Abstract:
:The cellular requirements for the in vitro induction of antigen-specific suppressor T cells were examined. Previous reports indicated that Ia-bearing macrophages and anti-idiotypic B cells are required as accessory cells to facilitate the generation of suppressor effector (TS3) cells which regulate the response to the 4-hydroxy-3-nitrophenyl acetyl (NP) hapten. The present study describes two distinct T cell populations which interact to generate antigen-specific TS3. Fractionation of the T cell populations with monoclonal antibody to the L3T4 determinant led to the identification of an NP-specific L3T4- TS3 progenitor population and an L3T4+ helper/inducer subset. In the presence of NP-coupled antigen, the L3T4+ subset could induce progenitor TS3 to differentiate into mature TS3 cells. The activity of the L3T4+ inducer population could be replaced with specifically activated cloned helper cells which were not NP-reactive since an I-Ab-restricted, insulin-reactive, L3T4+ clone was capable of supporting the generation of NP-specific TS3. Inducer activity appeared to be confined to the Th1 but not the Th2 subset. In addition, 18-hr supernatants from antigen-activated clones were capable of substituting for L3T4+ cells or T cell clones in TS3 induction cultures. The TS maturation/differentiation factor(s) active in these supernatants does not appear to be IL-1, IL-2, IL-3, or interferon-gamma alone since purified sources of these lymphokines failed to induce TS3 activity.
