摘 要: 【目的】 探讨慢性阻塞性肺疾病( COPD) 急性加重期、稳定期患者和肺功能正常吸烟者外周血中Th17 、Treg细胞的表达。【方法】 选取慢性阻塞性肺疾病急性加重患者28例、慢性阻塞性肺疾病稳定期患者22例、吸烟肺功能正常者(对照组)22例为研究对象。流式细胞术检测外周血中Th17细胞、CD4+CD25high Treg细胞的比例,ELISA 检测诱导痰IL-17、TGF-β1的水平。【结果】 急性加重期COPD组的外周血Th17比例(%)较稳定期COPD组增高(2.92 ± 0.16 vs 1.25±0.14,P < 0.001)、痰液IL-17水平(ng/L)较稳定期COPD组增高(82.33 ± 17.38 vs 12.64 ± 2.74,P < 0.001),外周血Treg比例(%)低于稳定期COPD组(8.52 ± 0.47 vs 11.45 ± 0.78,P < 0.001)。急性加重期COPD组、稳定期COPD组外周血中Th17比例与Treg比例均呈负相关(r分别为-0.723和-0.674,P均< 0.001)。【结论】 急性加重期COPD的气道局部和全身的免疫反应以促炎的“Th17反应”占优势,稳定期COPD以“Treg反应”占优势。
【Objective】 To investigate the expression of Th17 cells and Tregs in peripheral blood from the patients of stable chronic obstructive pulmonary disease (SCOPD) and chronic obstructive pulmonary disease (AECOPD). 【Methods】 28 patients of AECOPD, 22 outpatients of SCOPD and 22 smoking healthy donors were recruited. Th17 cells and CD4+CD25high Tregs were determined by flow cytometry. Concentrations of IL-17 and TGF-β in the sputum were detected by ELISA. 【Results】 Percentages of peripheral Th17 cells (2.92 ± 0.16%) in AECOPD were significantly higher than those in SCOPD (1.25 ± 0.14%, P < 0.001), Level of IL-17 in sputum (82.33 ± 17.38 ng/L) in AECOPD was significantly higher than those in SCOPD (12.64 ± 2.74 ng/L, P<0.001). Percentages of peripheral Treg cells (8.52 ± 0.47%) in AECOPD were significantly lower than those in SCOPD (11.45 ± 0.78%, P < 0.001). Remarkably negative correlations were seen between numbers of Th17 cells and Tregs in AECOPD (r = -0.723, P < 0.001) and SCOPD(r = -0.647,P < 0.001). 【Conclusions】 Th17 response was dominated in AECOPD whereas Treg response was dominated in SCOPD.
