Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is ***,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the activation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)***,PZH stimulated signal transducer and activator of transcription 3(stat3)phosphorylation to induce the expression of a20,which could inhibit the activation of NF-κB and MAPK *** of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on stat3 phosphorylation and a20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by activating ***,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-stat3 and a20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory ***,our study identifies BAs as the effective components in PZH that activate TGR5-stat3-a20 signalling to ameliorate LPS-induced sepsis.
