Diversity in Phagocytic Signaling -- Phagocytosis and Immunity -- Fc Receptor Phagocytosis -- Complement Receptors, Adhesion, and Phagocytosis -- Adding Complexity to Phagocytic Signaling: Phagocytosis-Associated Cell Responses and Phagocytic Efficiency -- Small GTP Binding Proteins and the Control of Phagocytic Uptake -- Regulation of Phagocytosis by Fc?RIIb and Phosphatases -- Phospholipases and Phagocytosis -- Calcium Signaling during Phagocytosis -- Phagosome Maturation.Although, Phagocytosis was first described nearly 120 year ago, we are just recently beginning to understand the molecules that phagocytic cells use to bring about this complex cell function. Molecular Mechanisms of Phagocytosis was prepared as a series of up-to-date essays (chapters) that describe the present knowledge on the various steps of the phagocytic process from initial cell contact, through internalization of the foreign particle, to the final phagosome formation where the phagocytosed particle is destroyed.
