Ocular Surface Epithelial Cell Hydration (OSE Hydration)
- Target
- OSE Hydration
- Molecular classification
- Physiological Process, Homeostasis
01
Overview
Ocular surface epithelial cell hydration is the physiological process that maintains the water content and wettability of the corneal and conjunctival epithelial cells. This process relies on mucins (secreted and transmembrane), which create a hydrophilic environment that retains the tear film, provides lubrication, and protects the ocular surface. Disruption of this process leads to dry eye disease and other ocular surface disorders.

02
Mechanism of action
Maintenance of a hydrated microenvironment on the ocular surface through a combination of secreted and transmembrane mucins, which attract and retain water via hydrophilic O-glycans.
03
Biological functions
Maintenance of corneal transparencyLubrication of ocular surfaceProtection against environmental stressorsTear film stabilityBarrier function against pathogens
