摘要: 青光眼是以视神经损伤和视野缺损为特征的不可逆致盲性眼病,其发病机制与小梁网和Schlemm管的结构和功能改变密切相关。整联素作为细胞膜表面的重要跨膜受体,是连接细胞外基质(extracellular matrix,ECM)和细胞骨架的重要桥梁。整联素在小梁网和Schlemm管中呈现不同的亚型分布并且通过调节细胞-ECM黏附、细胞骨架重组、细胞收缩力的表达与活性,影响小梁网组织的刚度和房水流出通路的形态结构与功能,预示靶向特定整联素亚型,尤其是αvβ3和β1亚基或有助于调控青光眼病理微环境。

Abstract: Glaucoma, an irreversible blinding eye disease characterized by optic nerve damage and visual field defects, has a pathogenesis closely linked to structural and functional alterations in the trabecular meshwork (TM) and Schlemm’s canal (SC). Integrins, serving as crucial transmembrane receptors on the cell surface, act as vital bridges connecting the extracellular matrix (ECM) to the cytoskeleton. Within the TM and SC, integrins exhibit subtype-specific distribution patterns. Through their modulation of cell-ECM adhesion, cytoskeletal reorganization, and cellular contractility, integrins critically influence TM tissue stiffness and the morphology/function of the aqueous humor outflow pathway. These roles suggest that targeting specific integrin subtypes—particularly αvβ3 and β1 subunits—may offer a promising strategy for modulating the pathological microenvironment in glaucoma.
