AbstractPhagocytosis is the process of recognition and engulfment of microorganisms or tissue debris that accumulate during infection, inflammation or wound repair. This ingestion, which is performed most efficiently by migrating, bone marrow‐derived cells called ‘professional phagocytes’, is essential for successful host defense.

Specialization in phagocytosis
Journal of Theoretical Biology, 1976Abstract When phagocytes have been incubated with a mixture of two types of particles (say A and B), a microscopic count can be made of cells having ingested i A-particles and j B-particles, for various i and j. Simple assumptions (the validity of which has been checked in a previous work) allow derivation of formulae that give a fair account of ...

Microbes and Infection, 2003
Phagocytosis is central to the microbicidal function of neutrophils. Pathogens are initially engulfed into a plasma membrane-derived vacuole, the phagosome, which proceeds to acquire degradative properties by a complex process termed maturation. In this chapter, we discuss the current knowledge of the molecular mechanisms underlying phagosome formation

CRC Critical Reviews in Toxicology, 1978
Primitive unicellular organisms depend greatly on internalization of particulate matter for nourishment. In metazoa, this process is further developed to play a major role in mechanisms of defense. This review analyzes, mainly in mammalian systems, the various phenomena surrounding the phagocytic act. Much of the emphasis is placed on experimental work

Australian Journal of Experimental Biology and Medical Science, 1968
SummaryTwo species of invertebrates, Parachaeraps bicarinatus, a freshwater crayfish, and Helix pomatia, a garden snail, were examined for the presence of cells which could phagocytose particulate material introduced into their vascular systems. By means of blood clearance studies and histological techniques, it was demonstrated that there existed a ...

Current Opinion in Immunology, 1996
Recent advances in research on phagocytosis include a better appreciation of the cross-talk between phagocytic receptors, the definition of multiple signaling domains within these receptors, and a deeper understanding of the downstream effector pathways leading to actin polymerization and particle internalization.

Endocrinology, 1955
AS HAS been pointed out by Thomas (1952, 1953), cortisone has been L demonstrated to reduce the resistance of mammals to bacteria, viruses, fungi, and bacterial toxins. In discussing the various methods whereby cortisone might act to produce these results, the author suggests the conclusion that the effect must be on the reticuloendothelial system (RES)

The Pharmacology of Phagocytosis
Rheumatology, 1978The biochemical mechanisms underlying the processes of chemotaxis, adhesion, phagocytosis and lysosomal enzyme secretion are described. Particular attention is drawn to the roles of aerobic glycolysis, the hexose monophosphate shunt, cyclic adenosine monophosphate, cyclic guanosine monophosphate and the microtubular and microfilament systems.

Phagocytosis and Related Phenomena
Protoplasma, 1967Phagocytosis in leukocytes has been shown to be accompanied by the stimulation of a number of metabolic functions. The process is dependent for the energy required on some of these changes, while others are simply concomitants of particle ingestion [1, 2, 3, 4].
