Neutralization of tumor necrosis factor alpha (TNF-alpha) significantly down-regulated antigen-induced lymphoproliferation and the expression of interleukin-12 p40 and gamma interferon mRNA and enhanced the viability of intracellular attenuated and virulent mycobacteria in cocultures of immune T cells and macrophages obtained from Mycobacterium bovis BCG-vaccinated guinea pigs. This suggests the crucial role of TNF-alpha in the activation of a type 1 T-cell response against Mycobacterium tuberculosis infection.
肿瘤坏死因子α(TNF-α)的中和作用显著下调了抗原诱导的淋巴细胞增殖以及白细胞介素-12 p40和γ干扰素mRNA的表达,并增强了从卡介苗接种的豚鼠获得的免疫T细胞和巨噬细胞共培养物中细胞内减毒和有毒力分枝杆菌的活力。这表明TNF-α在激活针对结核分枝杆菌感染的1型T细胞应答中起关键作用。
