The proliferation and development of cytotoxic T cells was investigated in human peripheral blood mononuclear cell (PBMC) cultures stimulated with an antigenic extract from Candida albicans (MPPS), or with the purified protein derivative from Mycobacterium tuberculosis (PPD), or with human recombinant interleukin 2 (rIL-2). Microbial antigen- and rIL-2-induced cytotoxic T cells were able to lyse both natural killer (NK) sensitive and resistant targets. No correlation was observed between the development of T cell cytotoxicity and interferon (IFN) production in vitro. The addition of anti-class II monoclonal antibodies at the beginning of MPPS/PPD-stimulated cultures inhibited the cell proliferation, IFN production and T cell cytotoxicity, while all these cellular activities were not inhibited by anti-class II antibodies in rIL-2-stimulated cultures. Finally, antibodies to class I determinants inhibit T cell cytotoxicity, suggesting a role of such determinants in the development of the non-adaptive immunity to microbial infections.
