Abstract: Provided herein are novel AAV capsids and recombinant AAV vectors comprising the same. In certain embodiment, vectors comprising a novel AAV capsid show improved transduction of cardiac tissue and/or reduced targeting of liver tissue compared to a prior art AAV capsid.

Abstract: The present disclosure provides lipolytic enzyme variants having one or more modifications as compared to a parent lipolytic enzyme. Specifically, the present disclosure provides one or more lipolytic enzyme variants that has at least one improved performance when compared to one or more reference lipolytic enzymes. In addition, the present disclosure provides compositions comprising a lipolytic enzyme variant of the disclosure. The present disclosure also provides methods of cleaning using compositions comprising a lipolytic enzyme variant of the disclosure.

Abstract: Provided herein are compositions including brain-capillary binding and/or blood-brain barrier crossing (BBB) tissue-targeting peptides linked thereto or inserted in a targeting protein of a recombinant vector having at least one exogenous peptide comprising an amino acid sequence of Y-G/A/R/K-Y/H-GNPA-T/R/H-RYFD-V/K. Compositions providing such conjugates, targeting peptides, or recombinant vectors having a mutant capsid or envelope protein are provided as are uses thereof.

Abstract: Provided herein are compositions including targeting peptides linked thereto or inserted in a targeting protein of a recombinant vector having at least one exogenous peptide comprising an amino acid sequence of N-x-(T/I/V/A)-(K/R) (SEQ ID NO: 47). Compositions providing such conjugates, targeting peptides, or recombinant vectors having a mutant capsid or envelope protein are provided as are uses thereof.

Abstract: A mutant soluble human Ace2 (hAce2) protein useful in preventing infection with betacoronaviruses, including SARS-CoV2 is provided, as are compositions useful in treating disease associated with betacoronavirus, including, e.g, COVID-19. Also provided are compositions containing same formulated for intranasal and/or intrapulmonary delivery, methods of making same and assays. The use of the rAAV compositions for preventing symptoms of COVID-19 infection in humans is provided.

Abstract: A recombinant adeno-associated virus (rAAV) vector comprising an AAV capsid having a heterogeneous population of vp1 proteins, a heterogeneous population of vp2 protein and a heterogeneous population of vp3 proteins. The capsid contains modified amino acids as compared to the encoded VP1 amino acid sequence, the capsid containing highly deamidated asparagine residues at asparagine-glycine pair, and further comprising multiple other, less deamidated asparagine and optionally glutamine residues.

Abstract: A recombinant adeno-associated virus (rAAV) vector comprising an AAV capsid having a heterogeneous population of vp1 proteins, a heterogeneous population of vp2 protein and a heterogeneous population of vp3 proteins. The capsid contains modified amino acids as compared to the encoded VP1 amino acid sequence, the capsid containing highly deamidated asparagine residues at asparagine-glycine pair, and further comprising multiple other, less deamidated asparagine and optionally glutamine residues. Methods of reducing deamidation in the AAV capsid of a rAAV are provided.
