Low Dose of Cyanidin-3-O-Glucoside Alleviated Dextran Sulfate Sodium–Induced Colitis, Mediated by CD169+ Macrophage Pathway

Abstract

The study is the first to demonstrate strong effects of C3G to alleviate DSS-induced colonic damage in mice. The effect of C3G on DSS-induced colitis clearly showed a decrease of CD169+ macrophages in both the colon and mLNs. An increase of CD169+ cells induced by type I IFN could be inhibited by C3G. All these data suggest that the role of C3G in colitic inflammation was mediated at least partially by CD169+ cells and the type I IFN pathway.
