WebbPhagocytosis is a universal cell function, which starts with the recognition and binding of a particle (over 0.5 µm in diameter), generally in a receptor-dependent manner, and leads to its internalization and degradation. Single-celled eukaryotes such as the mold Dictyostelium discoideum and amoebae use phagocytosis for feeding.

Eight lectin-like domains form the extracellular part of the receptor. The ingestion mediated by the mannose receptor is distinct in molecular mechanisms from Fcγ receptor or complement receptor mediated phagocytosis. Phagosome. Engulfment of material is facilitated by the actin-myosin contractile system. Visa mer Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat', and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the Visa mer Phagocytosis was first noted by Canadian physician William Osler (1876), and later studied and named by Élie Metchnikoff (1880, 1883).
