Abstract:
Objective:To explore the expression of GITR/GITRL in rheumatoid arthritis(RA)and its correlation with clinical features of the disease.Methods:Fifty three RA patients,35 osteoarthritis(OA)patients and 35 healthy volunteers were included in the study.The real-time-fluorescence quantitative PCR method was used to analyze the expression level of GITR/GITRL mRNA.Using fluorescence-activated cell sorting(FACS),the expression of GITR on CD4+CD25+ T cells in peripheral blood monouuclear cells(PBMC)was detected.The levels of Anti-CCP antibody,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR)and rheumatoid factor(RF)of the RA patients were measured at the same time.Results:It was shown that the level of GITR/GITRL mRNA and the percentage of GITR+ T cells in the CD4+CD25+ T cell subpopulation[12.38?5.72/16.41?10.16,(28.12?16.85)%] were significantly higher than those of the OA group [9.59?5.87/12.09?7.53,(21.01?14.42)%,P
