title: The induction of TNP-altered, self-reactive human cytotoxic T cells by soluble factors: the role of Ia antigens.
abstract: This report demonstrates that human peripheral blood T lymphocytes, triggered by allogeneic cells or soluble antigens, elaborate helper factor(s) that promotes the in vitro differentiation of TNP altered-self reactive human CTL. Helper factor(s) alone is not sufficient for the generation of these killer cells, but requires the presence of TNP-derivatized autologous stimulators during sensitization. Additional experiments were performed with antisera to a human Ia-like antigen, p23, 30. These studies indicate that human Ia-like antigens play an important role in both the induction of helper factor(s) and in the functional activity of preformed helper factor(s) molecules.
