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.
