title: Nature of the antigenic complex recognized by T lymphocytes. V. Genetic predisposition of independent F1 T cell subpopulations responsive to antigen-pulsed parental macrophages.
abstract: Nonimmune (2 x 13)F1 guinea pig T lymphocytes initially stimulated with trinitrophenyl- (TNP) modified macrophages from one parental strain and then treated with bromodeoxyuridrine (BUdR) and light are unable to be primed subsequently with TNP-modified macrophages of the same parental strain. In contrast, these BUdR and light treated F1 T cells can be primed with TNP-modified macrophages of the other parental strain. These results demonstrate that in a nonimmune F1 animal two T cell subpopulations exist before priming that are genetically predisposed to respond to antigen associated with macrophages derived from one or the other parent.
