    摘要: The present invention relates to methods and compositions for increasing the production of high titer stocks or recombinant AAV (rAAV) through regulation of expression of the AAV REP and CAP proteins. The methods and compositions of the invention are based on the observation that the low level expression of the AAV REP 78/68 protein increases the production of AAV viral capsid protein and efficiency of packaging resulting in production of higher titer recombinant viral stocks. The invention encompasses recombinant AAV vectors that direct the expression of AAV REP and CAP proteins and the use of such vectors for the production of novel stable cell lines capable of generating high titer rAAV vectors. The invention provides methods for regulating the expression of the AAV REP 78/68, REP 40/52 and CAP gene at the transcriptional and post-transcriptional level.
