    摘要:

    瞬时受体电位香草醛受体4(TRPV4)是一种非选择性阳离子通道,负责感知细胞肿胀、温度、机械牵张、剪切应力和渗透压的变化,通过调节跨膜钙信号进而影响基因表达、细胞形态和细胞骨架等构建。TRPV4在全身各器官组织中广泛表达。在眼部,TRPV4在角膜、晶状体、睫状体、小梁网和视网膜等组织均有功能性表达。本文就TRPV4在眼内各个组织中的表达及其生理病理功能方面进行阐述。随着TRPV4在眼部病理生理功能中的深入研究,TRPV4在角膜损伤修复、调节晶状体光学特性、青光眼控制眼压及视网膜血管生成方面可能成为潜在的新兴药物靶点,但仍需进一步的深入研究。

    Abstract:

    Transient receptor potential vanilloid receptor 4 ( TRPV4 ) is a non-selective cation channel responsible for sensing changes in cell swelling, temperature, mechanical stretch, shear stress and osmotic pressure by regulating transmembrane calcium signaling and thereby influencing gene expression, cell morphology, and cytoskeletal construction. TRPV4 is widely expressed in various organs and tissues throughout the body. In the eyes, TRPV4 is functionally expressed in the cornea, lens, ciliary body, trabecular meshwork and retina. In this article, we described the expression and physiopathological functions of TRPV4 in various tissues of the eye. With the in-depth study of TRPV4 in ocular pathophysiological functions, TRPV4 may become a potential drug target in corneal injury repair, adjustment of the optical properties of the lens, controling intraocular pressure and retinal angiogenesis, but further in-depth study is still needed.
