摘要 后发性白内障(亦称后囊膜混浊)是白内障术后常见并发症,由术后残留的晶状体上皮细胞在囊膜上转分化、增生、移行,产生胶原所致。结缔组织生长因子(connectivetissuegrowthfactor,CTGF)在正常晶状体上皮细胞中不表达,而在前囊膜下型白内障及后囊膜混浊时大量表达,产生胶原,参与前囊膜下型白内障和后发性白内障的发生、发展过程。TGF(transforminggrowthfactor,TGF)-β诱导晶状体上皮细胞转分化、移行、过度增殖,是导致前囊膜下型白内障和后发性白内障发生的重要因素。CTGF与TGF—β主要通过Smad信号通路诱导晶状体上皮细胞发生转分化。CTGF是TGF—β的下游效应罔子,TGF—β调控CTGF的表达。
