Abstract:非酒精性脂肪性肝病(non-alcoholic fatty liver disease,NAFLD)是西方国家最常见的慢性肝脏疾病,其疾病谱包括肝脂肪变性,脂肪性肝炎,进一步的肝纤维化、肝硬化,甚至肝细胞性肝癌.其发病机制尚未明确,通常解释为“二次打击”学说.然而新的研究发现非甘油三酯在肝脏的沉积,而是脂肪酸(fatty acids,FAs)及其代谢产物等可能对肝脏有毒性作用.过氧化物酶体增殖物激活受体(PPARs)是配体激活的转录因子,是核受体超家族成员之一,具有调节脂质及糖代谢、抗炎和抗纤维化作用,尤其在FAs储存及分解代谢中起到核心作用,与NAFLD的发生发展密切相关,可能作为治疗NAFLD有效靶点.本文将对PPARs在NAFLD发病机制中的作用做一综述.
