Phagocytosis

Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell In cell biology, phagocytosis (from Ancient Greek φαγεῖν (phagein), meaning 'to devour', κύτος, (kytos), meaning 'cell', and -osis, meaning 'process') is the process by which a cell - often a phagocyte or a protist - engulfs a large particle (≥ 0.5 μm) to form an internal compartment known as a phagosome : the engulfing and usually the destruction of particulate matter by phagocytes that serves as an important bodily defense mechanism against infection by microorganisms and. Toll-like receptors: Toll-like receptors, named after a similar receptor in fruit flies encoded by the Toll gene, bind to specific molecules produced by bacteria.Toll-like receptors are a key part of the innate immune system because, once bound to a bacterial pathogen, they recognize the specific bacteria and activate the immune response Phagocytosis Definition. Phagocytosis, or cell eating, is the process by which a cell engulfs a particle and digests it. The word phagocytosis comes from the Greek phago-, meaning devouring, and -cyte, meaning cell

Phagocytosis is the mechanism used by many protists (e.g. amoeba) to acquire nutrients.In humans and other multicellular animals, phagocytosis is an important defense mechanism against infection by microorganisms (e.g. bacteria) and the process of removing cell debris (e.g. dead tissue cells) and other foreign bodies Phagocytosis is a specific form of endocytosis by which cells internalise solid matter, including microbial pathogens.

Phagocytosis is a process by which cells ingest large particles (> 0.5 micrometers) into membrane-bound vesicles called phagosomes, which are then targeted to the lysosomes for enzymatic degradation Macrophages are scavenger cells that can ingest dead tissue and foreign cells. Macrophages form tentacles called pseudopods to surround an invader. Once inside the macrophage, the invader is walled of Overview The chemicals also attract white blood cells that eat microorganisms and dead or damaged cells. The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes

'During phagocytosis, monocytes, neutrophils and macrophages generate Superoxide radicals, hydrogen peroxide and the highly reactive hydroxyl radicals3.' 'In addition, these ligands markedly upregulated production of CD36, a scavenger receptor that regulates phagocytosis of apoptotic. Phagocytosis: The process by which a cell engulfs particles such as bacteria, other microorganisms, aged red blood cells, foreign matter, etc. The principal phagocytes include the neutrophils and monocytes (types of white blood cells). The prefix phago- comes from the Greek phago meaning to eat.

Phagocytosis. During phagocytosis, cells engulf large particles such as bacteria, cell debris, or even intact cells (Figure 12.34).Binding of the particle to receptors on the surface of the phagocytic cell triggers the extension of pseudopodia—an actin-based movement of the cell surface, discussed in Chapter 11 Phagocytosis Phagocytosis is a form of endocytosis. In the process of phagocytosis the cell changes shape by sending out projections which are called pseudpodia (false feet) Phagocytosis is the cellular process of engulfing solid particles by the cell membrane to form an internal phagosome, or food vacuole.
