Presence of early secretory antigenic target-6 (ESAT-6)-specific, interferon- gamma -secreting T cells in blood accurately marks tuberculosis infection. In tuberculous pleural effusions from 10 patients with tuberculosis, these cells were concentrated a mean of 15-fold (standard deviation, +/-6-fold), relative to their level in peripheral blood (P=.014), and displayed rapid effector function. Such cells were absent in 8 control patients with nontuberculous pleural disease. The recruitment of ESAT-6-specific T cells to inflamed tuberculous tissue demonstrates their function in vivo and suggests a novel way to diagnose tuberculous pleuritis.
血液中存在早期分泌性抗原靶标6(ESAT-6)特异性、分泌γ干扰素的T细胞可准确标记结核感染。在10例肺结核患者的结核性胸腔积液中,相对于外周血水平,这些细胞平均浓缩了15倍(标准差,±6倍)(P = 0.014),并表现出快速效应功能。8例非结核性胸膜疾病对照患者中不存在此类细胞。ESAT-6特异性T细胞向发炎的结核组织募集证明了它们在体内的功能,并提示了一种诊断结核性胸膜炎的新方法。
