Abstract:
AIM:To analyze the mechanism of tumor-associated macrophage (TAMs) in the development of cervical cancer and to investigate its correlation with Th1/Th2 and Th17/CD4+ CD25+ Foxp3 + Treg.METHODS:Twenty seven cases of cervical cancer and 53 cases of cervical intraepithelial neoplasias (including 22 cases of CIN Ⅱ and 31 cases of CIN Ⅲ) were selected as subjects.The venous blood of patients before treatment was extracted to detect Th1/Th2 and Th17/CD4 + CD25 + Foxp3 + Treg with flow cytometry,and detect serum IFN-γ,IL-4,IL-17A,IL-17F,TGF-β1 and IL-10 levels with ELISA Kits.Furthermore,pathological tissues were extracted during operation,and its TAMsCD68 expression was detected by immunohistochemistry technique.RESULTS:The Th1/Th2 and Th17/CD4 + CD25 + Foxp3 + Treg of cervical cancer were both lower than those of CIN Ⅲ,and those of CIN Ⅲ were both lower than CIN Ⅱ,the difference between groups had statistical significance (P ＜ 0.05).The serum IFN-γ,IL-4,IL-17A,IL-17F,TGF-β1 and IL-10 levels of cervical cancer were all higher than those of CIN Ⅲ,and those of CIN Ⅲ were all higher than CIN Ⅱ,the difference between groups had statistical significance (P ＜ 0.05).The TAMsCD68 expression level of cervical cancer was higher than that of CIN Ⅲ,and that of CIN Ⅲ was lower than CIN Ⅱ,the difference between groups had statistical significance (P ＜ 0.05).The correlation analysis results showed TAMsCD68 expression level had negative correlations with Th1/Th2,Th17/CD4+CD25+ Foxp3+ Treg,and serum IL-17A level,whereas presented positive correlations with serum IL-10 and IL-4 level (P ＜ 0.05).CONCLUSION:TAMs is closely related with Th1/Th2 and Th17/CD4 + CD25 + Foxp3 + Treg in cervical cancer,and possibly is mediating the occurrence and development of cervical cancer through influencing the balance of these two systems.
