRG homogenates at 60 minutes after treatment shows that in total 38 peptides were differentially phosphorylated when in IL4-10 fusion protein-treated mice compared to vehicle treated mice. Cross-linking IL4R and IL10R induces stronger phosphorylation of 5 peptide substrates for PTKs that were also activated by the combination of cytokines (FIG. 8A ). Interestingly, 33 peptides are only phosphorylated by homogenates from mice treated with IL4-10 fusion protein and from mice treated with the combination of IL4 and IL10, indicating that anti-IL4R-IL10R bispecific antibody activates a unique set of PTK (FIG. 8A ). Peptides were identified that exhibited different phosphorylation between IL4-IL10 treatment and treatment with the combination of unlinked cytokines (FIG. 8B ). Next the inventors evaluated the differentially phosphorylated STK peptides. Intriguingly DRG homogenates of mice treated with the combination of the cytokines phosphorylate 14 STK peptides to a lesser extent compared to vehicle-treated mice, whilst the homogenates from mice treated with IL4-10 fusion protein did not exhibit differences for most peptides, and induced increased phosphorylation in some (FIG. 8C ). Peptides were identified that exhibited different phosphorylation between IL4-IL10 treatment and treatment with the combination of unlinked cytokines (FIG. 8D ). These data indicate that both PTK and STK activity are differentially regulated upon cross-linking of IL4R and IL10R in vivo compared to the effects of the combination of wild-type cytokines. Each of the peptides present in the kinase activity array can be substrates for different kinases, and one kinase or family of kinases can phosphorylate different peptides. To predict the putative upstream kinases activated specifically by cross-linking IL4R and IL10R, the differential phosphorylation profiles are loaded into PhosphoNET. These analyses predict that several kinases are activated at 60 minutes after injection based on the observed phosphorylation patterns of the peptides (FIG. 8E-H ). The inventors identified kinases, including the PTK platelet-derived growth factor receptor A (PDGFRa), KIT, fms like tyrosine kinase 3 (FLT3), MER or RET tyrosine kinases; the calcium calmodulin kinases (CAMK) such as CHK2, CAMK4 or DCAMKL2; AMPK, JAK1, and the Protein kinase A/G/C family such as AKT3, PKCb or NDR1/2. Examples of differentially activated kinases between IL4-IL10 and the combination of unlinked cytokines are provided inFIG. 8G andFIG. 8H , and include the PTKs KIT, PDGFRA, FER, MET and JAK1, and the STKs AKT3, LATS2, NDR2 or CAMK2. Pathway analysis of these predicted differentially can activate kinases indicates that the most active cellular processes induced by anti-IL4R-IL10R bispecific antibody treatment are mapped to immune responses, altered transcription, cell adhesion or cell cycle. The top 5 kinase substrates ranked by occurrence in the top 50 of the pathway analysis were NAPDH oxidase P47-phox, p120GAP, Rb protein, CDC25A and ZAP70. Overall this indicates that cross-linking IL4R and IL10R drives different signalling pathways, differential activation of kinases, different phosphorylation of kinase substrates, and a different kinomic profile compared to vehicle and compared to treatment with equivalent amounts of unlinked cytokines. For example, the activation of sets of kinases not activated by the combination of IL4 and IL10 and drives stronger activation of several kinases also activated by the combination of IL4 and IL10. - To further explore the potential capacity of cross-linking IL4R and IL10R to elicit downstream effects that differ from that of the combination of IL4 and IL10, the inventors performed RNA sequencing of DRGs, six hours after a single intrathecal injection of IL4-10 fusion protein, the combination of IL4 and IL10, or PBS alone in mice with persistent nociceptive pain. Principal component analysis (PCA) indicates that 75% of the variance in gene expression can be explained by the first two principal components. The first principal component captures 55% variance of the data and separates the mice with cross-linking of IL4R and IL10R from mice that received vehicle or the combination of unfused cytokines, while the second principal component may capture 20% variance of the data and separates vehicle treated animals, indicating that IL4-10 fusion protein induces different transcriptome changes (
FIG. 9A ). Hierarchical clustering of the top 500 differentially regulated genes showed that based on their transcriptional profile the individual animals clustered based on the three different treatments (FIG. 9B ). Thus, cross-linking IL4R and IL10R induces a different transcriptional profile compared to mice treated with IL4 and IL10 or vehicle. Treatment of mice with the combination of IL4 and IL10 resulted in 4905 genes differentially expressed (FDR corrected p-value<0.05) compared to those injected with PBS (FIG. 9C ). KEGG Pathway analysis indicated that these genes aggregate in pathways affecting TLR signaling, oxidative phosphorylation, ribosomal proteins and lipid metabolism. In the mice injected intrathecally with IL4-10 fusion protein, 3995 genes are differentially expressed (FDR corrected p-value<0.05) compared to those injected with vehicle. Pathway analysis of the differentially expressed genes reveals that neuronal-related genes such as axon guidance and calcium signaling or energy production such as oxidative phosphorylation are downregulated in mice upon cross-linking IL4R and IL10R. Moreover, genes involved in inflammatory pathways like interferon signaling, antigen processing and presentation, complement and interleukin signalling are affected. Interestingly, when genes induced by cross-linking of IL4R and IL10R are compared with those induced by the combination of the cytokines, 3025 genes are differentially expressed (FIG. 9C ). Analysis of these genes indicates that the expression of 1650 genes is increased, whilst 1375 are downregulated upon cross-linking IL4R and IL10R, as compared to the combination of cytokines. Importantly, 1675 genes are uniquely regulated by IL4-10 fusion protein. From these uniquely regulated genes, the expression of 981 genes is increased by the fusion protein, whilst 694 are downregulated. Pathway analysis of the genes that are differentially expressed upon crosslinking of IL4R and IL10R as compared to the transcriptome of animals receiving the combination of wild-type IL4 and IL10 indicates that these genes belong to pathways including cytokine signaling, neurotrophin signaling, and pathways affecting innate and adaptative immune system indicating potential DRG-infiltrating immune cells (FIG. 9E ). Additional analysis of upstream kinases based on KEGG pathways indicated that signalling pathways including cytokine and chemokine signaling, NOD-like receptor signaling or JAK-STAT signaling were affected (FIG. 9F ). Focal and cell adhesion molecules and pathways affecting innate and adaptive immune system, such as TLR, T and B cells receptor pathways were also affected, which may reflect potential DRG-infiltrating immune cells. Overall, RNAseq data demonstrates that cross-linking IL4R and IL10R induces a unique transcriptome change as compared to animals treated with the combination of IL4 and IL10. - Based on the data obtained from PAMgene analysis, KIT, PDGFRA, FER, MET and JAK1 were identified as the 5 highest ranking potential Tyrosine kinases that could be linked to the superior effects of IL4-10. Whether IL4-10 differentially activates JAK1 in sensory neurons in vitro by was investigated by determining phosphorylation of JAK1 after stimulation of sensory neurons in vitro with IL4-10 or equimolar concentration of IL4 and IL10 for 10, 30 or 60 minutes. After 10 minutes, IL4-10 significantly increased pJAK1 in sensory neurons compared to vehicle and IL4+IL10 (
FIG. 10A ). At 30 minutes after stimulation both IL4-10 and IL4+IL10 increased pJAK1. To investigate whether JAK1 signaling is required for the superior IL4-10 mediated pain inhibition, carrageenan-injected animals were treated with Ruxolitinib (JAK1/2 inhibitor) for 3 consecutive days, starting one day before intrathecal administration of IL4-10. Ruxolitinib almost completely prevented the IL4-10-induced inhibition of thermal hyperalgesia (FIG. 10B ) and shortened the duration of IL4-10-induced inhibition of mechanical (FIG. 10C ) hyperalgesia. Inhibition of JAK1 with Ruxolitinob did not affect IL4+IL10-mediated inhibition of hyperalgesia. To verify whether other kinases identified based on PAMgene and RNAseq data (c-Kit, PDGFR or c-Met) also contribute to the pain-inhibiting effects of IL4-10, these were inhibited using Dasatinib (Kit inhibitor), Masitinib (Kit and PDGFR inhibitor) and JNJ-38877605 (c-Met inhibitor). Inhibition of c-Kit or combined inhibition of c-kit and PDGFR did not affect IL4-10-induced inhibition of thermal hyperalgesia (FIG. 10D ). In contrast, inhibition of c-Kit and c-Kit and PDGFR enhanced the IL4-10-induced reduction in mechanical hyperalgesia by IL4-10 (FIG. 10E ). Pharmacological inhibition of c-Met partially attenuated the pain-inhibiting effects of IL4-10 (FIG. 10 D, E). - These data suggest that pJAK1 and c-MET signaling contribute to the superior pain-alleviating effect of IL4-10.

The polypeptide constructs (e.g., fusion proteins) are designed in both orientations, e.g., with IL4 located on the C-terminal side of TGFβ2, or with IL4 located on the N-terminal side of TGFβ2. An affinity tag is added to the N-terminus and/or the C-terminus of each construct, and the constructs are produced by transient transfection of HEK293E cells as disclosed below.
- IL4-containing fusion proteins of the disclosure are produced by transient transfection of HEK293E cells. Cells are transfected with a pUPE expression vector containing a transgene coding one of the IL4-containing fusion protein sequences. To enable purification, a hexa-histidine affinity tag is cloned at the N-terminus of each IL4-containing protein. Six days post transfection, conditioned medium containing recombinant protein is harvested by low-speed centrifugation (10 minutes, 1000×g) followed by high-speed centrifugation (10 minutes, 4000×g).
- Proteins are purified via His-tag by Immobilized Metal Affinity Chromatography (IMAC). In short, the recombinant protein is bound to 0.5 ml Nickel Sepharose® excel at 20° C. Nickel Sepharose® excel containing bound protein is harvested by centrifugation and transferred into a gravity flow column. Non-specifically bound proteins are removed by washing the column with IMAC buffer (500 mM Sodium Chloride, 25 mM Tris, pH=8.2) containing 0 and 10 mM imidazol. The proteins are eluted with IMAC buffer containing 500 mM imidazol. Fractions of 2.5 ml are collected. Recombinant protein-containing fractions are pooled. Conditioned medium and the unbound IMAC fraction are analyzed by LabChip® capillary electrophoresis. The IMAC pool is concentrated to 2-4 ml using an
Amicon 10 kDa spin filter. Aggregates are removed by centrifugation (10 minutes 18000×g, 4° C.). - The proteins are purified further by gel filtration using a
Superdex200 16/600 column that has been equilibrated in PBS. Protein containing fractions are analyzed by LabChip® capillary electrophoresis and recombinant protein containing fractions are pooled. Protein pools are sterilized by filtration using a 0.22 μm syringe filter and the product stored in 1 ml vials at 80° C. - Protein assays: Protein concentration in batches is determined spectrophotometrically by measuring the absorbance at 280 nm (DropSense16, Trinean) and using a BCA (Thermo Scientific) protein assay.
- SDS-Page: Purified proteins are analysed on 12% polyacrylamide SDS-Page gels (Bio-Rad) and bands are visualized by InstantBlue® protein stain (Expedeon; Cambridge).
- Experiments are conducted to determine whether IL4-containing compounds (e.g., polypeptide constructs, fusion proteins) of the disclosure affect neuronal sensitization. Cultured neurons are treated with TNFα (50 ng/ml) with and without a compound (e.g., polypeptide construct, fusion protein) of the disclosure, (e.g., at approximately 3 nM). TNFα increases the magnitude of capsaicin-induced calcium influxes compared to untreated cells. Co-treatment with a compound (e.g., polypeptide construct, fusion protein) of the disclosure reduces the sensitization of capsaicin-evoked calcium influx by TNFα. Similar experiments are conducted to determine how sensitivity to PGE2 is affected. Additional experiments are conducted to determine whether the compound of the disclosure affects capsaicin-induced calcium responses in non-sensitized neurons. Constructs are identified that reduce neuronal sensitization by inflammatory mediators. For each polypeptide construct, controls are included to determine the effect of the individual cytokines, and the combination of the cytokines, that the compound (e.g., polypeptide construct, fusion protein) comprises. Constructs are identified that exhibit superiority over individual cytokines, and the combination of cytokines.
- Experiments are conducted to determine whether compounds (e.g., polypeptide constructs, fusion proteins) of the disclosure crosslink cytokine receptors. Sensory neurons are incubated with polypeptide constructs of the disclosure or the combination of the respective cytokines for 15 minutes in vitro followed by a proximity ligation assay (PLA) to assess receptor clustering. Constructs are identified that induce crosslinking of cytokine receptors.
- Experiments are conducted to determine whether compounds (e.g., polypeptide constructs, fusion proteins) of the disclosure elicit distinct kinase activity profiles compared to the combination of unlinked cytokines.
- Persistent inflammatory pain is induced in mice as using carrageenan as disclosed herein. PAMgene kinase activity profiling is performed to assess global protein tyrosine kinases (PTK) and serine/threonine kinases (STK) activity in homogenates of lumbar DRGs of mice after administration of protein constructs of the disclosure, or their component cytokines in combination. Kinomic profiles are assessed at 30, 60 and 240 minutes after intrathecal administration with either the polypeptide construct, the combination of cytokines, or PBS. To predict the putative upstream kinases, differential phosphorylation profiles are loaded into PhosphoNET, and pathway analysis is conducted. Compounds (e.g., polypeptide constructs, fusion proteins) are identified that elicit different kinomic profiles to the combination of their component cytokines. Differentially phosphorylated substrates, differentially active upstream kinases, and differentially active pathways are identified.
- Experiments are conducted to determine whether compounds (e.g., polypeptide constructs, fusion proteins) of the disclosure elicit distinct transcriptomic profiles compared to the combination of unlinked cytokines.
- Persistent inflammatory pain is induced in mice as using carrageenan as disclosed herein. RNA sequencing of DRGs is done six hours after administering a compound of the disclosure, or their component cytokines in combination. Principal component analysis (PCA) and hierarchical clustering of the top differentially regulated genes, and pathway analysis are conducted. Compounds (e.g., polypeptide constructs, fusion proteins) are identified that elicit different transcriptomic profiles to the combination of their component cytokines. Differentially expressed genes and pathways are identified.
- Assays are conducted to assess whether the IL4-containing compounds (e.g., polypeptide constructs, fusion proteins) can treat, for example, pain, chemotherapy-induced polyneuropathy (CIPN) pain, nerve fiber loss, and allodynia. The assays are conducted for any compound (e.g., polypeptide construct, fusion protein) disclosed herein, for example, polypeptide constructs comprising an IL4 and a regulatory cytokine, e.g., an IL10/IL4, IL13/IL4, IL27/IL4, IL33/IL4, TGFβ1/IL4, TGFβ2/IL4, or IL4/IL4 of the disclosure.
- To induce transient chemotherapy-induced polyneuropathy (CIPN), paclitaxel (2 mg/kg, Cayman Chemical Company) is injected intraperitoneally into C57BL/6 mice on
days day - Noxious mechanical sensitivity in the hind paws is measured using von Frey hairs (Stoelting, Wood Dale, USA). Results are expressed as the 50% paw-withdrawal threshold using the up-and-down method. Thermal hyperalgesia is assessed by determining the heat withdrawal latency times using the Hargreaves test (IITC Life Science). In some experiments the length of intraepidermal nerve fibers in the paw skin at
day 15 is determined by immunofluorescent staining of skin biopsies with the neuronal marker PGP9.5. All experiments are performed in a blinded manner. - IL4-containing compounds (e.g., polypeptide constructs, fusion proteins) are administered to mice, e.g., via intrathecal injection under light isoflurane/O2 anaesthesia, or by another route as disclosed herein. The ability of IL4-containing compounds (e.g., polypeptide constructs, fusion proteins) of the disclosure to inhibit paclitaxel or oxaliplatin-induced neuropathy, carrageenan-induced inflammatory hyperalgesia, and intra-epidermal nerve fibre loss, is determined and compared to the combination of unlinked cytokines for each construct.
- Assays are conducted to assess whether the IL4-containing compounds (e.g., polypeptide constructs, fusion proteins) possess neuroprotective properties, e.g., inhibit paclitaxel-induced reduction of neurite length. The assays are conducted for any compound (e.g., polypeptide construct, fusion protein) disclosed herein, for example, polypeptide constructs comprising an IL4 and a regulatory cytokine, e.g., an IL13/IL4, IL10/IL4, IL13/IL4, IL27/IL4, IL33/IL4, TGFβ1/IL4, TGFβ2/IL4, or IL4/IL4 of the disclosure.
- Culture of DRG neurons: DRGs are cultured as described previously (Nat. Commun. 4, 1682 (2013)). Briefly, DRGs are dissected and placed on ice-cold dissection medium (HBSS w/o Ca2+ and Mg2+, 5 mM HEPES, and 10 mM glucose). After dissection, axons are cut and dissection medium is replaced by filtered enzyme mix (HBSS without Ca2+ and Mg2+, 5 mM HEPES, 10 mM glucose, 5 mg/ml collagenase type XI (Sigma), and 10 mg/ml Dispase (Gibco)). The DRGs are incubated in enzyme mix for 30 minutes at 37° C. and 5% C02. Subsequently, enzyme mix is inactivated with heat-inactivated fetal bovine serum (FBS, Sigma). Cells are cultured in Dulbecco's modified Eagle's medium (Gibco) containing 10% FBS (Gibco), 2 mmol/L glutamine (Gibco), 10,000 IU/ml penicillin-streptomycin (Gibco) on poly-L-lysine (0.01 mg/ml, Sigma) and laminin (0.02 mg/ml, Sigma)-coated glass coverslips in a 5% CO2 incubator at 37° C. Cells are used the following 1-2 days.
- Treatments and neurite length measurement: After 24 h in culture, DRG neurons are treated with Paclitaxel (1 μM) alone, or in the presence of different concentrations of IL4 compounds (e.g., polypeptide constructs, fusion proteins) (e.g., 0.12 nM, 0.6 nM, or 3 nM), or equimolar doses of the individual cytokines that are present in the constructs for 24h. Neurites are visualised using p3-tubulin staining, whilst the number of sensory neurons is determined using NeuN staining. Pictures are taken and for each picture, the neurite length per sensory neuron is determined. The neurite length is averaged to a single value for each animal and condition. The percentage inhibition of paclitaxel-induced neurite length loss per mouse culture of 1 mouse is calculated according the following formula ((μcontrol−μpaclitaxel)−(μcontrol−Xcytokine))/(μcontrol−μpaclitaxel)*100 (where p is the average neurite length per neuron averaged over all samples and X is the neurite length of each individual sample).
- β3-tubulin and NeuN staining: cells are fixed in 4% PFA for 10 minutes, permeabilized with PBS with 0.05% Tween-20, followed by incubation in blocking buffer (1% BSA and 5% Normal donkey serum in PBS with 0.05% Tween-20 and 0.01% triton) for 1 hour. Cells are incubated with rabbit anti-β3 tubulin (Anti-beta III Tubulin antibody-Neuronal Marker, ab18207, 1:1500, Abcam, Cambridge, UK) and NeuN (Anti-NeuN Antibody clone A60, MAB377, 1:500) Sigma Aldrich (Merck), Darmstadt, Germany) overnight at 4° C., followed by washes and incubation with AF488-conjugated donkey anti-rabbit and 568-conjugated donkey anti-mouse secondary antibodies (Thermofisher, 1:500) followed by DAPI (1:5000, Sigma) staining before sections are mounted on slides with FluorSave reagent (Millipore).
- Images are taken using an Olympus IX83 microscope (Olympus). Pictures are analysed using CellSens software (Olympus) and ImageJ (NIH), using the NeuralNetrics macro kindly provided by prof. dr. Winnok de Vos (University of Antwerp) (Pani G, De Vos W H, Samari N, de Saint-Georges L, Baatout S, Van Oostveldt P, et al. MorphoNeuroNet: An automated method for dense neurite network analysis. Cytom Part A. 2014 February; 85(2):188-99). Other plugins used are Olympus Viewer plugin (Olympus). Cell sense software is used to automatically count number of neurons based on NeuN staining. Neurite length is determined using the NeuralNetric macro in ImageJ (Fuij).
- Animals: All animal experiments were performed in accordance with international guidelines and with prior approval from the University Medical Center Utrecht experimental animal committee. Experiments were conducted with 8-14 weeks old male and female wild type (WT) C57BL/6 mice.
- Paclitaxel-induced CIPN: At
day injection 40 μl/10 g of bodyweight. Atday 8, animals received i.t. injections of: IL4/IL13 fusion protein (0.3 μg), IL4+IL13 (0.15 μg each) or Vehicle. - Drugs and administration: The IL4/IL13 was produced by transient transfection of HEK293F cells with the pcDNA3.1-neo expression vector (Invitrogen; Carlsbad, Calif.) with dual CMV promotor. The vector contained two transgenes: cDNA coding for IL4/IL13 fusion protein and cDNA coding beta-galactoside-2, 3-sialyl-transferase to optimize glycan capping with sialic acid. The IL4/IL13 contained a 6-His tag at the N terminus and was purified through HIS-Select Nickel Affinity gel (Sigma). IL4/IL13 concentrations were determined with an IL4 ELISA kit (IL-4 Pelipair ELISA kit; Sanquin) and Bicinchoninic Acid Protein Assay (BCA Pierce Protein Assay Kit, ThermoFisher Scientific). Intrathecal (i.t.) injections of different compounds (5 μl/mouse) were performed as described before (
J Neurosci 30, 2138-2149, 2010) under light isoflurane/O2 anesthesia. The IL4/IL13 (0.3 μg/mouse) or equimolar doses (0.15 μg each/mouse) of recombinant human HEK-produced IL4 (Sigma) and IL13 (2bsciences) were injected intrathecally atday 8 after the first paclitaxel injection. - Kinase Activity Profiling: Animals were killed an hour after intrathecal injection of the IL4/IL13 fusion protein, IL4+IL13 or vehicle, followed by immediate DRG isolation. Lumbar DRGs were homogenized using M-PER mammalian Extraction buffer (Pierce) supplemented with phosphatase and protease inhibitor cocktails (Pierce). Protein concentration was determined using the Bradford assay (Bio-Rad). Kinase activity profiling was performed using the Tyrosine Kinase PamChip® (PTK) Array for Pamstation®12 (PamGene International B.V.). For the PTK array, 7.5 μg of protein lysate per array was used. Image quantification and statistical analysis were performed using BioNavigator® Software (PamGene International B.V.). Upstream kinase analysis was performed using BioNavigator® Software with peptide-kinase mapping using Kinexus phosphonet enrichment files (www_phosphonet.ca/).
- To elucidate downstream signaling in sensory neurons in an unbiased manner, PamGene kinase activity profiling was performed to assess global protein tyrosine kinases (PTK) activity in homogenates of lumbar DRGs isolated from mice with persistent paclitaxel-induced CIPN after IL4/IL13 fusion protein, IL4+IL13 (combination of unlinked cytokines), and vehicle administration. Kinomic profiles were assessed at 60 minutes after intrathecal administration of the IL4/IL13 fusion protein, the combination of cytokines, or vehicle (PBS). Naive mice (i.e. not treated with paclitaxel or IL4/IL13 fusion protein) were also included.
-
FIG. 11 illustrates peptides that were differentially phosphorylated based on one-way ANOVA analysis between IL4/IL13, IL4+IL13, and vehicle-treated mice compared to naive mice (untreated; no paclitaxel, no intrathecal injection). Black indicates no significant changes, while color indicates decreased phosphorylation. Analyses of the peptides that were differentially phosphorylated by PTK in the DRG homogenates of IL4/IL13-treated versus IL4 plus IL13-treated mice and vehicle-treated mice, indicated that in total 19 peptides were uniquely phosphorylated upon treatment with the fusion protein. - Analyses of the peptides that were differentially phosphorylated by PTK in the DRG homogenates of IL4/IL13-treated male and female mice versus IL4 plus IL13-treated mice, indicated that in both sexes the activity of different kinases is differentially affected by the IL4/IL13 compared to the combination of cytokines (
FIG. 12 andFIG. 13 ). - In DRGs from female mice treated with the IL4/IL13 fusion protein, the activity of several kinases was reduced when compared female mice treated with the combination of IL4 and IL13 (
FIG. 12 ). The graph shows the predicted upstream kinases inferred from the differentially phosphorylated peptide substrates on the PamChips® identified by unpaired t-test comparison between samples from IL4/IL13 fusion protein-treated females and IL4+IL13-treated females (n=3 animals per group). The top 5 predicted putative kinases affected (according to summation of sensitivity and specificity score) were: ITK, RET, TYK2, FER and ERBB4. - In male mice, unique kinase activity was predominantly increased (
FIG. 13 ). The graph shows predicted upstream kinases that can be inferred from the differentially phosphorylated peptide substrates on the PamChips® identified by unpaired t-test comparison between samples from IL4/IL13 fusion protein-treated males and IL4+IL13-treated males (n=3 animals per group). The top 5 predicted putative kinases affected were: LTK, RYK, ALK, AXL and BLK. - These data show that IL4/IL13 uniquely regulates sets of kinases compared to the combination of unlinked IL4 plus IL13.
- In the present work the inventors consider that the coupling of IL4R binding region and a cytokine receptor (e.g., IL10R, IL13R, IL27R, IL33R, TGFβ1R, TGFβ2R) binding region in a single molecule/protein creates a novel molecule that is able to target regulatory cytokine receptors in sensory neurons to trigger unique signalling pathways (e.g., pain resolution pathways) that are not activated by the combination of both wild-type cytokines. Sensory neurons and other cells in the dorsal root ganglion and spinal cord express functional cytokine receptors (e.g., IL4R, IL10R IL13R, IL10R, IL33R, TGFβ1R, and TGFβ2R), and cross-linking these receptors by a compound (e.g., polypeptide construct, fusion protein) or a bispecific antibody or any other compound that can bind at least two of these receptors in sensory neurons, can be used to stop, for example, chronic pain, either nociceptive, neuropathic or combined nociceptive-neuropathic pain. Furthermore, this unique signalling induced by cross-linking of receptors of regulatory cytokines on neurons and glial cells, prevents neuronal damage.
