Epithelial Barrier Integrity

Molecular classification: Cellular Structure, Physiological Barrier

Overview

Epithelial barrier integrity refers to the ability of epithelial cell layers to form a selective and protective barrier that separates internal tissues from external environments. This barrier is crucial for maintaining tissue homeostasis by regulating nutrient absorption, preventing pathogen invasion, and controlling immune responses. It is not a single molecule but rather an emergent property resulting from coordinated cellular structures (junctional proteins), secreted factors (mucins/antimicrobials), and dynamic interactions with local microbiota—all critical for health maintenance across multiple organ systems.
