英文摘要
In the autoimmune disease, auto-reactive B cells are activated and produce theautoantibodies, which induce the tissue injury. We found that abnormal expression of G5PR,one of the B’’ regulatory subunit of the serine/threonine protein phosphatase 2A,induced the expansion of B-1a cells in the peritoneal cavity and generation ofautoantibodies in mice. Over-expression of G5PR in B-1a cells suppressed the JNK-mediatedapoptotic signal pathway and rescued from activation-induced cell death by antigenstimulation. These results suggest that G5PR may play a pivotal role in B cell selectionfor B-1a cells and in the development of autoimmune disease.
