Curcumin improves regulatory T cells in gut-associated lymphoid tissue of colitis mice

Figure 3 Concentrations of cytokines in the colonic mucosa. The tissue supernatant was prepared from the colonic mucosa in all mice. The levels of cytokines were analyzed by ELISA. A: Concentrations of TNF-α in the colonic mucosa from different groups; B: Concentrations of IL-2 in the colonic mucosa from different groups; C: Concentrations of IL-6 in the colonic mucosa from different groups; D: Concentrations of IL-12 p40 in the colonic mucosa from different groups; E: Concentrations of IL-17 in the colonic mucosa from different groups; F: Concentrations of IL-21 in the colonic mucosa from different groups. Data are expressed as mean ± SE (n = 8). ^aP < 0.05 and ^bP < 0.01 vs normal group; ^cP < 0.05 and ^dP < 0.01 vs TNBS group.
