Abstract:
:The induction characteristics of major histocompatibility complex (MHC) class I-specific cytotoxic T lymphocytes (CTL) after footpad immunization were studied. Primary CTL were generated in the regional lymph nodes of C57Bl/6 mice by footpad injection with 10(7) irradiated (2000 rad) spleen cells from MHC class I mutant mouse strain (bm1) followed by a short in vitro culturing without antigen. The requirement of accessory cells and L3T4+ T cells during in vitro maturation of in vivo primed CTL precursor (CTLp) was shown. Moreover, using inhibitory antibodies, the need for IL-2 and IL-4 for in vitro maturation of CTL was established. We have suggested that accessory cells act at the level of L3T4+ T cells which in turn non-specifically up-regulate the CTL response through the production of growth and differentiation factors. Thus, the T-helper population of L3T4+ but not Lyt2+ phenotype appears to be recruited in the in vitro maturation of in vivo primed CTLp in a given system. Possible mechanisms of this phenomenon are discussed.

Cell surface molecules may stimulate autoreactive T-helpers if class II MHC is expressed; special factors may predispose to the ease of class II induction.
