  • Patent number: 8679837
    Abstract: Production of clinical grade gene therapy vectors for human trials remains a major hurdle in advancing cures for a number of otherwise incurable diseases. Disclosed herein are systems based on a stably trans formed insect cell lines harboring helper genes required for vector production. Specifically exemplified are system embodiments that take advantage of DNA regulatory elements from two unrelated viruses—AcMNPV and AA V2. System embodiments utilize rep and/or cap genes either stably transfected in cell lines or which are introduced into cells as an expression cassette in a vector. Rep and cap genes that are designed to remain silent until the cell is infected with a viral vector. Infection with viral initiates rescue/amplification of integrated AAV helper genes resulting in dramatic induction of the expression and assembly of rAAV. The arrangement of this specific embodiment provides high levels of Rep and Cap proteins in every cell thus improving rAAV yields by 10-fold.

  • Patent number: 7220577
    Abstract: Libraries of modified AAV cap genes are generated by synthesizing modified cap genes using degenerate oligonucleotides. Combinatorial libraries of virions composed of modified (e.g., chimeric), replication-competent AAV vectors and modified Cap proteins are also produced. Helper vectors are described that encode AAV Rep protein, modified Cap proteins, and Ad proteins. The helper vectors are used to produce stocks of virions composed of modified (e.g., chimeric) capsids and rAAV vectors.

  • Publication number: 20060239972
    Abstract: Adiponectin cDNA was cloned into AAV serotypes 1, 2, and 5-based expression vectors. Virions containing these vectors were administered to the livers of rat subjects via portal vein injection. A single injection of 6×1011 virions of the vector caused a sustained and statistically significant reduction in body weight of the treated animals compared to the control animals. This occurred in the absence of side effects. Compared to control animals, the subject rats also exhibited reduced adipose tissue mass, reduced appetite, improved insulin sensitivity, and improved glucose tolerance.
