Abstract: The present invention relates to an expression system for systemic administration comprising a sequence encoding a protein, said expression system allowing: the expression at a therapeutically acceptable level of the protein in the target tissues including skeletal muscles; and the expression at toxically acceptable level of the protein in tissues other than the target tissues, especially in the heart.

Abstract: The present invention relates to compositions and methods, in particular to methods based on systemic injection of rAAV, for delivering genes to cells of the central nervous system in mammals, such as brain neurons or glial cells, and in particular to motor neurons or glial cells of the spinal cord The invention also relates to methods of treating motor neuron disorders in mammals by expression of therapeutic genes. The invention stems from the unexpected discovery that peripheral injection of AAV vectors leads to a bypass of the blood brain barrier and a massive infection of motor neurons. The invention may be used in any mammal, including human subjects.

Abstract: The present invention concerns synthetic polynucleotides encoding a human fukutin-related protein (FKRP) wherein the synthetic polynucleotides contain at least a mutation avoiding supplementary transcript(s) generated from frameshift start codon(s). The synthetic polynucleotides are useful, especially for treating a pathology linked to a FKRP deficiency or induced by a defect in ?-dystroglycan (?-DG) glycosylation, such as LGMD2I.

Abstract: The present invention provides compositions and methods for treating a myopathy. In certain embodiments, the invention provides compositions and methods for treating, improving muscle function, and prolonging survival in a subject with X-linked myotubular myopathy (XLMTM). The present invention provides a method comprising systemic administration of a composition that induces the increased expression of myotubularin in the muscle of a subject. The invention provides sustained regional and global increases in muscle function.

Abstract: The present invention relates to vectors and compositions for the treatment of glycogen storage disease III.

Abstract: The present invention concerns the use of antisense oligonucleotides (AON) capable of inhibiting expression of dynamin 2, advantageously human dynamin 2, for use in the treatment of Charcot-Marie-Tooth disease (CMT) and centronuclear myopathies (CNM).

Abstract: The present invention relates to a method for treating a Leber congenital amaurosis in a patient harbouring the mutation c.2991+1655 A>G in the CEP290 gene, comprising the step of administering to said patient at least one antisense oligonucleotide complementary to nucleic acid sequence that is necessary for preventing splicing of the cryptic exon inserted into the mutant c. 2991+1655 A>G CEP290 mRNA.

Abstract: Adeno-associated virus (AAV) is a defective mono-stranded DNA virus, endemic in human population (35-80%). Recurrent clonal AAV2 insertions are associated with the pathogenesis of rare human hepatocellular carcinoma (HCC) developed on normal liver. The aimed of the inventors was to characterize the natural history of AAV infection in the liver. Viral DNA was thus quantified in tumor and non-tumor liver tissues of 1461 patients. Presence of episomal form and viral mRNA expression were analyzed using a DNAse/TaqMan based assay and quantitative RT-PCR. In silico analyses using viral capture data explored viral variants and new clonal insertions. AAV DNA was detected in 21% of the patients equally distributed in 2 major viral subtypes: one similar to AAV2, the other hybrid between AAV2 and AAV13 sequences. Thus the inventors provided an integrated analysis of the wild type AAV infection in the liver with the identification of viral genotypes, molecular forms, helper virus relationship and viral integrations.

Abstract: The present invention relates to compositions and methods for the treatment of myotonic dystrophy.

Abstract: An RNA interference (RNAi) strategy is provided based on use of artificial microRNA (amiR) to reduce NKCC1 expression. In particular, a method is provided that achieves neuron-specific expression of specific amiR against NKCC1 by using a human Synapsin promoter to drive transgene expression.

Abstract: The present invention relates to variants of acid-alpha glucosidase and uses thereof. Said variants are sequence-optimized and/or are linked to a heterogenous signal peptide.

Abstract: The invention relates to a recombinant adeno-associated virus (AAV) capsid protein, which is a peptide-modified hybrid between AAV serotype 9 (AAV9) and AAV serotype 74 (AAVrh74) capsid proteins comprising at least one copy of a peptide comprising the RGD motif, wherein said recombinant peptide-modified hybrid AAV capsid protein has a further reduced liver tropism and an increased muscle transduction compared to the recombinant hybrid AAV capsid protein not having said peptide. The invention relates also to the derived peptide-modified hybrid AAV serotype vector particles packaging a gene of interest and their use in gene therapy, in particular for treating neuromuscular genetic diseases, in particular muscular genetic diseases.
