Abstract:
ObjectiveTo investigate the profile of Th17/Treg balance in the peripheral blood of patients with systemic lupus erythematosus (SLE).MethodsThirty-two SLE patients in active disease were selected and 30 SLE patients in remission were included in this study.The control group was consisted of 25healthy individuals.The expressions of IL-17 and FoxP3 on CD4+ T cells in the peripheral blood were assessed by flow cytometry and the mRNA levels of these two cytokines were examined by quantitative PCR respectively.ANOVA was used for statistical analysis.ResultsThe percentage of CD4+IL-17+ T cells and IL-17mRNA expression of the active group were significantly higher than those of the remission group and control group[(l.0l±0.22)％,(2.04±0.63)vs (0.48±0.16)％,(1.12±0.34) vs (0.41±0.12)％,1; P＜0.01].There was no difference between the remission group and control group(P＞0.05).However,the percentage of CI4+FoxP3 + T cells and FoxP3 mRNA expression of the active group were significantly lower than those of the remission group and control group [(2.36±t0.54)％,(0.42±0.16) vs (4.34±0.95)％,(0.87±t0.28) vs (5.09±11.17)％,1; P＜0.01 ],and there was also significant differencesbetween the remission group and control group(P＜0.05).ConclusionThl7/Treg balance shift may exist in the peripheral blood of patients with SLE and the degree of imbalance may be related to disease activity of SLE.
