The present invention relates to a Crumbs homologue (CRB) therapeutic for use as a medicament or in a method of treatment or prophylaxis, for example in the treatment or prophylaxis of a retinal disorder due to mutations in the Crumbs homologue-1 (CRB1) gene, such as Leber's congenital amaurosis 8 (LCA8) or retinitis pigmentosa 12 (RP12). In particular, the present invention relates to a recombinant viral vector comprising CRB2 or modified non-toxic forms of either CRB1 or CRB3 that resemble CRB2.

This document relates to methods and materials for increasing viral vector infectivity. For example, methods and materials for using spliceosome inhibitors (e.g., U2 snRNP spliceosome inhibitors such as meayamycin B or pladienolide derivative E7107) to increase viral vector (e.g., adeno-associated virus-based vector) infectivity are provided.

The present invention relates to nucleic acid regulatory elements that are able to enhance muscle-specific expression of genes, in particular expression in cardiac muscle and/or skeletal muscle, methods employing these regulatory elements and uses of these elements. Expression cassettes and vectors containing these nucleic acid regulatory elements are also disclosed. The present invention is particularly useful for applications using gene therapy, more particularly muscle-directed gene therapy, and for vaccination purposes.

This disclosure provides gene therapy vectors comprising a polynucleotide encoding one or more isoforms of lysosome-associated membrane protein 2 (LAMP-2), and methods of using such gene therapy vectors for the treatment of Danon disease and other autophagy disorders.

In certain aspects, the present invention provides methods for inducing a stable gene modification of a target nucleic acid via homologous recombination in a primary cell, such as a primary blood cell and/or a primary mesenchymal cell. In certain other aspects, the present invention provides methods for enriching a population of genetically modified primary cells having targeted integration at a target nucleic acid. The methods of the present invention rely on the introduction of a DNA nuclease such as a Cas polypeptide and a homologous donor adeno-associated viral (AAV) vector into the primary cell to mediate targeted integration of the target nucleic acid. Also provided herein are methods for preventing or treating a disease in a subject in need thereof by administering to the subject any of the genetically modified primary cells or pharmaceutical compositions described herein to prevent the disease or ameliorate one or more symptoms of the disease.

Disclosed herein are Htt repressors and methods and compositions for use of these Htt repressors.

In particular, the present invention relates to a recombinant viral vector comprising CRB2 or modified non-toxic forms of either CRB1 or CRB3 that resemble CRB2.

They are provided gene constructs comprising a nucleotide sequence encoding the Insulin-like growth factor 1 (IGF-1) of a mammal; and target sequences of a microRNA of a tissue where the expression of IGF-1 is wanted to be prevented, wherein the sequences (a) and (b) are operationally linked to a promoter of ubiquitous expression. Also provided are expression vectors comprising the gene construct and pharmaceutical compositions comprising them. They are useful in the treatment and/or prevention of diabetes mellitus in mammals, wherein a dysfunction and/or a loss of the beta-cells of the islets of Langerhans is present.
