This disclosure provides methods and compositions for treating disorders or injuries that affect motor function and control in a subject. In one aspect, the invention a transgene product is delivered to a subject's spinal cord by administering a recombinant viral vector containing the transgene to the spinal cord. The viral vector delivers the transgene which expresses the encoded recombinant viral gene product. The viral gene product comprises HIF1-alpha. Also provided are compositions for delivery of a transgene product to a subject's spinal cord.

A method of preparing a chimeric virus comprising bocavirus capsid protein (VP) and a recombinant adeno-associated (AAV) viral genome, and isolated mutant bocavirus genomes, are provided.

Provided herein are methods of selective screening. In addition, various targeting proteins and sequences, as well as methods of their use, are also provided.

A method of preparing a chimeric virus comprising bocavirus capsid protein (VP) and a recombinant adeno-associated (AAV) viral genome, and isolated mutant bocavirus genomes, are provided.

Novel adeno-associated virus (AAV) vectors in nucleotide and amino acid forms and uses thereof are provided. The isolates show specific tropism for certain target tissues, such as blood stem cells, liver, heart and joint tissue, and may be used to transduce stem cells for introduction of genes of interest into the target tissues. Certain of the vectors are able to cross tightly controlled biological junctions, such as the blood-brain barrier, which open up additional novel uses and target organs for the vectors, providing for additional methods of gene therapy and drug delivery.

The present invention provides AAV capsid proteins comprising a modification in the amino acid sequence and virus vectors comprising the modified AAV capsid protein. The invention also provides methods of administering the virus vectors and virus capsids of the invention to a cell or to a subject in vivo.

The invention provides an isolated chimeric virus comprising bocavirus capsid protein and a recombinant adeno-associated viral (AAV) genome, an isolated rBoV comprising human bocavirus capsid protein and a recombinant BoV genome, and uses therefor. For example, the chimeric virus may be employed to deliver transgenes, such as those encoding therapeutic or prophylactic gene products, to mammalian cells.

The present invention provides AAV capsid proteins comprising a modification in the amino acid sequence and virus vectors comprising the modified AAV capsid protein. The invention also provides methods of administering the virus vectors and virus capsids of the invention to a cell or to a subject in vivo.

Disclosed are tyrosine-modified rAAV vectors, as well as infectious virions, compositions, and pharmaceutical formulations that comprise them. Also disclosed are methods of preparing and methods for using the disclosed tyrosine-phosphorylated capsid protein mutant rAAV vectors in a variety of diagnostic and therapeutic applications including in vivo and ex vivo gene therapy, and large-scale production of rAAV vectors.

Compositions and methods for producing modified AAV Cap genes and combinatorial libraries of chimeric AAV vectors and virions in an AAV serotype 3 background. Selecting for modified AAV3 virions displaying cell- or tissue-specific tropisms differing from WT AAV3. Using the synthetic combinatorial AAV3 capsid libraries for introducing into a selected target host cells one or more nucleic acid molecules useful in diagnostic and/or therapeutic gene-therapy regimens.
