Adeno-associated virus (AAV) vectors are currently in use in a number of Phase I/II clinical trials as delivery vehicles to target a 15900046 variety of tissues to achieve sustained expression of therapeutic genes [1,2,3,4,5]. However, large vector doses are needed to achieve therapeutic benefits. The requirements for sufficient amounts of the vector pose a production challenge, as well as the risk of initiating the host immune response to the vector [6,7,8]. More specifically, recombinant vectors based on AAV2 serotype were 1531364 initially used in a clinical trial for the potential gene therapy of hemophilia B, but in this trial, therapeutic level of expression of human Factor IX (hF.IX) was not achieved at lower vector doses, and at higher vector doses, the therapeutic level of expression of hF.IX was short-lived due to a cytotoxic T cell (CTL) response against AAV2 capsids [9,10,11]. In a more recent trial with recombinant vectors based on AAV8 serotype, therapeuticlevels of expression of hF.IX were been achieved, but an immune response to AAV8 capsid proteins was observed [12]. Thus, it is critical to develop novel AAV vectors with high transduction efficiency that can be used at lower doses. We have previously reported that cellular epidermal growth factor receptor protein tyrosine kinase (EGFR-PTK) negatively impacts transgene expression from recombinant AAV2 vectors primarily due to AN 3199 web phosphorylation of AAV2 capsids at tyrosine residues, and tyrosine-phosphorylated capsids are subsequently degraded by the host proteasome machinery [13,14]. In our more recent studies [12], we observed that selective inhibitors of JNK and p38 MAPK serine/threonine kinases also improve the transduction efficiency of AAV2 vectors, suggesting that phosphorylation of certain surface-exposed serine and/or threonine residues might also decrease the transduction efficiency of these vectors. These studies led to the development of tyrosine- and serine-mutantLimits of Optimization of Recombinant AAV2 VectorsAAV2 vectors, which we subsequently documented to transduce various cell types with significantly higher efficiency than the WT vectors [12,13,14,15]. We hypothesized that in addition to the tyrosine and serine residues, the elimination of surface-exposed threonine residues by site-directed mutagenesis, might also lead to an increase in the transduction eff.YH real-time PCR.down-regulated in both iE2 and E2 as compared to their controls in the absence of ethanol stress.
