黄斑前膜(ERM)是一种以发生于视网膜内表面的纤维细胞膜为特征的视网膜疾病。现有的临床指南及文献资料对ERM的诊断与治疗已基本达成共识,但对其机制的阐述仍众说纷纭。转化生长因子-β(TGF-β)是一种高度多效性的细胞因子,在伤口愈合、血管生成、免疫调节、癌症、炎症及纤维化疾病中起着重要作用,越来越多的研究表明,ERM是玻璃体后脱离(PVD)引起视网膜发生炎性损伤以及视网膜色素上皮层细胞等细胞经历上皮间质转化(EMT)所致纤维化的一类病理改变,而多种细胞因子通过参与非经典的TGF-β-Snail途径与经典的TGF-β-Smad途径调控TGF-β介导的EMT进程。目前已有部分针对上述途径相关细胞因子的药物进入研发阶段,对提供ERM临床治疗及预防新思路具有重要意义。本文就TGF-β在ERM形成中相关细胞因子的研究进展作一综述。

[Abstract]
Epiretinal membrane(ERM)is a retinal disease characterized by a fibrocell membranes that can develop on the inner surface of the retina. The existing clinical guidelines and literature have reached a consensus on the diagnosis and treatment of ERM, but the explanation of their mechanism is still controversial. Transforming growth factor-β(TGF-β)is a highly pleiotropic cytokine that plays an important role in wound healing, angiogenesis, immune regulation, cancer, inflammation and fibrosis diseases. Studies have increasingly shown that ERM is a kind of pathological changes in fibrosis that caused by the posterior vitreous detachment(PVD)and lead to the retinal inflammatory damage and epithelial to mesenchymal transition(EMT)of retinal pigment epithelial cells. A variety of cytokines regulate TGF-β-mediated EMT process by participating in the non-classical TGF-β-Snail pathway and the classical TGF-β-Smad pathway. At present, some drugs targeting cytokines related to the above pathway have entered the development stage, which is of great significance to provide new ideas for clinical treatment and prevention of ERM. This review reviews the progress of TGF-β related cytokines in ERM formation.
