【摘要】 目的从辅助性T细胞(Th)极化情况,探讨不同病程尖锐湿疣患者的细胞免疫状态。方法取肝素抗凝血,用密度梯度离心法分离出血浆和外周血单一核细胞(PBMC)进行细胞培养和免疫荧光染色:PHA和自身血浆刺激PBMC诱导T细胞极化,72h后收获细胞,分别标记抗CD4鄄PE与抗CCR5鄄FITC和抗CD4鄄FITC与抗CCR3鄄PE,最后利用流式细胞仪对标记细胞进行分析。结果尖锐湿疣患者中,短病程组与长病程组Th1/Th2极化细胞百分率分别为(25.82±2.22)%/(14.80±1.14)%与(12.20±1.37)%/(13.74±0.99)%,两组极化细胞百分率分别与正常对照组比较差异均有显著性(P <0.05),短病程组Th1/Th2的比值为1.75±0.17,而长病程组为0.89±0.11。结论短病程尖锐湿疣患者机体呈现Th1型反应,而长病程者则以Th2型反应为主,存在Th1型反应向Th2型反应切换的现象。更多还原

【Abstract】 Objective To investigate the status of cellular immunity from Th cell polarization in pa-tients with different courses of condyloma acuminatum(CA).Methods The isolated PBMC were polarized by PHA and self-plasma for72hours,then followed by two-color immunofluorescent staining with anti-CD4-PE and anti-CCR5-FITC,or with anti-CD4-FITC and anti-CCR3-PE.Finally the stained cells were analyzed by flow-cytometry.Results The percentages of Th1/Th2cells of the short-course group and long-course group were(25.82±2.22)%/(14.80±1.14)%and(12.20±1.37)%/(13.74±0.99)%,respectively;the differ-ences between normal control and two CA groups were significant(P<0.05).The Th1/Th2cells ratios of short-course and long-course group were1.75±0.17or0.89±0.11,respectively.Conclusions It seems that there was Th1predominant response in CA patients with short-course and Th2predominant response in long-course group.These data indicate that there may be an possible switch from Th1to Th2response in CA pa-tient with long-course.更多还原
