Abstract

A CD4+ cytotoxic T-lymphocyte (CTL) clone, established from the peripheral blood of a human immunodeficiency virus (HIV)-seropositive donor, lysed autologous target cells that were infected with a recombinant vaccinia virus containing the gag gene of HIV type 1 and target cells pulsed with p24gag construct expressed in Escherichia coli. The recognition of the HLA-DQ-restricted epitope by this clone was further defined by using overlapping synthetic peptides. The epitope recognized by this CD4+ CTL clone (amino acids 140 to 148) overlaps with a CD8+ epitope and is highly conserved among all isolates of HIV type 1 that have been sequenced. Production and secretion of lymphokines such as interleukin-2 and interleukin-6 after specific antigenic stimulation were demonstrated by this gag-specific CD4+ CTL clone.
