Definitions
- the invention relates in general to peptides that have the ability to bind interleukin 10 (IL-IO) and its applications.
- the invention relates to peptides inhibiting the biological activity of IL-10 by its direct binding to IL-10, and its use in the treatment of clinical conditions or pathological alterations associated with expression of IL-10, in particular , with a high expression of IL-10.
- the immune response includes both a cellular response and a humoral response.
- the cellular response is mostly mediated by T lymphocytes, while the humoral response is mediated by B lymphocytes.
- Lymphocytes play important roles in the immune response, including directing cell death of virus-infected cells, the production of cytokines and antibodies, etc. Lymphocytes are also involved in acute and chronic inflammatory diseases.
- Cytokines are soluble proteins that mediate reactions between cells and that influence cell growth and differentiation. Cytokines exert their effects through binding to specific receptors which leads to the activation of specific transduction signals for these cytokines.
- Interleukin 10 is a pleiotropic cytokine produced by various cell types such as macrophages, monocytes, B cells and regulatory and Th2 type T cells.
- IL-10 is a cytokine with immunosuppressive and anti-inflammatory properties, regulates numerous myeloid and cellular lymphoid activities and directly inhibits the production of various inflammatory cytokines by T cells and NK cells ("Natural Killer").
- IL-10 was first described as a cytokine synthesis inhibitor factor (FISC) produced by Th2 cells that inhibited the production of proinflammatory cytokines such as interferon-gamma (IFN- ⁇ ), interleukin 1-alpha (IL-l ⁇ ), interleukin 1-beta (IL-l ⁇ ), interleukin 2 (IL-2) and tumor necrosis factor alpha (TNF- ⁇ ), by ThI cells .
- FISC cytokine synthesis inhibitor factor
- IL-IO has been shown to be able to inhibit ThI antigen-specific cell proliferation by reducing the ability of antigen presenting monocytes through deregulation of the expression of the main complex of histocompatibility (MHC) of the major class histocompatibility complex in these cells.
- MHC histocompatibility
- IL-IO has a strong inhibitory effect on the activation of ThI cells and on the production of proinflammatory cytokines led to the hypothesis that IL-10 was a potent immunosuppressant of cell-mediated immune responses.
- Other authors have proposed the use of this cytokine in the treatment of acute and chronic inflammatory processes as well as in autoimmune diseases. For these reasons, this cytokine has been used in several autoimmune diseases, such as psoriasis, rheumatoid arthritis and Crohn's disease. However, in other diseases, such as in infectious processes or in cancer, it has a negative effect, since it prevents the induction of ThI responses that would promote healing.
- IL-10 is expressed in abundance.
- This cytokine can be produced by Th2 cells as a result of stimulation with HCV antigens. It can also be produced by regulatory T cells (CD4 and CD8) that inhibit the development of ThI type effector antiviral cells.
- DC infected dendritic cells
- monocytes in contact with HCV proteins, produce more IL-10 than uninfected cells, which favors the development of Th2 responses and prevents virus elimination.
- IL-10 plays an important role
- tumor cells or tumor infiltrate cells can produce, among other molecules, IL-10, which impairs the functioning of DC. Inhibiting the proper functioning of DC in tumors would be one of the reasons why an antitumor response does not occur.
- IL-12 interleukin 12
- ThI response said inhibition of IL-10 It would be very useful both in certain antiviral therapies, such as chronic HCV infection, and in antitumor therapies, where it is desired to induce potent ThI responses.
- IL-10 Other strategies commonly used to inhibit the biological activity of IL-10 include either the use of specific neutralizing antibodies or the use of antisense oligonucleotides (oligos) of the gene encoding IL-10 that block its expression.

- phages consist of filamentous bacteriophages (M 13) that contain a peptide genetically fused to a virus coat protein, in this case attached to the N-terminal end of the coat protein pIII ( Figure 1).
- M 13 filamentous bacteriophages
- Figure 1 the phage has a 15 amino acid peptide on its surface in each of the 5 molecules of this protein that the phage has on its surface, while inside it contains the DNA encoding said peptide.
- the peptide coding sequence comes from a degenerate sequence in each of the 15 positions with the 20 natural amino acids. This allows the presentation of 1, IxIO 12 possible sequences of 15 amino acids in different phages.
- the physical relationship, I to I, between the peptide sequence and the DNA encoding it in the bacteriophage makes it possible to select, from a large number of variants, those sequences that specifically bind to IL-10. This process is performed using an in vitro selection protocol called "biopanning".
- biopanning an in vitro selection protocol
- the phage suspension titre calculated by spectrometry was 3.82 x 10 14 virions / ml and the number of infectious particles was 1.3 x 10 13 TU / ml.
- a fraction of this phage suspension was sequenced to verify that the amplification had not affected the diversity of the clones.
- the biopanning technique consists of the incubation of a set of phages, representatives (for practical purposes) of all 15 amino acid variants, in a streptavidin-blocked plate (10 ⁇ g / ml in 0.1 M NaHCO 3 , 2 hours at room temperature) to which biotinylated IL-IO is added.
- Biotinylated IL-10 is anchored to plaque through biotin-streptavidin interaction, which is correctly presented for interaction with peptides carried by phage.
- the IL-10 is contacted with the phage-borne peptides at a concentration of 3x10 4 viruses / ml and allowed to incubate for approximately 12 hours.
- the concentration of biotinylated IL-10 used to block the plates is gradually reduced in each round from 2.5 ⁇ g / ml to 0.02 ⁇ g / ml, and finally to 0.002 ⁇ g / ml.
- the phages selected in each round have an increasing degree of affinity for IL-10.
- phages that have been selected for their affinity for IL-10 are sequenced with primers, after being isolated by tetracycline resistance conferred by genetically modified phages after infecting E. coli cells. This allows to obtain the sequences of the peptides presented in the phages of a number of clones obtained from isolated colonies. The number of times a sequence is repeated, corresponding to a 15 amino acid peptide carried by each clone, of the total sequenced clones gives an idea of the degree of relative affinity that said 15 amino acid peptide has for IL-IO.
- each colony contains the genome of a single phage that corresponds to the sequence of a single peptide presented on its surface.
- the number of clones (colonies) of each sequence gives a relative idea of the degree of affinity between the peptides and IL-10, that is, the greater the number of clones, the greater the binding affinity.
- the degree of affinity does not correspond to the ability to block the activity of IL-10 since some of the most active peptides, eg, peptides identified as SEQ ID NO: 6 (P9) and SEQ ID NO: 17 (P23), provide 3 and 1 clones, respectively, while the peptide identified as SEQ ID NO: 6 (P9) and SEQ ID NO: 17 (P23), provide 3 and 1 clones, respectively, while the peptide identified as SEQ ID NO: 6 (P9) and SEQ ID NO: 17 (P23), provide 3 and 1 clones, respectively, while the peptide identified as SEQ ID NO: 6 (P9) and SEQ ID NO: 17 (P23), provide 3 and 1 clones, respectively, while the peptide identified as SEQ ID NO: 6 (P9) and SEQ ID
- SEQ ID NO: 2 which provides 29 clones, is much less active in the inhibition assay (Example 3). Although it is not desired to be linked to any theory, this issue could be explained on the basis that the most active peptide would probably block the binding of IL-IO to its receptor.
- sequences obtained were analyzed with the "trans ⁇ ate tool" program available on the Internet http://www.expasy.org/tools/dna.html that allows to deduce the amino acid sequences that were subsequently worked on. They sequenced a total of 143 clones, which allowed to identify 35 different peptides (P1-P35), of which 9 of said peptides (P3, P4, P6, Pl 1, P 12, P 17, P27, P28 and P30) were also found in other biopanning tests with other proteins, it was considered that they were not specific for IL-IO binding and, consequently, could be discarded. These nonspecific junctions may be due to interactions with some of the components present during the selection process (plastic, biotin, streptavidin, etc.) and / or phage surface proteins.
- ChIL-IO ChIL-IO
- hIL-10 inhibitors were developed taking into account the structure of the complex (h ⁇ L-10) - (hIL-10 receptor). In this structure there are two zones of alpha helix in the primary structure of hIL-10 (amino acids 19-35 and amino acids 86-110) that are oriented antiparallel and that could be of relevance in their interaction with the receptor. The sequences of these peptides are indicated below: (SEQ ID NO: 28) Leu Pro Asn Met Leu Arg Asp Leu Arg Asp Ala Phe Ser

- solubilizing agents such as guanidine hydrochloride, ethanol, methanol, isopropanol, dimethylformamide (DMF), acetone, acetonitrile, ammonia and acetic acid.
- Guanidine hydrochloride proved to be very toxic at all concentrations tested.
- the maximum final concentration, compatible with the assay, of acetic acid, DMSO and DMF was 0.01 or 0.005%, concentrations that do not allow solubilization of peptides In the case of urea, the limit concentration was 125 raM, and 0.2% ammonia (maximum tested).

Urea is relatively toxic (cpm without urea 1,128, with 120 mM urea 109, with 80 raM 308 and with 20 mM 800, but the window is maintained).
- Table 3 summarizes the conditions used to solubilize the peptides. Of the total of 39 indicated peptides, 1 1 (bold) could not be solubilized with any of the conditions indicated, so they could not be tested in the in vitro assay.
- peptides capable of inhibiting the activity of IL-10 to the culture of MC / 9 cells has the effect of inhibiting the proliferation of these cells because IL-10 promotes the proliferation of these.
- the addition of a peptide or some component to the culture (used to improve the solubility of the peptide) that was toxic to MC / 9 cells would also have the effect of inhibiting cell proliferation. For this reason, to ensure that a peptide actually inhibits IL-10, and not proliferation due to cell toxicity, it is necessary to demonstrate that the peptide or other agent that is added to the culture is not toxic to the cells.
