子宫内膜异位症患者T辅助细胞亚群 殷红梅 王苏荣 戴淑真 王秋波 【摘要】 目的 探讨T辅助细胞(Th)失衡与子宫内膜异位症(内异症)的关系。
方法 对30例内异症患者(内异症组)及15例健康生育年龄妇女(对照组)的外周血单个核细胞(PBMC)加入植物血凝素进行体外培养诱生。采用酶联免疫吸附试验测定血浆及PBMC培养上清液中Th1类因子干扰素γ(IFN-γ)、Th2类因子白细胞介素4(IL-4)的水平。结果 (1)在PBMC诱生培养上清液中,内异症组IL-4的诱生水平[(32.8±12.5)ng/L]比对照组[(24.3±3.5)ng/L]明显升高(P<0.01),而IFN-γ的诱生水平内异症组[(1
095.6±375.6) ng/L]较对照组[(1 549.3±361.9)ng/L]下降,内异症组的IFN-γ/IL-4比值(37.7±17.5)下降,与对照组(71.1±12.1)比较,差异均有极显著性(P<0.01)。(2)在血浆中,除内异症组IL-4水平[(32.0±22.6)ng/L]高于与对照组[(23.3±4.3)ng/L](P<0.05)外,IFN-γ的诱生水平及IFN-γ/IL-4比值与对照组比较,差异均无显著性(P>0.05)。结论 内异症患者体内存在Th1/Th2失衡,使子宫内膜能够逃避免疫监视及杀伤而在异位种植,引起内异症的发生发展。 Study on Interferon γ and Interleukin-4 Contents of Plasma and Cultured Monoclear Cell Supernatants in Patients with Endometriosis YIN Hongmei, WANG Surong,

investigate the cytokin production of T helper cell (Th)1,Th2 subsets in patients with
endometriosis(EM). Methods The cytokine production of Th1,Th2 cells expressed by
interferon-γ (IFN-γ) and interleukin-4 (IL-4) contents respectively in supernatants of
cultured PHA induced peripheral blood mononuclear cell (PBMC) and plasma, obtained from 30
EM patients and 15 normal controls were determined by enzyme linked immunoabsorbent assay
(ELISA). Results IL-4 contents of EM patients were elevated both in plasma and PBMC
supernatants[(32.0±22.6) ng/L and (32.8±12.5) ng/L, respectively], while IFN-γ
levels was suppressed in PBMC supernatant as compared with normal controls [(1 095.6±375.6)
ng/L and (1 549.3±361.9) ng/L, respectively] (P<0.01,P<0.05).As a results, the
ratio of IFN-γ/IL-4 decreased in EM patients. Conclusions Changes of IFN-γ and IL-4
contents in EM patients may reflect functional inbalance between Th1 and Th2 cells, which
may play a role in the pathogenesis of EM. T辅助细胞(T helper cell,Th)根据其产生细胞因子的不同分为Th1和Th2两大亚群。正常状态下Th1、Th2处于动态平衡,一旦失衡则引起疾病。目前对子宫内膜异位症(内异症)患者Th亚群变化的研究结果尚不一致[1,2]。本研究对外周血单个核细胞(PBMC)加植物血凝素诱生培养,用酶联免疫吸附试验测定血浆及培养上清液中Th1类细胞因子干扰素(IFN)-γ、Th2类细胞因子白细胞介素4(IL-4)水平,研究内异症患者有无Th1、Th2失衡现象。 资料与方法 一、研究对象 结果 一、PBMC诱生培养上清液中IL-4、IFN-γ的水平及IFN-γ/IL-4比值变化 讨论 一、 Th1/Th2失衡在内异症中的意义 表1 两组患者IL-4、IFN-γ及IFN-γ/IL-4的水平( |
