Genetic control of lymphocyte suppression. I. Lack of suppression in aged NZB mice is due to a B cell defect.

Con A-activated cells from old NZB mice were found capable of inhibiting the polyclonal response of cells from young NZB and BALB/c animals. Furthermore, Con A-preactivated spleen cells from young NZB and BALB/c mice did not significantly affect the response of spleen cells from old NZB mice. These results suggest that the defective suppressive activity in… CONTINUE READING
