Primary as well as secondary proliferative and cytotoxic responses to 2,4,6-trinitrophenyl (TNP)-modified autologous human cells have been studied. Proliferative responses have been obtained both by primary (peak on day 6) and secondary (peak on day 2--3) stimulation. Both responders and nonresponders were found among the panel of unrelated individuals tested. All responders in a secondary reaction also gave significant primary responses. Intrafamilial studies showed that the ability to restimulate a proliferative response followed the major histocompatibility complex haplotype of the responder; in some cases, the two haplotypes differed in their ability to restimulate. Using unrelated individuals typed for HLA-A, B and C, as well as HLA-D and DR, proliferation was shown to occur only when the unrelated stimulator shared HLA-D region products with the responder. In contrast, no HLA restriction was found in cell-mediated lympholysis (CML) (neither in primary nor in secondary responses) in most cases. The data suggest that the observed killing is independent of sensitization. Both responders and nonresponders in proliferation yielded high levels of lysis; no increase of lysis was found in kinetic studies; most allogeneic CML combinations were highly lytic for the TNP-modified responder cells at a time when the lysis of the specific allogeneic target is negligible. These preliminary data suggest that the killing observed might be different from classical T cell-mediated lympholysis.
