Ocular surface epithelial cell membranes

The ocular surface epithelial cell membranes, encompassing the corneal and conjunctival epithelia, serve as the primary interface between the eye and the external environment. These membranes are characterized by a complex glycocalyx composed of membrane-associated mucins (MUC1, MUC4, MUC16) that maintain hydration and provide a barrier against pathogens and mechanical stress [1][2]. Beyond their structural role, these membranes house various receptors, ion channels, and adhesion molecules that regulate cellular signaling and inflammatory responses [3]. In conditions such as dry eye disease or chronic inflammation, the integrity of these membranes is often compromised, leading to increased permeability and cellular damage [4]. Therapeutic interventions often target specific components within these membranes, such as integrins or mucin secretagogues, to restore the ocular surface's protective barrier and reduce inflammatory signaling [5]. Consequently, these membranes are central to the pathophysiology of ocular surface diseases and represent a key focus for drug delivery and therapeutic stabilization [6].
