Definition of phagocytosis in English:

phagocytosis

noun ˌfaɡə(ʊ)sʌɪˈtəʊsɪsˌfæɡəsaɪˈtoʊsəs

mass nounBiology

The ingestion of bacteria or other material by phagocytes and amoeboid protozoans.
〔生〕吞噬作用，噬菌作用
Example sentencesExamples
- During phagocytosis, monocytes, neutrophils and macrophages generate Superoxide radicals, hydrogen peroxide and the highly reactive hydroxyl radicals3.
- Fc receptors mediate various effects on immune cells, including proliferation of B cells and phagocytosis by phagocytes.
- In addition, these ligands markedly upregulated production of CD36, a scavenger receptor that regulates phagocytosis of apoptotic neutrophils.
- Destruction of the red cells occurs as a result of the red cell-bound autoantibodies to the Fc receptors on monocytes and macrophages; phagocytosis and cytotoxic lysis of the red cells subsequently occur.
- Weakened resistance to infection is caused by decreased antibody and complement production, leukocyte phagocytosis and intracellular killing, and macrophage phagocytosis.

Derivatives

phagocytize

verb ˈfaɡəsʌɪtʌɪzˈfæɡəsəˌtaɪz

[with object]

Biology

(of a phagocytic cell or amoeboid protozoan) ingest (bacteria or other material)
macrophages phagocytize bacteria in the wound
Example sentencesExamples
- In the case of the red blood cell, the useless heterochromatin is eventually ejected from the cell and phagocytized by macrophages.
- Although dendritic cells phagocytize apoptotic and necrotic cells to the same degree, only engulfment of necrotic cells induces dendritic cell maturation.
- The nodes contain macrophages, phagocytic cells that engulf (phagocytize) and destroy bacteria, dead tissue, and other foreign matter, removing them from the bloodstream.

phagocytose

verb ˈfaɡəsʌɪtəʊz

Biology

another term for phagocytize
In the resolving phase, the accumulated neutrophils undergo apoptosis and are subsequently phagocytosed by macrophages.
Example sentencesExamples
- However, eventually cells break into fragments, forming apoptotic bodies that are phagocytosed by macrophages or neighboring reticuloendothelial cells.
- The patient's platelets were phagocytosed by her own neutrophilic granulocytes.

Origin

Late 19th century: from phagocyte + -osis.
