ABSTRACT
Objective:
To investigate the correlation between the CTLA-4 expression in the peripheral blood CD4+ and CD8+T cells in the patients with glioma and glioma WHO classification and operation,and to clarify the clinical significances of CTLA-4.Methods:
60 patients with glioma from our hospital were selected as glioma group, and 46 healthy volunteers were used as control group.Then the CTLA-4 expression levels in the peripheral blood CD4+ and CD8+T cells of the subj ects in glioma group and control group were detected by fluorescence-activated cell sorting (FACS)and the relationship between CTLA-4 and glioma WHO classification and surgery was analyzed.Results:
The CTLA-4 expression levels in CD4+ and CD8+T cells in peripheral blood of the patients in glioma group were higher than those in control group (P<0.01).The CTLA-4 expression level in the patients with gradeⅣ glioma was the highest, the expression level of the patients with grade Ⅳ glioma was higher than that of the patients with grade Ⅲ glioma (P<0.01),and the expression level of grade Ⅲ the patients with was higher than that of the patients with grade Ⅱ (P<0.01).The expression level of CTLA 4 in CD4+ and CD8+T cells of the patients with glioma after operation was lower than before operation (P<0.01 ).Conclusion:
The CTLA-4 expression levels in the peripheral blood CD4+ and CD8+T cells are increased with the increasing of malignancy degree of the patients with glioma,and it has a promotion role in the occurrence of development of glioma.
