Strategies to generate high-titer, high-potency recombinant AAV3 serotype vectors.

ABSTRACT: Although recombinant adeno-associated virus serotype 3 (AAV3) vectors were largely ignored previously, owing to their poor transduction efficiency in most cells and tissues examined, our initial observation of the selective tropism of AAV3 serotype vectors for human liver cancer cell lines and primary human hepatocytes has led to renewed interest in this serotype. AAV3 vectors and their variants have recently proven to be extremely efficient in targeting human and nonhuman primate hepatocytes in vitro as well as in vivo. In the present studies, we wished to evaluate the relative contributions of the cis-acting inverted terminal repeats (ITRs) from AAV3 (ITR3), as well as the trans-acting Rep proteins from AAV3 (Rep3) in the AAV3 vector production and transduction. To this end, we utilized
