PG - 281-286 LID - S1567-5769(18)30458-2 [pii] LID - 10.1016/j.intimp.2018.12.007 [doi] AB - As antigen-presenting cells (APC), B cells exert a variety of immune regulatory functions mainly by presenting antigens, triggering immune response, and producing antibodies for immune regulation. Regulatory B cells (Bregs) are special subpopulations of B cells with immune-regulating or immune-suppressing properties and play a role in peripheral tolerance. Bregs suppress immune response through inhibiting the differentiation of dendritic cells (DCs), suppressing the proliferation of helper T1(TH1) cells and helper T17 (TH17) cells, inducing the differentiation of fork head transcription factor p3 positive regulatory T cells (FoxP3(+) Tregs). Different subsets of Bregs have distinct phenotypes and markers. Different subsets of Bregs participate in immune modulation by different ways. The absence or loss of Bregs exacerbates the severity of many disease such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and graft-versus-host-disease (GVHD). Bregs are also involved in tumor immunosuppressive effect and inhibit the antitumor immune process. In this article, we review the research advances of Bregs in autoimmune diseases, GVHD and tumor.
