Galectin-3 modulates T cell activity and is reduced in the inflamed intestinal epithelium in IBD

Abstract

Our results suggest that downregulation of epithelial galectin-3 in the inflamed mucosa reflects a normal immunological consequence, whereas under noninflammatory conditions, its constitutive expression may help to prevent inappropriate immune responses against commensal bacteria or food compounds. Therefore, galectin-3 may prove valuable for manipulating disease activity.
