In this study, the percentage of M1 macrophage CD11b+F4/80+iNOS+ (Figure 5(e)) was significantly increased in DSS-induced colitis mice, and those of M2 macrophage CD11b+F4/80+CD206+ (Figure 5(f)) and CD11b+F4/80+CD163+ (Figure 5(g)) cells were significantly downregulated. This evidence concerns the gene ITGAM and colitis.
