Epithelial Cell Barrier Function in Viral Entry
- Molecular classification
- Cell-cell junction, Physical barrier, Epithelial cell structure
01
Overview
The epithelial cell barrier, formed by tight junctions, adherens junctions, and desmosomes, prevents viral entry and systemic spread. Viruses employ strategies to disrupt these junctions, expose hidden receptors, or utilize transcytosis/endocytosis to breach this barrier. Maintaining the integrity of the epithelial barrier is crucial for preventing infections and inflammatory diseases.
