Abstract
The simian immunodeficiency virus (SIV) model of AIDS is widely used for the development of human immunodeficiency virus (HIV) vaccine strategies, particularly for the analysis of correlates of protective immunity. As it is not always possible to establish autologous B-lymphoblastoid cell lines (B-LCL) for use as targets in the analysis of cytotoxic T cell (CTL) activity, we have compared B-LCL with primary simian skin cells. Using a well-defined SIV gag-encoded CTL epitope restricted by Mamu A*01 major histocompatibility complex (MHC) class I, we have shown that peripheral blood mononuclear cells (PBMC) from vaccinated and infected macaques can kill MHC class I-matched skin fibroblasts presenting the cognate epitope but that skin fibroblasts are a less sensitive target than B-LCL for the detection of CTL.
