水通道蛋白(aquaporins，AQPs)主要介导自由水沿渗透压梯度被动跨生物膜转运，水通道蛋白在保持细胞内外环境的稳态平衡，完成生理功能方面发挥着重要的作用。晶状体纤维细胞中只表达三种水通道蛋白：AQP1、AQP0和AQP5，三种AQPs的不同功能及空间差异表达促进产生和调节微循环系统。AQPs相关基因的改变可导致白内障的发生。本文综述了近年来对AQP1、AQP0和AQP5研究，并讨论了其与先天性白内障发生的关系。

[Abstract]
Aquaporins(AQPs)mainly mediate passive transmembrane transport of free water along osmotic pressure gradient. Three aquaporins, AQP1, AQP0 and AQP5, expressed in lens fibroblasts. The different functions of AQPs play important roles in promoting the formation and regulation of microcirculatory system. Furthermore, mutations in AQP-related genes can lead to cataracts. This paper reviews the current research status of aquaporin, and discusses the relationship between aquaporin-related proteins and congenital cataract.
