Core Tip

Core Tip: As the precursor of B cells, the activation of memory B cells can trigger the activation of B cells, thus producing numerous inducible B cells and tolerant B cells, whose dysfunction can easily result in inflammatory bowel disease (IBD). Also, the disorder of humoral immune function mediated by memory B cells has a critical position in the pathogenesis of IBD. As an immune suppressant, curcumin (Cur) has a therapeutic role in treating many immune diseases, such as IBD and rheumatoid arthritis. Meanwhile, it has proven efficacy in experimental colitis mice and patients with ulcerative colitis (UC), while the disturbances in memory B cells have been observed in IBD. However, few studies have explored whether Cur treatment of colitis is closely related to memory B cells. In the present research, our results indicated that Cur effectively alleviated DSS-induced UC in mice via a potential mechanism involving memory B cells and the Bcl-6-Syk-BLNK signaling pathway.
