摘要
目的检测白细胞介素(IL)-17+CD4+T(Th17)细胞和IL-17+CD8+T(Tc17)细胞在肺癌患者外周血中的表达水平,探讨二者在肺癌免疫中的作用及临床意义。方法采用流式细胞术(FCM)检测60例肺癌患者及40例健康对照者外周血中Th17和Tc17细胞占CD3+T细胞的比例。结果肺癌组外周血中Th17细胞[(1.795±0.623)%]和Tc17细胞[(0.865±0.357)%]比例分别高于对照组[(1.405±0.256)%、(0.640±0.204)%],(t=28.944,P<0.001;t=14.051,P<0.001)。两组内Th17细胞与Tc17细胞的表达水平均呈正相关(肺癌组r=0.770,P<0.05;对照组r=0.532,P<0.05)。Th17细胞和Tc17细胞表达均与临床分期有关(F值分别为4.882、3.633,均P<0.05),但与病理类型无关(均P>0.05)。结论肺癌患者体内Th17细胞和Tc17细胞表达升高,二者可能参与了肺癌的发生、发展;Th17与Tc17细胞的表达水平可作为评价肺癌患者免疫功能状态的新指标,能为病情监测提供参考。
