Packaging of human chromosome 19-specific adeno-associated virus (AAV) integration sites in AAV virions during AAV wild-type and recombinant AAV vector production.
Adeno-associated virus type 2 (AAV-2) establishes latency by site-specific integration into a unique locus on human chromosome 19, called AAVS1. During the development of a sensitive real-time PCR assay for site-specific integration, AAV-AAVS1 junctions were reproducibly detected in highly purified AAV wild-type and recombinant AAV vector stocks. A series of controls documented that the junctio...
متن کاملSerotype-independent method of recombinant adeno-associated virus (AAV) vector production and purification.
A variety of gene transfer strategies have been developed to treat inherited, degenerative, and acquired diseases. Among the different vector systems developed so far, recombinant adeno-associated viral (AAV) vectors have shown notable benefits, including prolonged gene expression, transduction of both dividing and nondividing cells, and a lack of pathogenicity caused by wild-type infections. T...
متن کاملInfectious clones and vectors derived from adeno-associated virus (AAV) serotypes other than AAV type 2.
Adeno-associated viruses (AAVs) are single-stranded dependent parvoviruses being developed as transducing vectors. Although at least five serotypes exist (AAV types 1 to 5 [AAV1 to -5]), only AAV2, AAV3, and AAV4 have been sequenced, and the vectors in use were almost all derived from AAV2. Here we report the cloning and sequencing of a second AAV3 genome and a new AAV serotype designated AAV6 ...
متن کاملIdentification and elimination of replication-competent adeno-associated virus (AAV) that can arise by nonhomologous recombination during AAV vector production.
Adeno-associated virus (AAV) vector preparations are often contaminated with variable amounts of replication-competent AAV (rcAAV), which may influence the behavior of these vectors both in cultured cells and in animals. A packaging plasmid/vector plasmid system containing no significant homology and lacking the wild-type AAV p5 promoter was constructed to eliminate the production of wild-type ...
متن کاملAdipose tissue insulin receptor knockdown via a new primate-derived hybrid recombinant AAV serotype
Adipose tissue plays an essential role in metabolic homeostasis, and holds promise as an alternative depot organ in gene therapy. However, efficient methods of gene transfer into adipose tissue in vivo have yet to be established. Here we assessed the transduction efficiency to fat depots by a family of novel engineered hybrid capsid serotypes (Rec1~4) recombinant AAV vectors in comparison with ...
