鼠伤寒沙门氏菌通过在宿主巨噬细胞中复制建立全身感染。在这里,我们表明,巨噬细胞感染的S。鼠伤寒沙门氏菌表现出糖酵解上调和丝氨酸合成减少,导致糖酵解中间体积累。对丝氨酸合成的影响由细菌蛋白SopE 2介导,SopE 2是致病岛SPI-1中编码的III型分泌系统(T3 SS)效应子。宿主代谢的改变促进了S.鼠伤寒沙门氏菌通过两种机制:葡萄糖水平的降低导致细菌对2-和3-磷酸甘油酸和磷酸烯醇丙酮酸(碳源)的摄取上调,而丙酮酸和乳酸水平的增加诱导另一种致病岛SPI-2的上调,已知SPI-2编码毒力因子。宿主糖酵解的药理学或遗传学抑制、宿主丝氨酸合成的激活或这些宿主糖酵解中间体的细菌转运或信号传感器系统的缺失损害S。鼠伤寒复制或毒力。
Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on serine synthesis are mediated by bacterial protein SopE2, a type III secretion system (T3SS) effector encoded in pathogenicity island SPI-1. The changes in host metabolism promote intracellular replication of S. Typhimurium via two mechanisms: decreased glucose levels lead to upregulated bacterial uptake of 2-and 3-phosphoglycerate and phosphoenolpyruvate (carbon sources), while increased pyruvate and lactate levels induce upregulation of another pathogenicity island, SPI-2, known to encode virulence factors. Pharmacological or genetic inhibition of host glycolysis, activation of host serine synthesis, or deletion of either the bacterial transport or signal sensor systems for those host glycolytic intermediates impairs S. Typhimurium replication or virulence.
