Abstract
In transgenic mice, mature peripheral B lymphocytes in lymphoid follicles, like immature B cells, are rendered tolerant by encounter with self-antigen, provided receptor occupancy by self-antigen exceeds a critical threshold. The tolerant state of the B cell is closely correlated with down-regulation of membrane IgM but not IgD antigen-receptors. Identical changes in antigen-receptor expression occur in a subset of follicular B cells in nontransgenic mice, suggesting that clonally silenced self-reactive cells are common in the peripheral B-cell repertoire.
