we report that ( a ) antigen is not reprocessed by the eye for the induction of suppression in tnp-acaid , ( b ) the t cells injected into the ac and the recipient animal must match at genes in the immunoglobulin heavy chain ( igh ) region of chromosome xii for tnp-acaid to be induced , ( c ) tnp-coupled lyt-1+ , i-j+ t cells present antigen to viable t cells within the eye to induce systemic suppression , ( d ) although there is an igh restriction between the t cells injected into the ac and the recipient , the interaction between the t cell antigen-presenting cell and the tsi-cells in the ac inoculum is restricted to the i-j portion of the major histocompatibility complex , and ( e ) the two tsi-cells that initiate the suppressor cascade have different antigen presentation requirements .
