title: Lack of cross-reaction in antibody-dependent cellular cytotoxicity between human immunodeficiency virus (HIV) and HIV-related West African strains.
abstract: Sera from individuals infected with human immunodeficiency virus (HIV) and HIV-related West African viruses can mediate high-titered, virus-specific antibody-dependent cellular cytotoxicity (ADCC) in all stages of infection. No cross-reactive ADCC can be detected between HIV and HIV-related West African strains LAV-2, HTLV-IV, and SBL-6669. Because these two groups of viruses have antigenically distinct envelope glycoproteins, ADCC-mediating antibodies are most likely directed against envelope antigens. For HIV-specific ADCC, this was further confirmed by using sera reacting with HIV envelope but negative for antibodies against viral core antigens.
