| 摘 要： | 目的 分析白介素23受体（interleukin 23 receptor，IL-23R）对结核感染中辅助型T细胞17（T helper cell 17，Th17）免疫应答的影响，探讨IL-23R在肺结核（tuberculosis，TB）发病机制中的作用。方法 选取2015年5~10月于北京胸科医院住院的21名活动性肺结核病人（active tuberculosis，ATB），2015年5~7月于北京昌平区结防所结核病体检的21名结核潜伏感染者（latent tuberculosis infection，LTBI）和21名健康对照（healthy donor，HD）为研究对象；分离外周血单个核细胞（peripheral blood mononuclear cell，PBMC），并做培养；检测PBMCs中IL-23R mRNA表达水平和PBMCs上清中IL-23和IL-17A水平；比较各组IL-23R mRNA表达水平，分析IL-23R表达水平对IL-17A水平的影响。结果 IL-23R mRNA表达水平:ATB组低于LTBI组（Z=-2.528，P=0.011），ATB组高于HD组（Z=-3.849，P<0.001）；IL-17A水平:ATB组低于LTBI组（t=2.238，P=0.031），ATB组高于HD组（t=4.733，P<0.001）；IL-23水平在三组中的差异无统计学意义（F=0.432，P=0.651）；在ATB患者中，IL-23R mRNA表达水平与IL-17A水平呈正相关（rs=0.438，P=0.047）。结论 结核分支杆菌感染中，IL-23R的表达水平对Th17细胞介导的免疫应答起到调节作用，可能影响到TB的易感性和感染转归。

| Abstract: | Objective To investigate the effect of interleukin 23 receptor (IL-23R) on T helper cell 17 (Th17) call-mediated immune response in mycobacterium tuberculosis (TB) infection,and to explore the role of IL-23R in the pathogenesis of pulmonary tuberculosis.Methods 21 active lung tuberculosis (ATB) patients were enrolled in Beijing chest hospital from July to October in 2015,21 cases of latent tuberculosis infection (LTBI) and 21 healthy Healthy Donors (HD) were selected from Beijing Changping center for tuberculosis control and prevention from May to July in 2015.The peripheral blood mononuclear cells (PBMCs) were isolated and cultured.The expression of IL-23R mRNA in PBMCs was detected,IL-23 and IL-17A levels in the supernatant of PBMCs were measured.The expression of IL-23R mRNA in different groups and the effect of IL-23R expression on IL-17A level were analyzed.Results The expression of IL-23R mRNA in ATB group was lower than that in LTBI group (Z =-2.528,P =0.011),and in ATB group was higher than that in HD group (Z =-3.849,P ＜ 0.001).The expression of IL-17A in ATB group was lower than that in LTB group (t =2.238,P =0.031),and ATB group was higher than that in HD group (t =4.733,P ＜ 0.001).There was no significant difference in IL-23 level between the three groups (F =0.432,P =0.651).IL-23R mRNA expression was positively correlated with IL-17A level (rs =0.438,P =0.047).Conclusions The expression level of IL-23R in mycobacterium tuberculosis infection can regulate the immune response mediated by Th17 cells,which may affect the susceptibility and infection outcome of pulmonary tuberculosis. |
