  • Publication number: 20080014246
    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).

  • Publication number: 20070196338
    Abstract: The present invention is based on the finding that parvovirus (including AAV) capsids can be engineered to incorporate small, selective regions from other parvoviruses that confer desirable properties. In some embodiments, a substitution of a single amino acid that is unique to the AAV6 capsid (Lys-531) among other AAVs that have been characterized to date can confer one or more desirable properties to other AAVs.

  • Publication number: 20070110724
    Abstract: The present invention provides duplexed parvovirus vector genomes that are capable under appropriate conditions of forming a double-stranded molecule by intrastrand base-pairing. Also provided are duplexed parvovirus particles comprising the vector genome. Further disclosed are templates and methods for producing the duplexed vector genomes and duplexed parvovirus particles of the invention. Methods of administering these reagents to a cell or subject are also described. Preferably, the parvovirus capsid is an AAV capsid. It is further preferred that the vector genome comprises AAV terminal repeat sequences.

  • Publication number: 20060188483
    Abstract: 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.

  • Publication number: 20060046295
    Abstract: A method for the production of adeno-associated virus stocks and recombinant adeno-associated virus stocks that are substantially free of contaminating helper virus is described. The method utilizes transfection with helper virus vectors to replace the infection with helper virus used in the conventional method.

  • Publication number: 20050287662
    Abstract: The present invention relates to a method for producing helper-free stocks of recombinant adeno-associated virus (rAAV) which can be used to efficiently and stably transduce foreign genes into host cells or organisms. The method comprises the cotransfection of eukaryotic cells with rAAV and with helper AAV DNA in the presence of helper virus (e.g. adenovirus or herpesvirus) such that the helper AAV DNA is not associated with virion formation. The crux of the invention lies in the inability of the helper AAV DNA to recombine with rAAV vector, thereby preventing the generation of wild-type virus. In a specific embodiment of the invention, the vector comprises a recombinant AAV genome containing only the terminal regions of the AAV chromosome bracketing a non-viral gene, and the helper AAV DNA comprises a recombinant AAV genome containing that part of the AAV genome which is not present in the vector, and in which the AAV terminal regions are replaced by adenovirus sequences.
