The phagocytic cells of the immune system include macrophages, neutrophils, and dendritic cells. Phagocytosis of the hostsâ own cells is common as part of regular tissue development and maintenance.hese are immune cells that engulf, i.e. phagocytose, pathogens or particles. To engulf a particle or pathogen, a phagocyte extends portions of its plasma membrane, wrapping the membrane around the particle until it is enveloped (i.e. the particle is now inside the cell).
