现代结核分枝杆菌北京亚系的高流行率可能与增强的毒力有关,尽管其机制尚不清楚。我们先前描述了现代北京菌株中三酰甘油积累的增强。在这里,我们表明现代北京菌株在体外生长更快,并引发强烈的免疫反应和明显的巨噬细胞浸润。对现代北京系感染的骨髓源性巨噬细胞的转录组学分析显示,感染、胆固醇稳态和氨基酸代谢途径显著富集。通过RT-PCR分析证实了促炎/杀菌细胞因子的上调,这也与现代菌株感染巨噬细胞后细菌负担减轻一致。这些结果表明,现代北京菌株引起高炎症反应,这可能表明更强的毒力,并有助于其广泛的全球流行。
The high prevalence of the modern Beijing sublineage of Mycobacterium tuberculosis may be related to increased virulence, although the responsible mechanisms remain poorly understood. We previously described enhanced triacylglycerol accumulation in modern Beijing strains. Here we show that modern Beijing strains grow faster in vitro and trigger a vigorous immune response and pronounced macrophage infiltration. Transcriptomic analysis of bone marrow derived macrophages infected with modern Beijing lineage strains revealed a significant enrichment of infection, cholesterol homeostasis and amino acid metabolic pathways. The upregulation of proinflammatory / bactericidal cytokines was confirmed by RT–PCR analysis, which is also in consistent with the reduced bacterial burden in modern strains infected macrophages. These results suggest that modern Beijing strains elicit a hyperinflammatory response which might indicate a stronger virulence and contribute to their extensive global prevalence.
