 AB    To generate CD4+ T-helper cell lines, lymphocytes from HIV-seronegative
       subjects were primed in vitro with peptides derived from the V3 loop of
       HIV-1 gp120. Antigen-specific reactivity was inhibited by an anti-DR
       monoclonal antibody, indicating HLA-class II dependency, but peptides
       could be recognized in different HLA-class II contexts. Three sites on
       V3LAI and two on V3MN were identified as targets of the respective
       V3LAI- and V3MN-specific lines. Recognition of V3 peptides was
       isolate-specific. The lines did not react against whole gp160, which
       suggests that V3 may be differently presented when used as such rather
       than as part of the entire glycoprotein. Similar results were obtained
       in chimpanzees immunized in vivo against V3LAI.
