Elemental Diet Enriched with Amino Acids Alleviates Mucosal Inflammatory Response and Prevents Colonic Epithelial Barrier Dysfunction in Mice with DSS-Induced Chronic Colitis

Figure 5

An elemental diet enriched in amino acids prevents colonic epithelial barrier dysfunction induced by dextran sulfate sodium (DSS), maintaining the expression of tight junction proteins. Immunofluorescence staining of claudin-1, occludin, and ZO-1 in the intestinal tissues from different groups of mice with positive expression (green) determined by confocal microscopy. Cell nuclei were stained with DAPI (blue). Scale bar, 100 μm.
