Hereditary diffuse white matter encephalopathy (HDLS) is a rare autosomal dominant hereditary white matter disease, which is clinically mainly manifested by progressive cognitive impairment, Parkinson's disease, epilepsy, personality and behavior changes and the like, and is asymmetric white matter impairment on nuclear magnetic resonance imaging.
At present, no effective HDLS treatment method exists in clinic, and the treatment method is mainly used for symptomatic treatment and mainly comprises general nursing, nutrition support, anti-epilepsy drugs and antibiotics. The method specifically comprises the following steps: the effectiveness of L-dopa (levodopa) or other dopamine therapy for HDLS or HDLS patients with atypical Parkinson's phenotype has not been demonstrated. Antidepressants may be used to treat the symptoms of depression, but there are no long-term effective reports. Antipsychotic drugs are generally not recommended for routine use due to extrapyramidal side effects, but may be used for a short period in HDLS patients with significant psychiatric symptoms. As the condition of HDLS progresses, social problems (unemployment, divorce, financial difficulties, alcoholism) and suicidal tendency are often accompanied. Periodically performing clinical assessment and monitoring changes in HDLS patient behavior and communication, changing care and support systems (wheelchairs or personal assistance) in time; appropriate physical rehabilitation therapy helps to improve the quality of life by reducing muscle contracture, gastrostomy when dysphagia is severe, and the like.
The only causative gene has been identified to date as the Colony Stimulating Factor 1Receptor (CSF1R, Colony Stimulating Factor 1Receptor) gene. CSF1R gene encodes type III tyrosine kinase receptor, belong to platelet-derived growth factor receptor family, it is 972 amino acids (19 amino acid signal peptide, 493 amino acid extracellular region, 25 amino acid transmembrane region, 435 amino acid intracellular tyrosine kinase catalytic region), mainly express mononuclear phagocyte (also called microglia) in the brain, the microglia has important roles in neuronal and brain development; also expressed in osteoclasts, which play an important role in bone mineralization. CSF1R forms a dimer with ligands (CSF1, IL-34) and activates multiple downstream kinase signaling pathways, including phosphatidylinositol 3-kinase (PI3K), extracellular regulatory protein kinase (ERK1/2), and c-Jun amino terminal kinase (JNK), via autophosphorylation.
In 2012, genome-wide association analysis and exon sequencing confirmed that HDLS is an autosomal dominant genetic disease (disease cases show that HDLS can sporadically develop diseases and incomplete exons), CSF1R is a pathogenic gene of HDLS, and influence of CSF1R mutation on a tyrosine kinase domain may be the pathological basis of HDLS. By 1 month of 2018, 71 HDLS pathogenic mutations (56 missense mutations, 8 splice site mutations, 3 frameshift mutations, 2 nonsense mutations, 2 small deletions) were found. Almost all pathogenic mutations occur in the intracellular tyrosine kinase domain, mainly in exons 18 and 19, while mutations in the extracellular domain or increased CSF1R copy number may lead to the development of hematologic tumors or renal cell carcinoma. Whether HDLS pathogenic mutations affect CSF1R autophosphorylation has not been a uniform result. Whether the pathogenic mechanism of HDLS is dominant negative or haploidentical insufficiency cannot be determined.
The pathogenic mechanism of HDLS has been studied for a short time and has not been clearly concluded. With the continuous development and improvement of cell therapy and gene therapy technology, the substitution and treatment of diseased tissues by using genetically engineered cells has become a research hotspot in the medical field and even in the whole life science field. Hematopoietic stem cells can enter the brain and differentiate into microglia have been demonstrated in mice. Currently, there is no effective treatment for HDLS in clinical practice, and new treatments are urgently needed to improve the survival status of HDLS patients. The technical solution provided by the present invention addresses this need.
Gene therapy refers to the introduction of foreign genes into target cells to correct or compensate for diseases caused by gene defects or abnormal expression of genes. The invention aims to modify hematopoietic stem cells in vitro by a gene therapy vector so as to treat hereditary diffuse leukoencephalopathy with axonal spheroidicity (HDLS).
1. Gene therapy vector
In a first aspect the present invention provides a gene therapy vector for the treatment of HDLS comprising:
a) left (5') LTR;
b) psi (Psi) package signal;
c) a retroviral export element;
d) central polypurine tract/central termination sequence;
e) a promoter operably linked to a polynucleotide encoding a colony stimulating factor 1receptor polypeptide;
f) a polynucleotide encoding a colony stimulating factor 1receptor polypeptide;
g) a post-transcriptional regulatory element; and
h) right (3') LTR.
In the present invention, the gene therapy vector includes: a gamma retroviral vector, an adeno-associated virus (AAV) vector, an adenoviral vector, or a herpes viral vector; preferably, the gene therapy vector is a lentiviral vector, which is a broad class of retroviral vectors, preferably a Human Immunodeficiency Virus (HIV).
The Long Terminal Repeat (LTR) is a base pair domain located at the end of the retroviral DNA, which in the case of its native sequence is a direct repeat and contains the U3, R and U5 regions. LTRs typically provide essential functions for retroviral gene expression (e.g., initiation, and polyadenylation of gene transcripts) and viral replication. The LTRs contain numerous regulatory signals including transcriptional control elements, polyadenylation signals, and sequences required for replication and integration of the viral genome. The viral LTR is divided into three regions called U3, R and U5. The U3 region contains enhancer and promoter elements. The U5 region is a sequence between the primer binding site and the R region and contains a polyadenylation sequence. The R (repeat sequence) region is flanked by the U3 and U5 regions. The LTRs are composed of the U3, R, and U5 regions, and occur at the 5 'and 3' ends of the viral genome.
"packaging signal" refers to a sequence located within the retroviral genome required for insertion of viral RNA into the viral capsid or particle. Several retroviral vectors use a minimal packaging signal (also known as a psi [ psi ] sequence) required for encapsidation of the viral genome.
"retroviral export element" refers to a cis-acting post-transcriptional regulatory element that regulates the transport of RNA transcripts from the nucleus to the cytoplasm. Retroviral export elements include, but are not limited to, the Human Immunodeficiency Virus (HIV) Rev Response Element (RRE) and the hepatitis B virus post-transcriptional regulatory element (HPRE).
The gene therapy vector contains cis-acting elements, namely a central polypurine tract (cPPT) and a Central Termination Sequence (CTS), wherein the cPPT/CTS sequence can be the cPPT/CTS of HIV1, and the integration and transduction efficiency of the vector can be improved.
By "operably linked" is meant that the nucleic acid sequences are functionally related to the sequences to which they are operably linked such that they are linked in a manner such that they affect the expression or function of each other. For example, a nucleic acid sequence operably linked to a promoter will have an expression pattern that is affected by the promoter.
Promoters mediate the expression of nucleic acid sequences to which they are linked. Promoters may be constitutive or may be inducible. The promoter may direct expression prevalent in hematopoietic stem cells, or progenitor cells. A promoter operably linked to a polynucleotide encoding a colony stimulating factor 1receptor polypeptide comprises: short elongation factor 1 alpha (EF1 alpha) promoter or a transcriptionally active fragment thereof, a MND promoter or a transcriptionally active fragment thereof in which the myeloproliferative sarcoma virus enhancer negative control region is deleted and the dl587rev primer binding site is substituted (see Challita et al, J Virol., 69(2):748-55 (1995)); suitable promoters may be selected from the following: transmembrane protein 119(TMEM119), integrin subunit α M (CD11B), CD45 (expressed by hematopoietic cells), ionic calcium binding adaptor 1(IBA1), C-X3-C motif chemokine receptor 1(CX3CR1), adhesion G protein-coupled receptor E1(F4/80), CD68 (expressed by macrophages), or CD40 (expressed by T and B cells).
The short elongation factor 1 α (EF1 α) promoter refers to the original EF1 α promoter that lacks the first intron of the human EF1a gene.
The post-transcriptional regulatory element may improve transgene expression by promoting mRNA transcript maturation, and may be woodchuck hepatitis virus post-transcriptional regulatory element (WPRE).
In a preferred embodiment of the present invention, the above gene therapy vector further comprises a nucleotide sequence encoding an expression tag;
preferably, the expression tags are truncated epidermal growth factor receptor (EGFRt), firefly luciferase, Enhanced Green Fluorescent Protein (EGFP), streptavidin-binding peptide tag Strep tag II, or Flag tag, which can be attached to the C-terminus or N-terminus of a protein of interest (e.g., colony stimulating factor 1receptor polypeptide) to measure the expression of the protein of interest in a particular cell in an assay. EGFRt is a truncated form of EGFRt in which domain III and domain IV of a wild-type EGFR are truncated, and this truncated EGFRt does not transmit an intracellular signal and does not transmit other signals into cells. The Enhanced Green Fluorescent Protein (EGFP) is a mutant of the Green Fluorescent Protein (GFP), emits fluorescence intensity which is more than 6 times that of the GFP, and is expressed by escherichia coli, and the non-glycosylated homodimeric protein contains 239 amino acids and has the molecular weight of 26.9 kDa. The streptavidin-binding peptide tag (Strep tag II) consists of 8 amino acid residues, the sequence being Trp-Ser-His-Pro-Gln-Phe-Glu-Lys (W-S-H-P-Q-F-E-K). The Flag tag (Flag tag) consists of 8 amino acid residues, and the sequence is Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys (D-Y-K-D-D-D-D-K)
In a preferred embodiment of the invention, the promoter of the left (5') LTR is replaced by a heterologous promoter selected from the group consisting of: cytomegalovirus (CMV) promoter, Rous Sarcoma Virus (RSV) promoter, or simian virus 40(SV40) promoter, i.e., by replacing the U3 region of the (5') LTR with a heterologous promoter to provide additional safety enhancements to drive transcription of the viral genome during viral particle production. This substitution reduces the likelihood of recombination to generate a replication competent virus because the complete U3 sequence is not present in the virus production system.
The safety of gene therapy vectors is crucial for any possible gene therapy. The gene therapy vectors of the invention include one or more modifications, including but not limited to modifications to one or more LTRs, to render the vector replication deficient. For example, the gene therapy vector includes a modified 3'LTR, wherein the modification includes deletion of viral promoters and enhancers in the U3 region of the 3' LTR to prevent viral transcription beyond the first round of viral replication. This is because the right (3') LTR U3 region is used as a template for the left (5') LTR U3 region during viral replication, and thus, without the U3 enhancer-promoter, the viral transcription cannot proceed.
The self-inactivating (SIN) LTR is a fragment in which the enhancer and promoter sequences of the U3 region of the viral 3' LTR are deleted from the proviral vector, so that the HIV-1 enhancer and promoter sequences are lost from the vector and RNA cannot be transcribed even if all viral proteins are present.
In a preferred embodiment of the invention, wherein the polynucleotide sequence encoding a colony stimulating factor 1receptor (CSF1R) polypeptide is as set forth in SEQ ID NO: 3, namely the original sequence of the CSF1R polypeptide;
preferably, the polynucleotide encoding the colony stimulating factor 1receptor polypeptide is a codon optimised expression sequence as set forth in SEQ ID NO: 4 to enhance its expression in a host cell. The main process of codon optimization: preferentially selecting codons preferred by the expression host cells according to the codon preference, and eliminating rare codons; the GC content of the whole encoding gene is adjusted to a suitable range by the principle that the codon having the highest AT content is selected preferentially among a plurality of synonymous codons corresponding to the same amino acid. In addition, the codon optimization process also needs to consider: stability of secondary structure of mRNA, elimination of tandem rare codons, avoidance of codon duplication, adjustment of ribosome binding sites, attention to the environment of the initiation termination codon, and the like. In a preferred embodiment of the invention, wherein the amino acid sequence of the colony stimulating factor 1receptor polypeptide is as set forth in SEQ ID NO: 5, respectively.
