 AB    HIV-I-specific, MHC-restricted cytotoxic T cells may be detected
       directly in peripheral blood (PB) of HIV-1-infected patients, and
       cytotoxic T-cell lines can be established in vitro. CD8+ T cells
       predominate, and epitopes exist in most viral antigens. Generation of
       cytotoxic T cells from the PB mononuclear cells from uninfected donors
       has received less attention. Our aim is to characterise the primary
       cellular immune response to HIV-1 infection in vitro. The approach is to
       generate T-cell colonies and amplify T-cell lines and clones. These
       T-cells are phenotyped (cell markers) and their HIV-1 specificity
       determined by use of autologous targets infected with HIV-1 or with
       vaccinia constructs expressing HIV-1 antigens. So far, 92 T-cell lines
       and 20 clones have been established in response to stimulation with live
       or inactivated HIV-1. Both CD4+ and CD8+ T cells have been generated.
       Cytotoxicity tests have so far yielded 6 T-cell lines with putative
       HIV-1 specificity for detailed study.
