Abstract:
Objective To study the relationship between Treg cell numbers and level of TGF-β1,IL-10 in the immune microenvironment of rat liver cancer.Method 40 male Wistar rats were randomly divided into three groups,liver cancer model group (n =20),saline control group (n =10) and blank control group (n =10).Liver cancer model was established by intraperitoneal injection of DEN (100 mg/kg).Percentage of Treg cells in cancer tissues was detected by fiow cytometry and the expression level of TGF-β1 and IL-10 by immunohistochemical SABC.Results The ratio of Treg cells in CD4 + T cells was 14.32% ± 4.84% in liver cancer tissues,significantly higher than that in the blank control group 5.64% ±6.10% and the saline control group 7.95% ±3.55%.The difference was statistically significant (F =211.279,P < 0.05).The expression level of TGF-β1 and IL-10 in cancer tissues was significantly higher than the blank control group and the saline control group (FTGF-β1 =250.740,FIL-10 =152.744,all P <0.05).The number of Treg cells was positively correlated with TGF-β1,IL-10 level (P < 0.05).Conclusions TGF-β1,IL-10 and Treg cells significantly increased in rat experimental liver cancer tissues,and there was positive correlation between Treg cells,and TGF-β1 and IL-10 in liver cancer tissues.
