T-cell-mediated suppression of the antibody response of autoimmune NZB/N mice to Type III pneumococcal polysaccharide (SSS-III) can readily be induced in situ by priming with a subimmunogenic dose of SSS-III; however, the transfer of either "young" (8 weeks old) or "old" (42 weeks old) SSS-III-primed B cells, which activates suppressor T cells in normal BALB/cByJ mice, fails to induce suppression of the antibody response in recipient NZB/N mice, regardless of the number of cells transferred or the time interval between transfer and immunization. Transfer of 51Cr-labeled B cells demonstrated that syngeneic primed B cells home to the spleens of NZB/N mice in somewhat lower numbers than in BALB/cByJ mice, although the differences observed may not be sufficient to explain the complete absence of activation of suppressor T cells. These findings suggest that B cells from autoimmune NZB/N mice are unable to activate T suppressor cells upon transfer; this disorder in a normal regulatory mechanism may be important in the pathogenesis of disease.
