  [背景与目的]肝纤维化是各种慢性肝病向肝硬化、肝癌发展的必经阶段。虽然肝纤维化发病率高,但对其发病机制尚不完全清楚,且无有效的抗纤维化治疗手段。本研究通过创建CCl4诱导的小鼠肝脏纤维化模型,研究FKBP51在肝脏纤维化中的作用,以期研究肝脏纤维化的发生机理,并为寻找预防和治疗肝脏纤维化提供新的靶点。

[目的]FKBP51是一种具有肽基脯氨酰顺-反异构酶(PPIase)活性的免疫亲和蛋白,它含有多肽重复序列结构域(TPR),能够介导蛋白与蛋白之间的相互作用。已有研究表明,FKBP51在脂肪生成中发挥重要的作用。因此,我们通过对FKBP51基因敲除小鼠表型的分析,来探究FKBP51的缺失与肥胖的关系。
