肝纤维化是一个极为复杂的病理过程,其形成的关键环节是肝脏星状细胞(HSC)的活化并转化成为肌纤维样母细胞(MFB),进而合成、分泌大量细胞外基质(ECM),导致ECM代谢失衡.在人们所发现的哺乳动物转化生长因子β(transforming growth factor beta,TGF-β)超家族中,TGF-β1是其中的主要成员,它既能抑制肝细胞、内皮细胞、上皮细胞的增殖,诱导细胞外基质的形成,又可以诱导肝细胞凋亡,是HSC向MFB转化进程中最重要的促进因子.因此,抑制TGF-β1生成,从分子水平阻断TGF-β1的信号转导,才有可能从"源头"上中止肝纤维化的形成.本文将从抑制TGF-β1的产生,阻断其与受体结合以及调控其胞内信号转导过程三个方面对近年来转化生长因子β1与肝纤维化的实验性基因治疗研究状况作一综述.
