| Research Abstract |
Under bacterial translocation, expressions of inflammatory cytokines (TNFα、NF-κB et al.) and Toll like receptor (TLR) 2, 4 were increased and caused apoptosis. Tight Junction (TJ) protein (Claudin-1・4、Occludin et al.) were decreased. Diversity of microbiome was decreased and Akkermansia, which disturbed intestinal epithelium, was appeared. Herbal medicine (TU-100) decreased inflammatory cytokines and TLR 2, 4 and maintained TJ proteins and diversity of microbiome, which intoruduced Blautia having protective effects of intestinal epithelium.
