Abstract

We studied the cellular basis for the induction of Ts cells in anterior chamber (AC)-associated immune deviation (ACAID) by using TNP-modified syngeneic spleen cells (TNP-Spl). We demonstrate that the cells responsible for the induction of TNP-ACAID are non adherent, IA- T cells. This is in contrast to the antigen-presenting cells which induce suppression after the i.v. injection of TNP-Spl which are IA+/I-J+ adherent cells. Furthermore, two T cells which the TNP-Spl population are required to initiate suppression in TNP-ACAID: one is Lyt-1+, and I-J+, the other is Lyt-1+ and reactive with a monoclonal antibody, 14-30, which specifically identifies Ts inducer cells. The antigen specificity of ACAID resides in the 14-30+ T cell, and not the I-J+ cell. Although both cells must be viable to induce suppression, neither they (nor their products) must be in direct contact within the eye; one population may be in the right AC, the other in the left. Our results suggest that it is Ts inducer cells placed into the AC of the eye which initiate TNP-ACAID, and that these cells exit (or secrete Ts factors which exit) the eye to induce Ts effector cells in the spleen.
