Abstract
增生性玻璃体视网膜病变(proliferative vitreoretinopathy,PVR)是眼外伤和玻璃体视网膜手术的严重并发症,可导致严重的视力减退.血小板衍生生长因子(platelet derived growth factors,PDGF)及其受体(platelet derived growth factors receptor,PDGFR)在一系列生理过程中必不可少,这些过程对于机体正常的发育过程至关重要.但异常表达的PDGF及PDGFR能够激活下游信号通路,调控细胞异常增生、迁移等过程.PDGF是重要的有丝分裂原,眼外伤或孔源性视网膜脱离后血-视网膜屏障被破坏,PDGF从血小板α颗粒释放或由视网膜色素上皮细胞等自分泌,诱导细胞增生,增强细胞的迁移、侵袭、收缩能力,形成增生膜后可能进一步导致牵拉性视网膜脱离.玻璃体内含有PDGF家族以外的生长因子能够间接激活PDGFR足以导致PVR,阻滞PDGFR能够有效抑制PVR.
