The Expression of IL-27, Th17 Cells and Treg Cells in Peripheral Blood of Patients with Allergic Rhinitis

摘要

Objective: To explore the expression of IL-27, Th17 cells and CD4+CD25+ regulatory T cells (Treg) as well as its associated cytokines in peripheral blood of patients with allergic rhinitis (AR). Method: From March 2012 to May, the peripheral blood of 24 cases of AR patients (AR group) and 16 cases of healthy volunteers (control group) was collected, and the percentage of Th17 cells and Treg cells in the peripheral blood was detected by flow cytometry (FCM); the levels of IL-27, IL-17 and IL-10 in serum was detected by ELISA. Result: The percentage of Th17 cells in AR group and the control group was 1.76% ± 0.60% and 0.59% ± 0.17%, respectively. It was higher in AR group than in control group, and the difference between two groups was statistically significant (P 0.05). Conclusion: In the peripheral blood of AR patients there was a reduction of IL-27 level and imbalance of Th17/Treg cell function. IL-27 on Th17/Treg cells adjustment may play an important role on the pathogenesis of the AR.
