The invention provides adeno-associated virus (AAV) Factor VIII (FVIII)-encoding/expressing vectors and virus, including AAV FVIII vectors with high expression activity and AAV FVIII vectors that express full-length or truncated functional FVIII protein. The invention also relates to methods of making the herein described AAV FVIII vectors, recombinant AAV FVIII virus particles comprising or expressing such vectors, associated pharmaceutical formulations comprising the same and therapeutic uses thereof.

This invention relates to modified parvovirus inverted terminal repeats (ITRs) that do not functionally interact with wild-type large Rep proteins, synthetic Rep proteins that functionally interact with the modified ITRs, and methods of using the same for delivery of nucleic acids to a cell or a subject. The modifications provide a novel Rep-ITR interaction that limits vector mobilization, increasing the safety of viral vectors.

Provided herein are CD70 targeting chimeric antigen receptors and engineered immune cells (e.g., T cells) comprising such CAR. Method of treating a cancer expressing CD70 using such engineered immune cells are also provided. In some embodiments, the method of treating cancer further comprising using an agent that enhances CD70 expression in the cancer (e.g., azacitidine) in combination with the engineered immune cells comprising the CD70-targeting CAR.

Modified G6PC (glucose-6-phosphatase, catalytic subunit) nucleic acids and glucose-6-phosphatase-α (G6Pase-α) enzymes with increased phosphohydrolase activity are described. Also described are vectors, such as adeno-associated virus (AAV) vectors, and recombinant AAV expressing modified G6Pase-α. The disclosed AAV vectors and rAAV can be used for gene therapy applications in the treatment of glycogen storage disease, particularly glycogen storage disease type Ia (GSD-Ia), and complications thereof.

Angelman Syndrome (AS) is a genetic disorder occurring in approximately one in every 15,000 births. It is characterized by severe mental retardation, seizures, difficulty speaking and ataxia. The gene responsible for AS was discovered to be UBE3A and encodes for E6-AP, an ubiquitin ligase. A unique feature of this gene is that it undergoes maternal imprinting in a neuron-specific manner. In the majority of AS cases, there is a mutation or deletion in the maternally inherited UBE3A gene, although other cases are the result of uniparental disomy or mismethylation of the maternal gene. While most human disorders characterized by severe mental retardation involve abnormalities in brain structure, no gross anatomical changes are associated with AS. We have generated a Ube3a protein with additional sequences that should allow the secretion from cells and uptake by neighboring neuronal cells. This would confer a functional E6-AP protein into the neurons and rescue disease pathology.

The present invention relates to pharmaceutical compositions for preventing or treating pulmonary metastasis of cancer. More specifically, the present invention relates to compositions that enhance anti-cancer immunity of the lung rather than induce death of advanced cancer, thus being effective in inhibiting, preventing or treating pulmonary metastasis of cancer.

Disclosed herein are compositions and methods of treating and/or correcting ocular disease in a subject, such as a mammal (e.g., human) eye using an Adeno-associated virus (AAV) system. The AAV system employs a nucleic acid encoding a CRISPR-Cas9 system for targeted gene disruption or correction.

The present disclosure is in the field of diagnostics and therapeutics for Alzheimer's Disease.

Compositions and methods useful for altering a P347 mutation in a RHO gene.

Provided herein are variant adeno-associated virus (AAV) capsid proteins having one or more modifications in amino acid sequence relative to a parental AAV capsid protein, which, when present in an AAV virion, confer increased infectivity of one or more types of muscle cells as compared to the infectivity of the muscle cells by an AAV virion comprising the unmodified parental AAV capsid protein. Also provided are recombinant AAV virions and pharmaceutical compositions thereof comprising a variant AAV capsid protein as described herein, methods of making these rAAV capsid proteins and virions, and methods for using these rAAV capsid proteins and virions in research and in clinical practice, for example in, e.g., the delivery of nucleic acid sequences to one or more muscle cells for the treatment of muscle disorders and diseases.
