Core Tip

Core tip: When colitis was chemically induced with dextran sodium sulfate, 2 d after the end of the treatment, mice showed unequivocal sign of colitis, changes in the luminal environment of the large intestine, epithelial permeability loss, and dysbiosis. These inflammation-induced alterations progressively and partly resolved in the period of time following colitis induction. Early and long-term evaluation of the epithelial repairing process showed overlapping action of inflammatory and repairing markers, rather than successive actions.
