The present invention provides an isolated nucleic acid molecule comprising, or consisting of, the nucleic acid sequence of SEQ ID NO:1 or a nucleic acid sequence of at least 1000 bp having at least 80% identity to said sequence of SEQ ID NO:1, wherein said isolated nucleic acid molecule specifically leads to the expression in cells of the retinal pigment epithelium of a gene when operatively linked to a nucleic acid sequence coding for said gene.

Compositions and methods are described for the delivery of a fully human post-translationally modified (HuPTM) monoclonal antibody (“mAb”) or the antigen-binding fragment of a mAb against human vascular endothelial growth factor (“hVEGF”)—such as, e.g., a fully human-glycosylated (HuGly) anti-hVEGF antigen-binding fragment—to the retina/vitreal humour in the eye(s) of human subjects diagnosed with ocular diseases caused by increased neovascularization, for example, neovascular age-related macular degeneration (“nAMD”), also known as “wet” age-related macular degeneration (“WAMD”), age-related macular degeneration (“AMD”), and diabetic retinopathy.

Provided herein are compositions that include at least two different nucleic acid vectors that, when introduced into a primate cell, the at least two different vectors undergo con catamerization or homologous recombination with each other, thereby forming a recombined nucleic acid that encodes a full-length target protein (e.g., a supporting cell target protein or a hair cell target protein). Also provided are compositions that include a single AAV vector that, when introduced into a primate cell, a nucleic acid encoding a full-length target protein (e.g., a supporting cell target protein or a hair cell target protein) is generated at the locus of the supporting cell target gene, and the primate expresses the target protein (e.g., a supporting cell target protein or a hair cell target protein).

Compositions and methods are described for the delivery of a fully human-glycosylated (HuGly) α-L-iduronidase (IDUA) to the cerebrospinal fluid of the central nervous system (CNS) of a human subject diagnosed with mucopolysaccharidosis I (MPS I).

This present disclosure provides adeno-associated viral vectors, recombinant adeno-associated vims (rAAV), and methods of their use in gene therapy for treating CDKL5 deficiency disorder (CDD). Also provided are pharmaceutical compositions comprising an rAAV of the invention and a pharmaceutically acceptable carrier or excipient. These pharmaceutical compositions may be useful in gene therapy for the treatment of CDD caused by mutations in CDKL.

Aspects of the disclosure relate to a recombinant adeno-virus encoding an anti-Vascular endothelial cell growth factor (VEGF) agent in a cell or subject (e.g., rAAV2.7m8-KH902). In some embodiments, compositions described herein are useful for treating subjects having diseases associated with angiogenesis or aberrant VEGF activity/signaling.

Methods are disclosed for polarizing macrophages to become M2 macrophages. Methods also are disclosed for treating type 1 diabetes in a subject. These methods include administering to the subject a vector comprising a macrophage specific promoter operably linked to a nucleic acid molecule encoding TNF-alpha-induced protein 8-like 2 (TIPE2) protein. In some embodiments, the vector is administered locally to a pancreas of the subject. In further embodiments, compositions are disclosed including a) a vector comprising a macrophage specific promoter operably linked to a nucleic acid molecule encoding TNF-alpha-induced protein 8-like 2 (TIPE2) protein; b) a buffer; and c) a contrast dye for endoscopic retrograde cholangiopancreatography.

The present invention relates to compositions comprising RNA, preferably messenger RNA (mRNA), more preferably self-amplifying RNA (saRNA), and polymers, in particular cationic polymers, such as polyethylenimine (PEI), poly-L-Lysin (PEL), polyvinylamine (PVA) or polyallylamine (PAA), where individual RNA molecules are present in solution. In the formulations, the RNA is preferentially present in the form of monomers, dimers, timers or oligomers, but not as aggregates comprising a large number of RNA molecules per aggregate, in particular large polyplex nanoparticles. The formulations display improved transfection efficacy and they can be used for delivery of RNA to a subject, where they have an improved dose response relationship in comparison to formulations where large aggregates in the form of polyplex nanoparticles are present.

Compositions and methods for treating neurofibromatic disorders are provided herein, such as expressing Merlin protein or a functional fragment thereof from a viral vector.

The invention provides nucleic acids and nucleic acid expression vectors containing optimized mGluR6 promoters for expression of transgenes in the retina. The compositions and methods of the invention are useful for expression of gene products to preserve, improve, or restore phototransduction or vision.
