Negatively selected mouse and rat lymphocyte populations, specifically deprived of alloreactivity to a particular major histocompatibility complex (MHC) haplotype, are nevertheless fully capable of responding to trinitrophenyl (TNP)-modified allogeneic stimulator cells and developing cytotoxic T-lymphocyte activity to TNP-altered allogeneic target cells. As for syngeneic systems, lytic expression of those responder killer cells also requires MHC identity between the target and stimulator cell populations. Such a finding argues strongly against two variations of the dual recognition hypothesis: like-like interactions and adaptive differentiation. Instead, these data favor either the altered self model or a third variation of the dual receptor model, where one of the relevent receptors is specific for the modifying antigen and the second is a low affinity receptor unable to be triggered in the absence of a modifying antigen.

The generation of killer cells to trinitrophenyl-modified allogeneic targets by lymphocyte populations negatively selected to strong alloantigens.
