21. Phagocytosis is followed by digestion of the ingested amoebae.22. Macrophages remove senescent erythrocytes, leukocytes, and megakaryocytes by phagocytosis and digestion. 23. Defensins will also improve the capacity of macrophage phagocytosis . 24. Symbionts are acquired via phagocytosis of bacteria by bacterioctyes. 25. Astrocytes and microglia cells digest the decaying organelles and dying neurons through phagocytosis . 26. However expression of this fragment in macrophages reduced phagocytosis . 27. Thus, filamentation leads to the prevention of phagocytosis and killing by predator. 28. Then they demonstrated that phagocytosis by retinal pigment epithelial cells induces gene expression. 29. Tunicate intelectin is an opsonin for phagocytosis by hemocyte. 30. The presence of phosphatidylserine then triggers phagocytosis to remove the dead or dying cell.
