Mechanism of Daifan Powder (黛矾散) regulating cGAS/STING signaling pathway to medicate immune inflammation to improve intrahepatic bile duct injury in primary biliary cholangitis
Abstract
目的 探讨黛矾散调控环鸟苷酸-腺苷酸合成酶(cGAS)/干扰素基因刺激蛋白(STING)通路影响免疫炎症,改善原发性胆汁性胆管炎(PBC)肝内胆管损伤的机制。 方法 C57BL/6小鼠分为对照组,模型组,熊去氧胆酸(100 mg kg-1)组,黛矾散低、中、高剂量(90,180,360 mg kg-1)组,造模后给药,连续灌胃28 d。测定小鼠肝脏指数;检测生化指标γ-GT、TBA、TBIL、AST、ALT含量;观察肝组织病理学改变;ELISA法检测TNF-α、IL-6、IL-1β、IFN-β、IL-17A含量;RT-PCR法检测cGAS、STING mRNA水平;WB法检测cGAS、STING、TANK结合激酶(TBK1)、p-TBK1、干扰素调节因子3(IRF3)、p-IRF3、NF-κB、p-NF-κB水平。 结果 与对照组比较,模型组肝指数升高(P
