摘要：

Introduction: Allergic rhinitis (AR) is an IgE-mediated non-infectious disease of the nasal mucosa following contact with allergens. Objective: To investigate the peripheral Th17 cells and CD4 + CD25 + Foxp3 + regulatory T (Treg) cells and the expression of cytokines in the serum of AR patients. Methods: The peripheral blood of 14 patients with AR (AR group) and six healthy subjects (control group) was collected from March to May of 2012. Flow cytometry was performed to detect the Th17 cells and Treg cells, and enzyme-linked immunosorbent assay (ELISA) to measure the serum levels of IL-17 and TGF-β1. Results: The proportion of Th17 cells in the AR group was markedly higher than that in the control group (p < 0.01). The proportion of Treg cells in the AR group was also dramatically reduced when compared with the control group (p < 0.01). In the AR group, serum IL-17 levels were markedly higher than those in the control group (p < 0.01). In the AR group, serum TGF-β1 Levels were significantly lower than those in the control group (p < 0.01). Conclusion: The imbalance of peripheral Th17/Treg cells plays an important role in the pathogenesis of AR. (C) 2014 Associacao Brasileira de Otorrinolaringologia e Cirurgia Cervico-Facial.
