Gut mucosal barrier
A tolerance-oriented interface where mucus, epithelial continuity, microbes, and immune sentinels share one layered ecosystem.
Look for
- Villus surface and epithelial continuity
- Goblet-cell and mucus layer
- Microbial lumen above immune-rich tissue
Conceptual tissue cutaway, not histology. Villi, microbes, cells, and spacing are simplified and not to scale.
