The addition of concanavalin A to mouse spleen cell suspensions can either inhibit or stimulate the immune response to heterologous erythrocytes according to the experimental conditions. Evidence is presented which is incompatible with the hypothesis that these two effects are mediated by a single cell and which favors the hypothesis of separate inhibitor and stimulatory cells.
