- Asiaticoside ameliorates DSS‐induced colitis in mice by inhibiting inflammatory response, protecting intestinal barrier and regulating intestinal microecology Kunjian Liu Yu Yin Chong Shi Chengqiu Yan Yiwen Zhang Li Qiu Shuangyan He Guofeng Li Phytotherapy Research AbstractUlcerative colitis (UC) is one of the most prevalent inflammatory bowel diseases and poses a serious threat to human health. Currently, safe and effective preventive measures are unavailable. In this study, the protective effects of asiaticoside (AS) on dextran sodium sulfate (DSS)‐induced colitis in mice and the underlying molecular mechanism were investigated. In this experiment, colitis was induced in mice with DSS. Subsequently, the role of AS in colitis and its underlying mechanisms were examined using H&E staining, immunofluorescence staining, western blot, Elisa, FMT, and other assays. The results showed that AS significantly attenuated the related symptoms of DSS‐induced colitis in mice. In addition, AS inhibited the activation of signaling pathways TLR4/NF‐κB and MAPK reduced the release of inflammatory factors, thereby attenuating the inflammatory response in mice. AS administration also restored the permeability of the intestinal barrier by increasing the levels of tight junction‐associated proteins (claudin‐3, occludin, and ZO‐1). In addition, AS rebalanced the intestinal flora of DSS‐treated mice by increasing the diversity of the flora. AS can alleviate DSS‐induced ulcerative colitis in mice by maintaining the intestinal barrier, thus inhibiting the signaling pathways TLR4/NF‐κB and MAPK activation, reducing the release of inflammatory factors, and regulating intestinal microecology. 10.1002/ptr.8129 http://onlinelibrary.wiley.com/termsAndConditions#vor
