Suppression of intestinal Ticam1 ameliorated MASH via Akkermansia muciniphila QAA37749.1 mediated betaine transformation

Gut inflammation caused by diets could damage the intestinal barrier, which increases the liver exposition to pathogenic substances. Toll-IL-1 receptor (TIR) domain-containing adaptor molecule-1 (Ticam1) is a key molecule in the Toll-like receptors (TLRs) pathway, which is important for the immune defense against pathogens such as bacteria or viruses. In this study, mouse intestinal epithelial cell (IEC) Ticam1 was knocked out to suppress the intestinal inflammation response in metabolic dysfunction-associated steatohepatitis (MASH) to investigate its influence on the development of MASH.
