Gut epithelial adhesion site

The "gut epithelial surface/pathogen adhesion sites" collectively refer to the anatomical and molecular features of the intestinal lining that provide initial contact points for microbes and pathogens. These include the mucus layer, brush border glycocalyx, cell-adhesion molecules (such as E-cadherin), and components of tight and adherens junctions. Together, these elements regulate the physical and biochemical barrier function of the gut, sense the microbial environment, modulate immune responses, and, in disease, can serve as entry points for pathogenic invasion[1][2][3][4]. Disruption or dysregulation of these sites is associated with increased susceptibility to infection and inflammatory disease.
