The aim of this study was to explore the relationships between TregFoxP3(+) cells and Th17 cells and occurrence of lung cancer.
The proportions of TregFoxP3(+) and Th17 cells, the expression of FoxP3 and RORγt mRNA, and the levels of related cell factors such as transforming growth factor-β (TGF-β), interleukin IL-17 (IL-17) and IL-23 were determined respectively by flow cytometry analysis, real-time-polymerase chain reaction (PCR), and ELISA in peripheral blood of 18 healthy people and 26 patients with non-small cell lung cancer (NSCLC).
The levels of TregFoxP3(+) and Th17, expression of FoxP3 and RORγt mRNA, and ratios of TregFoxP3(+)/Th17 and FoxP3/RORγt in peripheral blood with NSCLC were higher than those in healthy controls (p < 0.05). The proportion of Th17 cells from NSCLC patients was positively correlated with that of TregFoxP3(+) (r = 0.81, p < 0.05). The receiver-operating characteristic (ROC) curve demonstrates that the increased level of TregFoxP3(+)/Th17 in the peripheral blood may be a useful indicator in early diagnosis of non-small cell lung carcinoma. The TregFoxP3(+)/Th17 and FoxP3/RORγt levels for patients in stage IV were higher than those of patients in stages I, II, and III (p < 0.05). The levels of TGF-β, IL-17, and IL-23 were higher in NSCLC patients than those in healthy controls.
The results suggest that ratios of Treg/Th17 correlate with the stage of NSCLC.
本研究旨在探讨调节性 T 细胞 FoxP3(+)细胞与 Th17 细胞与肺癌发生的关系。
采用流式细胞术分析、实时聚合酶链反应（PCR）和酶联免疫吸附试验（ELISA）分别检测外周血中 18 名健康人和 26 名非小细胞肺癌（NSCLC）患者的 TregFoxP3(+)和 Th17 细胞比例、FoxP3 和 RORγt mRNA 表达以及转化生长因子-β（TGF-β）、白细胞介素-17（IL-17）和白细胞介素-23（IL-23）等相关细胞因子水平。
肺癌患者外周血 TregFoxP3(+)和 Th17 细胞水平、FoxP3 和 RORγt mRNA 表达及 TregFoxP3(+)/Th17 和 FoxP3/RORγt 比值均高于健康对照组（p<0.05）。肺癌患者 Th17 细胞比例与 TregFoxP3(+)呈正相关（r=0.81，p<0.05）。受试者工作特征（ROC）曲线表明，外周血 TregFoxP3(+)/Th17 水平升高可能是早期诊断非小细胞肺癌的有用指标。IV 期患者 TregFoxP3(+)/Th17 和 FoxP3/RORγt 水平高于 I、II、III 期患者（p<0.05）。肺癌患者 TGF-β、IL-17 和 IL-23 水平高于健康对照组。
结果表明 Treg/Th17 比值与 NSCLC 分期相关。
