| Abstract: | Objective:To explore the expression and distribution pattern of Foxp3+Treg and IDO protein in cervical carcinoma and its precancerous lesions.Methods:Western blot and immunocytochemistry(ICC)were conducted to investigate the expression of Foxp3 protein and IDO protein in three cervical cancer cell lines-HeLa,SiHa and C33A.Immunohistochemistry(IHC)was used to investigate their expression patterns in 45 cases of cervical lesions tissues of the cervix and 20 cases of normal cervix tissues.Results:Foxp3 protein was not expressed in HeLa,SiHA and C33A.IDO protein was expressed in the cytoplasm of HeLa,Siha and C33A cells,Foxp3 protein was expressed in cervical tissue and Treg protein,IDO protein was expressed in APC and abnormal cells in cervical tissue.Compared with normal cervix,the expression of Foxp3+Treg(H=43.211,P=0.000)and IDO protein(χ2=20.028,P=0.00;Z=226.600,P=0.00)were significantly increased in cervical lesions.Compared with low grade squamous cell carcinoma,the invasion of Foxp3+Treg was increased in high grade squamous cell carcinoma(H=28.307,P=0.000).The results of Foxp3+Treg investigation in different cervical lesions showed that Foxp3+Treg expression was positively correlated with IDO protein(rs=0.550,P=0.000).Conclusion:In cervical immune microenvironment,Foxp3+Treg and IDO protein which expressin the APC and abnormal differentiated cell may synergistically promote immunosuppression status,which plays an important role in the occurrence and development of tumor microenvironment milieu,especially in low grade cervical lesions. |
