Abstract

Compared with healthy tuberculin reactors, Mycobacterium tuberculosis-stimulated peripheral blood mononuclear cells from tuberculosis patients had diminished production and mRNA expression of the Th1 cytokines gamma interferon and interleukin 2 (IL-2), with no change in production and mRNA expression for the Th2 cytokines IL-4, IL-10, and IL-13. These results were confirmed by evaluation of T cells and CD4+ cells. At the level of systemic T cells, development of tuberculosis is associated with diminished Th1 but not enhanced Th2 responses.

摘要

与健康的结核菌素反应者相比,来自结核病患者的经结核分枝杆菌刺激的外周血单个核细胞产生的Th1细胞因子γ干扰素和白细胞介素2(IL-2)减少,且mRNA表达降低,而Th2细胞因子IL-4、IL-10和IL-13的产生及mRNA表达没有变化。通过对T细胞和CD4+细胞的评估证实了这些结果。在全身T细胞水平上,结核病的发生与Th1反应减弱有关,而非Th2反应增强。
