title: Generation of H-2-reactive T cell lines that bear the 5936 idiotype(s).
abstract: The present experiments showed 1) that it was possible to produce mouse T cell lines against MHC determinants with a relatively high success rate by stimulation of purified T cells with allogeneic cells in the presence of irradiated syngeneic spleen cells; 2) that these lines could be led to react against selected H-2 specificities; 3) that only T cell lines established from Ig-1b allotype mice contained 5936-Id+ T cells (5936-Idiotypes are defined by an antiserum against B6 anti-CBA IgG produced in rabbit no 5936, which was tolerant to mouse gamma-globulin); and 4) that antigenic determinants coded by IAk genes induce the 5936-Idiotype(s). The latter data are in accordance with the 5936-idiotype characteristics of primary MLC T blasts. All T cell lines contained both specific MLC-responding cells and cytolytic cells. However, studies on the functional capacity of 5936-Id+ T cells from both primary MLC and the T cell lines showed that neither MLC-responding cells nor cytolytic cells directed against H-2Kk, IAk, or H-2Dk were 5936-Id+. Thus, 5936-Id+ T cells may be regulator cells induced by IAk antigens.
