Abstract: | The immunogenic and tolerogenic activities of solubilized T2 phage antigens in a primary in vitro response are augmented when these antigens are presented in cell-bound form. This enhancement is shown to be effected equally by an antigen adsorbed to autologous cells, to cells matched or mismatched with respect to major histocompatibility antigens, or to xenogeneic cells. Spleen or lymph node cells are more effective carriers of adsorbed T2 antigens than are thymocytes or erythrocytes. Among lymphocytes, T cells are more effective than B cells. Erythrocytes and B lymphocytes also are shown to bind significantly less solubilized T2 proteins than do T lymphocytes or thymocytes. |
