DISCUSSION IBD is a chronic intestinal disorder typified by UC and CD[12]. rats were collected to measure mRNA and protein expression by PCR, Western blot and immunohistochemistry; serum levels of interleukin (IL)-10, transforming growth factor (TGF)-1 and IL-17A were detected by ELISA. RESULTS: The rats in the experiment group and model group experienced significantly more severe colitis than the ones in the control group (< 0.05) before treatment on day 0; no significant difference was observed between the experiment group and model group (> 0.05). After treatment with TY-51469, the rats in the experiment group had significantly less severe colitis compared with the model group on 7, 14, 21 and 28 d (< 0.05). The proportion of CD4+CD25+ Tregs was lower in the model group and experiment group than in the control group; the experiment group had a significantly higher proportion of CD4+CD25+ Tregs than that in the model group (< 0.05). The model group and experiment group demonstrated lower expression of Foxp3 than the control group; the experiment group had higher Foxp3 expression than the model group (< 0.05). Cytokines IL-10, TGF-1 and IL-17A were lower in the model group and experiment group than in the control group; the experiment group had higher expression than the model group (< 0.05). CONCLUSION: After treatment with chymase inhibitor TY-51469, the experiment group demonstrated more significantly reduced intestinal inflammation and higher expression of immune tolerance related cytokines (IL-10, TGF-1, IL-17A) and Foxp3 which is specifically expressed in Tregs compared with the model group. Therefore, chymase inhibitor TY-51469 might ameliorate the progression of DSS-induced colitis possibly by increasing the expression of Tregs and cytokines. values < 0.05 were considered statistically significant.
