波形蛋白与糖皮质激素性白内障的关系

长期全身或局部使用糖皮质激素可引起晶状体后囊下混浊( posterior subcapsular opacities, PSO),称为糖皮质激素性白内障( glucocorticoid-induced cataract, GIC )。有关GIC的发病机制,有多种假说,但都不能很好地解释PSO的形成过程,因而在预防和治疗上尚无有效手段。有新观点认为,激素可能通过其受体介导的波形蛋白的改变影响晶状体上皮细胞增殖和分化,最终导致GIC的形成。因此,研究波形蛋白对晶状体上皮细胞增殖和分化的影响,可能是GIC发病机制研究的一个新方向。

Relationship between vimentin and glucocorticoid-induced cataract

Long-term use of systemic or topical glucocorticoid can cause posterior subcapsular opacities(PSO), named glucocorticoid-induced cataract(GIC). There are many hypotheses on the pathogenesis of GIC. However, no one has well explained the formation of PSO, which leads to no effective approaches in the prevention and/or treatment. A new opinion is that hormones might affect lens epithelial cells through GR-mediated vimentin changes, which eventually result in the formation of GIC. Therefore, the association between vimentin and lens epithelial cell proliferation and differentiation, maybe a new direction for further studies in the pathogenesis of GIC.
