 AB    An HIV-1-seropositive volunteer was infused with an expanded autologous
       cytotoxic T lymphocyte (CTL) clone directed against the HIV-1 nef
       protein. This clone was adoptively transferred to determine whether
       supplementing CTL activity could reduce viral load or improve clinical
       course. Unexpectedly, infusion was followed by a decline in circulating
       CD4+ T cells and a rise in viral load. Some of the HIV isolates obtained
       from the plasma or CD4+ cells of the patient were lacking the nef
       epitope. These results suggest that active CTL selection of viral
       variants could contribute to the pathogenesis of AIDS and that clinical
       progression can occur despite high levels of circulating HIV-1-specific
       CTLs.
