Differentiation of B cells into plasma cells represents a critical immunoregulatory checkpoint where neutralizing Abs against infectious agents mast be selected whereas self-reactive Abs are suppressed. Bacterial LPS is a uniquely potent bacterial immunogen that can bypass self-tolerance within the T cell repertoire. We show here that during LPS-induced plasma cell differentiation, the ERK intracellular signaling pathway serves as a pivotal switch integrating opposing inputs from Ag via BCR and...[Show more]
