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.
