Macrophage-mediated bacterial clearance relies on phagocytic uptake of the pathogen, subsequent phagolysosomal maturation, and microbial degradation. In this issue of Cell Host & Microbe, Wong et al. (2017) report that a chloride transporter couples phagocytosis and bacterial clearance in an NF-κB-mediated feedforward loop, which is required for sustained pathogen uptake.
巨噬细胞介导的细菌清除依赖于病原体的吞噬作用、随后的吞噬体成熟和微生物降解。在本期《细胞宿主与微生物》中,Wong 等人(2017)报告称,氯离子转运蛋白通过 NF-κB 介导的正反馈环偶联吞噬作用和细菌清除,这是持续摄取病原体所必需的。
