细胞壁成分的各向异性排列在细菌和真菌中普遍存在,但这种功能的各向异性如何影响微生物与宿主免疫细胞之间的相互作用尚不清楚。在这里,我们讨论了吞噬体成熟的问题,吞噬体成熟是宿主免疫细胞用来降解内化微生物的过程。我们开发了双面微颗粒作为模型病原体,它只在一个半球上显示配体,同时作为荧光传感器探测吞噬体降解过程中的生化反应。仅在一个半球上的荧光指示器使粒子传感器看起来像月亮一样。我们发现配体在颗粒上的各向异性呈现延迟了吞噬体中酸化和蛋白质水解的开始,但不影响它们的降解能力。我们的工作表明,在宿主-病原体相互作用期间,配体在病原体上的空间呈现在调节吞噬体的降解过程中起着关键作用。
Anisotropic arrangement of cell wall components is ubiquitous among bacteria and fungi, but how such functional anisotropy affects interactions between microbes and host immune cells is not known. Here we address this question with regard to phagosome maturation, the process used by host immune cells to degrade internalized microbes. We developed two-faced microparticles as model pathogens that display ligands on only one hemisphere and simultaneously function as fluorogenic sensors for probing biochemical reactions inside phagosomes during degradation. The fluorescent indicator on just one hemisphere gives the particle sensors a moon-like appearance. We show that anisotropic presentation of ligands on particles delays the start of acidification and proteolysis in phagosomes, but does not affect their degradative capacity. Our work suggests that the spatial presentation of ligands on pathogens plays a critical role in modulating the degradation process in phagosomes during host-pathogen interactions.
