The present invention provides genetically-engineered parvovirus capsids and viruses designed to introduce a heterologous gene into a target cell. The parvoviruses of the invention provide a repertoire of vectors with altered antigenic properties, packaging capabilities, and/or cellular tropisms as compared with current AAV vectors.

International Classification:
A61K 48/00 A61F 2/00
US Classification:
424 932, 424423
Abstract:
The invention uses recombinant parvoviruses, and particularly recombinant adeno-associated virus (rAAV) to deliver genes and DNA sequences for gene therapy following manipulation of the therapeutic virus for packaging and transport. The invention delivers therapeutic viral vectors via rAAV affixed to support matrixes (i. e. , sutures, surgically implantable materials, grafts, and the like).

International Classification:
C12N 7/01
US Classification:
4352351, 4353201, 536 245
Abstract:
The present invention is based, in part, on the discovery that parvovirus (including AAV) capsids can be engineered to incorporate small, selective regions from other parvoviruses that confer desirable properties. The inventors have discovered that in some cases as little as a single amino acid insertion or substitution from a first parvovirus (e. g. , an AAV) into the capsid structure of another parvovirus (e. g. , an AAV) to create a chimeric parvovirus is sufficient to confer one or more of the desirable properties of the first parvovirus to the resulting chimeric parvovirus and/or to confer a property that is not exhibited by the first parvovirus or is present to a lesser extent.

US Classification:
514 44, 536 231, 435325
Abstract:
The invention provides nucleic acid segments, compositions and methods for the treatment of heart failure, vascular dysfunction, endothelial dysfunction, diabetes, [Ca]i regulation and NO synthase dysfunction. Adeno-associated and adenovirus are used as gene delivery vectors for the nucleic acid segments to product long term over-expression of S100A1, a small calcium sensing protein associated with the disclosed ailments and dysfunctions.

"It's very icy, especially below Crater Rock," said Reach and Treat paramedic Joseph Rabinowitz, one of the rescuers. "This is the second fall we have responded to this weekend -- fortunately, the first climber was uninjured. Climbers should exercise extreme caution while descending."
