Geniposide via enema alleviates colitis by modulating intestinal flora and bile acid metabolites, inhibiting S100A8/S100A9/NF-κB, and promoting TGR5 inhibition of NLRP3 inflammasome
We firstly confirmed that GE alleviates UC via the enema route in a better manner than the oral route, through enhancing the intestinal barrier, restoring intestinal flora and BAs homeostasis, and inhibiting inflammatory injury. This study initially revealed that GE can alleviate UC through elevating UDCA, DCA, and LCA levels at the colonic site to activate TGR5 receptor for inhibiting the NLRP3 inflammasome, in addition to downregulating the S100A8/S100A9/-TLR4-NF-κB pathway related inflammatory response directly. The evidences offer a promising strategy and profround meaning for UC treatment.
