Core Tip

Core Tip: Memory T cells (mTh) are formed by the differentiation of initial T cells following antigenic stimulation and have a long lifespan. The dysfunction and out-of-balance of mTh and their subsets destroy immune homeostasis to induce autoimmune diseases including inflammatory bowel disease. Finding new drugs for inflammatory bowel disease (IBD) treatment from natural plant medicine and traditional Chinese medicine is a research hotspot. Cur can regulate memory B cells and other immune cells to effectively treat experimental colitis. However, whether Cur can regulate mTh cell- and mfTh cell-mediated homeostasis to treat IBD remains unclear. We here indicated that Cur regulates the mTh/memory follicular T helper cell homeostasis to reduce dextran sulfate sodium-induced colonic pathological injury, which may be achieved by inhibiting the JAK1/STAT3/SOCS signaling pathway.
