phagocyte


phagocyte
A cell possessing the property of ingesting bacteria, foreign particles, and other cells. Phagocytes are divided into two general classes: 1) microphages, polymorphonuclear leukocytes that ingest chiefly bacteria; 2) macrophages, mononucleated cells (histiocytes and monocytes) that are largely scavengers, ingesting dead tissue and degenerated cells. SYN: carrier cell, scavenger cell. [phago- + G. kytos, cell]

phagocytic adj.

* * *

phago·cyte (faґgo-sīt) [phago- + -cyte] any cell capable of ingesting particulate matter, such as a microphage, macrophage, or monocyte. Such cells ingest microorganisms and other particulate antigens that are opsonized (coated with antibody or complement), a process mediated by specific cell-surface receptors (Fc receptors and complement receptors). Other cell types exhibit phagocytosis, but not specific phagocytosis of opsonized particles.
