摘要
Bile acids(BAs)are synthesized by the host liver from cholesterol and are delivered to the intestine,where they undergo further metabolism by gut microbes and circulate between the liver and intestines through various transporters.They serve to emulsify dietary lipids and act as signaling molecules,regulating the host’s metabolism and immune homeostasis through specific receptors.Therefore,disruptions in BA metabolism,transport,and signaling are closely associated with cholestasis,metabolic disorders,autoimmune diseases,and others.Botanical triterpenoids and steroids share structural similarities with BAs,and they have been found to modulate BA metabolism,transport,and signaling,potentially exerting pharmacological ortoxicological effects.Here,we have updated the research progress on BA,with a particular emphasis on new-found microbial BAs.Additionally,the latest advancements in targeting BA metabolism and signaling for disease treatment are highlighted.Subsequently,the roles of botanical triterpenoids in BA metabolism,transport,and signaling are examined,analyzing their potential pharmacological,toxicological,or drug interaction effects through these mechanisms.Finally,a research paradigm is proposed that utilizes the gut microbiota as a link to interpret the role of these important natural products in BA signaling.
