Upon entering macrophages, most bacteria are enfolded into vesicles called phagosomes. (nyulangone.org)
EFF - 1 fusogen promotes phagosome sealing during cell process clearance in Caenorhabditis elegans (rockefeller.edu)
These processes appear to be regulated by circadian rhythms and response to environmental light, such that the number of phagosomes in the RPE is highest shortly after the onset of light. (jax.org)
