Abstract

I-A+/I-J+ cloned macrophages, SL-1, played the role of APC in the in vitro induction of Ts against DTH to BCG. By treating SL-1 cells with various antibodies, it was shown that I-J antigens on SL-1 cells are essential for Ts induction, but not for the effector cell induction for DTH. Ia-negative cloned macrophages, SL-4, did not show any APC activity either in suppressor or effector cell induction. The precursors of the Ts were also I-J-positive, and I-J restriction resided between T cells and macrophages in the Ts induction. Thus, it is suggested that the pre-Ts recognizes the antigenic determinants of BCG presented on the APC in association with the I-J antigen and differentiates into the Ts. This pathway seems analogous to that of helper or effector T induction, where the antigenic determinant is recognized by a T cell in association with the I-A antigen on APC.
