This invention provides RNA, oligoribonucleotide, and polyribonucleotide molecules comprising pseudouridine or a modified nucleoside, gene therapy vectors comprising same, methods of synthesizing same, and methods for gene replacement, gene therapy, gene transcription silencing, and the delivery of therapeutic proteins to tissue in vivo, comprising the molecules. The present invention also provides methods of reducing the immunogenicity of RNA, oligoribonucleotide, and polyribonucleotide molecules.

The present disclosure provides compositions and methods for making and using engineered killer phagocytic cells for immunotherapy in cancer or infection by expressing a chimeric antigen receptor having an enhanced phagocytic activity, the chimeric receptor is encoded by a recombinant nucleic acid.

Described herein are compositions and methods for tissue-targeted expression of therapeutic genes, using AAV expression vectors that reduce the risk of toxicity associated with AAV gene therapy in the CNS by de-targeting the vulnerable neurons cells including the DRG cells on gene expression, and de-targeting the liver, a major suspect for over-expression in the periphery.

Disclosed are a composition and method of treating or preventing cardiomyopathy in a human subject. In one embodiment, a method comprises delivering a gene therapy drug to cardiac tissue of the human subject. The gene therapy drug comprises: a first vector comprising a first portion of a polynucleotide sequence encoding for a therapeutic protein; and a second vector comprising a second portion of the polynucleotide sequence encoding for the therapeutic protein.

Disclosed are methods for treating neurological disorders such as Parkinson's disease (PD) using glutamic acid decarboxylase (GAD) and identifying PD patients that will be most receptive to the method of treating PD. In one aspect, the disclosure provides a method of treating PD in a subject in need thereof, the method comprising: (a) identifying a subject having less than about 10 hours, and preferably less than about 8 hours, of on-time per day; and (b) administering to the subject a composition comprising a therapeutically effective amount of one or more vectors to the subthalamic nucleus of the patient, wherein each vector comprises a nucleic acid sequence encoding glutamic acid decarboxylase (GAD) and wherein the subject's on-time is increased.

The present disclosure encompasses engineered meganucleases that bind and cleave recognition sequences within a dystrophin gene. The present disclosure also encompasses methods of using such engineered meganucleases to make genetically modified cells. Further, the disclosure encompasses pharmaceutical compositions comprising engineered meganuclease proteins, or polynucleotides encoding engineered meganucleases of the disclosure, and the use of such compositions for the modification of a dystrophin gene in a subject, or for treatment of Duchenne Muscular Dystrophy.

The present disclosure provides compositions and methods for cell transplantation therapy based on forced expression of an exogenous HLA-F protein in donor cells to be transplanted into a subject. In some embodiments, the donor cells express an exogenous chimeric HLA-F protein comprising an extracellular region comprising an HLA-F alpha 1 domain, an HLA alpha 2 domain, an HLA-F alpha 3 domain, a linker and a β2m protein.

The present disclosure provides compositions and methods of restoring or enhancing visual function in an individual by administering to the individual a pharmaceutical composition comprising a recombinant adeno-associated viral (rAAV) vector having a polynucleotide sequence that encodes a medium wavelength cone opsin (MW-opsin). The MW-opsin is expressed in a retinal cell in the individual, thereby restoring or enhancing visual function.

Disclosed herein include adeno-associated virus (AAV) acoustic targeting peptides. An AAV comprising the AAV acoustic targeting peptide can exhibit increased transduction at site(s) of focused ultrasound blood-brain barrier opening (FUS-BBBO), increased neuronal tropism, and diminished transduction of peripheral organs. Disclosed herein include recombinant adeno-associated virus (rAAV) comprising an AAV acoustic targeting peptide disclosed herein. Also provided herein include methods of delivering an agent to one or more target brain region(s) of a subject.

Aspects of the disclosure relate to compositions and methods for expressing anti-Vascular endothelial cell growth factor (VEGF) agent in a cell or subject. In some embodiments, the disclosure provides rAAVs comprising a capsid protein (e.g., AAV2 variants, AAV2/3 hybrid variants, AAV8 variants, etc.), and a transgene encoding an anti-VEGF agent (e.g., KH902) and one or more regulatory sequences. In some embodiments, compositions described herein are useful for treating subjects having diseases associated with angiogenesis or aberrant VEGF activity/signaling.
