To investigate the expression of peripheral blood gammadelta T cells/CD4 CD25+ regulatory T cells(Treg) and cytokines interleukin 17 (IL-17) and transforming growth factor beta1 (TGF-beta1) in patients with allergic rhinitis.
From March 2012 to July 2012, 32 patients with allergic rhinitis (AR group) and 20 healthy control subjects (control group) were collected. The expression of peripheral blood gammadelta T cells/Treg cells were measured by flow cytometry and the levels of IL-17 and TGF-beta1 were evaluated by ELISA. SPSS 16.0 software was used to analyze the data.
The percentages of gammadeltaT cells in AR group were (13.30 +/- 8.62)%, which was significantly higher (t = 5.18, P < 0.01) than those in control group (5.18 +/- 1.86)%. The percentages of Treg cells in AR group were (1.75 +/- 0.56)%, which were significantly lower (t = 7.46, P < 0. 01) than those in control group (4.76 +/- 1.74)%. The IL-17 levels in AR group were (668.55 +/- 45.15) pg/ml, which were also significantly higher (t = 8.97, P < 0.01) than those in control group (573.53 +/- 17.42) pg/ml. The TGF-beta1 levels in AR group were (0.34 +/- 0.04) pg/ml, which were also significantly lower (t = 9.51, P < 0.01) than those in control group (0.49 +/- 0.06) pg/ml. There was a negative correlation between the percentages of gammadelta T cells and Treg cells (r = -0.561, P < 0.01). There was a negative correlation between the percentages of gammadelta T cells and TGF-beta1 levels (r = -0.622, P < 0.01). A positive correlation was shown between the percentages of gammadelta T cells and IL-17 levels in AR (r = 0.469, P < 0.01). A positive correlation was shown between the percentages of Treg cells and TGF-beta1 levels in AR (r = 0.738, P < 0.01). There was no correlation between IL-17 levels and the percentages of Treg cells or TGF-beta1 levels (r value was -0.111, -0.196, all P > 0.05).
There are imbalances of gammadelta T and Treg cells in peripheral blood of patients with allergic rhinitis. gammadelta T cells may be the main cell to produce IL-17, which may play an important role in allergic rhinitis.
探讨变应性鼻炎患者外周血γδT细胞/CD4 CD25+调节性T细胞（Treg）及细胞因子白细胞介素17（IL-17）和转化生长因子β1（TGF-β1）的表达情况。
收集2012年3月至2012年7月期间32例变应性鼻炎患者（AR组）及20例健康对照者（对照组）。采用流式细胞术检测外周血γδT细胞/Treg细胞的表达，酶联免疫吸附测定法（ELISA）评估IL-17和TGF-β1水平。应用SPSS 16.0软件进行数据分析。
AR组γδT细胞百分比为（13.30±8.62）%，显著高于对照组（5.18±1.86）%（t = 5.18，P < 0.01）。AR组Treg细胞百分比为（1.75±0.56）%，显著低于对照组（4.76±1.74）%（t = 7.46，P < 0.01）。AR组IL-17水平为（668.55±45.15）pg/ml，也显著高于对照组（573.53±17.42）pg/ml（t = 8.97，P < 0.01）。AR组TGF-β1水平为（0.34±0.04）pg/ml，也显著低于对照组（0.49±0.06）pg/ml（t = 9.51，P < 0.01）。γδT细胞百分比与Treg细胞百分比呈负相关（r = -0.561，P < 0.01）。γδT细胞百分比与TGF-β1水平呈负相关（r = -0.622，P < 0.01）。AR组γδT细胞百分比与IL-17水平呈正相关（r = 0.469，P < 0.01）。AR组Treg细胞百分比与TGF-β1水平呈正相关（r = 0.738，P < 0.01）。IL-17水平与Treg细胞百分比或TGF-β1水平无相关性（r值分别为-0.111、-0.196，均P > 0.05）。
变应性鼻炎患者外周血γδT细胞和Treg细胞存在失衡。γδT细胞可能是产生IL-17的主要细胞，其在变应性鼻炎中可能起重要作用。
