Piezo1是一种多重跨膜蛋白,属于机械敏感性非选择性阳离子通道,能够响应细胞膜上的机械力刺激,在多种生理和病理过程中发挥重要作用。近年来,研究发现Piezo1与眼科疾病的发生和发展密切相关。Piezo1通过调控细胞增殖、分化、凋亡和炎症反应等过程参与眼科疾病的发生发展,尤其是在青光眼、角膜疾病、视网膜疾病和干眼等方面。Piezo1在眼科领域的研究进展迅速,它被确立为眼内重要的机械传感器,广泛参与眼内压调节、视网膜功能维持、角膜稳态与修复、以及眼发育等关键过程,其功能异常与多种重要致盲性眼病的病理机制密切相关。因此,Piezo1不仅是理解眼部机械生物学的重要分子,更是一个极具潜力的新型治疗靶点,为未来开发针对这些眼病的新疗法带来了希望。文章总结了近年来Piezo1离子通道在眼科疾病中的研究进展,探讨其作用机制和潜在的治疗价值,为眼科疾病的诊断和治疗提供新的思路。

[Abstract]
Piezo1, a mechanosensitive nonselective cation channel characterized by multiple transmembrane domains, plays a critical role intransducing mechanical stimuli at the cellular membrane and participates in various physiological and pathological processes. Recent studies have established a significant association between Piezo1 and the occurrence and development of multiple ophthalmic disorders. Substantial evidence demonstrates that Piezo1 contributes to ocular disease progression by regulating fundamental cellular processes including proliferation, differentiation, apoptosis, and inflammatory responses, with particular relevance to glaucoma, corneal diseases, retinal disorders, and dry eye syndrome. Piezo1 has made rapid progress in ophthalmology, and has been established as an important mechanosensor in the eye, widely involved in intraocular pressure regulation, retinal function maintenance, corneal homeostasis and repair, and ocular development, and its dysfunction is closely related to the pathological mechanisms of many important blinding eye diseases. Consequently, Piezo1 is not only a key molecule for understanding ocular mechanobiology, but also represents a highly promising therapeutic target. Its study offers new perspectives for the development of novel therapeutic strategies against ocular diseases. This review systematically summarizes current research advances regarding Piezo1 channels in ophthalmology, analyzes their mechanistic involvement in disease processes, and evaluates their potential therapeutic value, thereby offering innovative perspectives for the clinical management of ocular diseases.
