The anti-inflammatory and anti-fibrotic effects of D-CeO₂ in DSS-induced chronic colitis. A The scheme of animal experiments. B H&E staining, Masson staining, and C immunofluorescence were used to assess the levels of inflammation and fibrosis. D The MPO activity and relative mRNA levels of IL-1β, TNF-α, TGF-β, and α-SMA in colonic tissues. One-way of ANOVA were performed for statistical comparison, *p < 0.05, **p < 0.01, ***p < 0.001
