肾纤维化信号通路的中医药研究进展

摘要肾纤维化可表现为肾小球硬化、肾小管-间质纤维化、肾血管硬化及肾细胞外基质(ECM)堆积,与炎性细胞浸润,促炎因子分泌异常,以及肾脏固有细胞的损伤、活化,增殖,凋亡密切相关。肾纤维化涉及包括TGFβ1-Smad、MAPK、Wnt/β-catenin、

PI3K/Akt/mTOR等多条信号通路,共同的效应分子又使各通路间有串话机制,目前尚无有效

的药物控制。近10年来中医药在防治肾纤维化方面积累了丰富的经验,肾纤维化信号通路研究也成为筛选和研究中药作用机制和靶点手段。

Abstract Renal fibrosis can be manifested as glomerular sclerosis,renal tubulointerstitial fibrosis,renal vascular sclerosis and renal extracellular matrix(ECM)accumulation,with inflammatory cell infiltration,abnormal secretion of pro-inflammatory factors,and damage to the kidney′s natural cells,activation,proliferation,and apoptosis are closely related.Renal fibrosis involves multiple signaling pathways including TGFβ1-Smad,MAPK,Wnt/β-catenin,and

PI3K/Akt/mTOR,etc.The common effector molecule has a crosstalk mechanism between the pathways,and there is no effective drug to control.In the past 10 years,traditional Chinese medicine has accumulated rich experience in the prevention and treatment of renal fibrosis.The research on renal fibrosis signaling pathway has also become a mechanism and target means for screening and studying traditional Chinese medicine.

肾纤维化(Renal Fibrosis,RF)是各种原因引起的慢性肾脏疾病(Chronic Kidney Disease,CKD)进展成为终末期肾病(End Stage Renal Disease,ESRD)是共同途径。既往的研究表明无论是肾小球硬化,肾小管-间质纤维化、肾血管硬化及肾细胞外基质(Extracellular Matrix,ECM)堆积,其核心病理环节主要与炎性细胞浸润,促炎因子分泌异常,以及肾脏固有细胞的损伤、活化,增殖,凋亡相关。RF是慢性炎性反应损伤过程,也是各类细胞因子、免疫细胞、炎性反应递质与肾脏固有细胞共同参与过程,其中细胞因子参与各类信号通路转导,胞核基因转录调控是RF主要原因之一。中医中药作用多靶点,多途径,近年来一些补气活血,解毒泄浊类的单方,验方在防控RF治疗方面积累了丰富的经验[1],现综述如下。
