Astragalus polysaccharide attenuates rat experimental colitis by inducing regulatory T cells in intestinal Peyer’s patches

Figure 5 Western blot analysis of IL-23, ROR-γt and STAT-5a expression. A: Representative Western blots of IL-23, ROR-γt, STAT-5 and GAPDH (n = 6); B: Quantitative analysis of ROR-γt protein (n = 6); C: Quantitative analysis of IL-23 protein (n = 6); D: Quantitative analysis of STAT-5a protein (n = 6). Data are mean ± SEM (n = 8). ^aP < 0.05, ^eP <0.000 vs normal group; ^cP < 0.05, ^bP < 0.01, ^fP < 0.001 vs TNBS group. TNBS: 2,4,6-trinitrobenzene sulfonic acid; APS: Astragalus polysaccharide; MES: Mesalazine.
