abstract：:HIV-1 positive patients generate Nef-specific CTL response, indicating that Nef is a potent immunogen. However, Nef is also known to down regulate the expression of CD4 and MHC-I molecules, thereby protecting virally infected target cells. We compared the immunogenicity of non-functional nef vaccine constructs to wild...
