Background and aims To define the underlying cellular mechanisms of intestinal barrier dysfunction.Methods Rats were fed with 4% DSS to induce experimental colitis.We analyzed the sugars in 24h urine by HPLC, the expression of claudins, MBL and MBL-associated serine proteases 2 (MASP-2) in colonic mucosa by immunohistochemistry, and detected apoptotic cells in colonic epithelium by TUNEL.
