Adeno-associated virus (AAV) vectors in cancer gene therapy.
Gene delivery vectors based on adeno-associated virus (AAV) have been utilized in a large number of gene therapy clinical trials, which have demonstrated their strong safety profile and increasingly their therapeutic efficacy for treating monogenic diseases. For cancer applications, AAV vectors have been harnessed for delivery of an extensive repertoire of transgenes to preclinical models and, ...
متن کاملPre-Clinical Assessment of Immune Responses to Adeno-Associated Virus (AAV) Vectors
Transitioning to human trials from pre-clinical models resulted in the emergence of inhibitory AAV vector immune responses which has become a hurdle for sustained correction. Early animal studies did not predict the full range of host immunity to the AAV vector in human studies. While pre-existing antibody titers against AAV vectors has been a lingering concern, cytotoxic T-cell (CTL) responses...
متن کاملMarker rescue of adeno-associated virus (AAV) capsid mutants: a novel approach for chimeric AAV production.
Marker rescue, the restoration of gene function by replacement of a defective gene with a normal one by recombination, has been utilized to produce novel adeno-associated virus (AAV) vectors. AAV serotype 2 (AAV2) clones containing wild-type terminal repeats, an intact rep gene, and a mutated cap gene, served as the template for marker rescue. When transfected alone in 293 cells, these AAV2 mut...
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 کاملInteraction of wild-type and mutant adeno-associated virus (AAV) Rep proteins on AAV hairpin DNA.
Both the Rep68 and Rep78 proteins of adeno-associated virus type 2 (AAV) bind to AAV terminal repeat hairpin DNA and can mediate site-specific nicking in vitro at the terminal resolution site (trs) within the terminal repeats. To define the regions of the Rep proteins required for these functions, a series of truncated Rep78 derivatives was created. Wild-type and mutant proteins were synthesize...
