Huangqin-Tang Ameliorates TNBS-Induced Colitis by Regulating Effector and Regulatory CD4⁺ T Cells

Figure 4

HQT regulates mRNA expression of Th1-, Th2-, Th17-, and Treg-related cytokines in the TNBS-induced colitis model. Rats with TNBS-induced colitis were treated with or without HQT (120 mg/kg). Total mRNA was extracted from colonic tissue to analyze the expression of Th1-related cytokines (a) IFN-γ and (b) IL-12; Th2-related cytokines (c) IL-4, (d) IL-13, and (e) IL-5; Th17-related cytokines (f) IL-17A and (g) IL-6; Treg-related cytokines (h) IL-10 by real-time polymerase chain reaction (PCR). Results represent the mean ± SD from eight mice per group. , versus the control group. ^Δ, ^ΔΔ versus TNBS-treated rats.
