Core Tip
Core tip: Inflammatory bowel disease is a common autoimmune disorder characterized by chronic inflammation of the gastrointestinal tract. Abnormal immune cell responses contribute to the pathogenesis of the colitis. Probiotics are found to regulate the intestinal immune system and play a beneficial role in treating colitis. In our study, we showed that Bifidobacterium infantis (B. infantis) reduced the intestinal inflammation in TNBS-induced colitis mice though decreasing the Th1 and Th17 responses and promoting the Foxp3+ Treg response in mesenteric lymph nodes. This mechanism underlying the regulatory effect of B. infantis on the immune system may have significant clinical implications in treating inflammatory bowel disease and preventing colorectal cancer.
