Research Abstract |
Strong and broad HIV-specific CTLs are induced against numerous targets (epitopes) during HIV infection. In this study, we demonstrates a mechanism, which generates de novo CTL epitope after one amino acid change that might result from the CTL pressure to the overlapping epitope. This novel “epitope switching” mechanism that occurs in host immunity might help the understanding of cellular immunity and CTL vaccine development.
