Isodeoxycholic Acid is a secondary bile acid [1]. Isodeoxycholic Acid regulates bile acid synthesis, enterohepatic circulation, and energy metabolism, influencing the composition of the intestinal microbiome and inflammatory responses [2]. Isodeoxycholic Acid is primarily used to treat cholestasis, hepatobiliary diseases, and metabolic syndrome [3-4].
In CD4⁺T cells, Isodeoxycholic Acid (100μM; 3d) acts on dendritic cells, weakening their immunostimulatory properties and thereby enhancing the induction of Foxp3 [5].

Isodeoxycholic Acid是一种次级胆汁酸 [1]。Isodeoxycholic Acid调节胆汁酸合成、肠肝循环和能量代谢，影响肠道菌群的组成和炎症反应 [2]。Isodeoxycholic Acid主要用于治疗胆汁淤积、肝胆疾病和代谢综合征 [3-4]。
在CD4⁺T细胞中，Isodeoxycholic Acid（100μM；3d）作用于树突状细胞，削弱其免疫刺激特性，从而增强Foxp3的诱导 [5]。
