Gastrointestinal Mucus Barrier (GIMB)

Target
GIMB
Molecular classification
Extracellular matrix component, Glycoprotein complex, Physical barrier
01

Overview

The gastrointestinal mucus barrier is an essential protective interface formed mainly by secreted mucin glycoproteins from goblet cells. It maintains intestinal homeostasis by physically separating luminal threats from host tissues while supporting digestion and selective permeability. Its disruption contributes significantly to gastrointestinal pathology including chronic inflammation and infection risk.
