Abstract: 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.

Abstract: The present invention provides AAV capsid proteins (VP1, VP2 and/or VP3) comprising a modification in the amino acid sequence in the three-fold axis loop 4 and virus capsids and virus vectors comprising the modified AAV capsid protein. In particular embodiments, the modification comprises a substitution of one or more amino acids at amino acid positions 585 to 590 (inclusive) of the native AAV2 capsid protein sequence or the corresponding positions of other AAV capsid proteins. 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.

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.

Abstract: This invention relates to synthetic adeno-associated virus (AAV) inverted terminal repeats (ITRs) that exhibit altered activities compared to a naturally occurring AAV ITR and methods of using the same for delivery of nucleic acids to a cell or a subject. The synthetic ITRs provide a larger packaging capacity and the ability to manipulate activities such as transduction efficiency, cellular response to transduction, and transcription.

Abstract: This invention relates to a HEK293 cell line that grows under animal component-free suspension conditions. The cell line is ideal for rapid and scalable production of adeno-associated virus (AAV) and supports production of all serotypes and chimera of AAV.

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.

The invention delivers therapeutic viral vectors via rAAV affixed to support matrixes (i.e., sutures, surgically implantable materials, grafts, and the like).

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.
