Moreover, the ER-mediated model shown cer-tainly does not represent our current view. WebMay 1, 2005 · Phagocytosis requires receptor-mediated recognition of particles, usually in the guise of infectious agents and apoptotic cells. Phagosomes fuse with lysosomes to generate phagolysosomes, which play a key role in enzymatic digestion of the internalized contents into component parts.
