endocytosis

 [en″do-si-to´sis]
the uptake by a cell of material from the environment by invagination of the plasma membrane; it includes both phagocytosis and pinocytosis.
Endocytosis. Shown are pinocytosis of small fluid droplets (left) and phagocytosis of a large particle (right). From Dorland's, 2000.

en·do·cy·to·sis

(en'dō-sī-tō'sis),
Internalization of substances from the extracellular environment through the formation of vesicles formed from the plasma membrane. There are two forms: (a) fluid phase (pinocytosis), and (b) receptor mediated.
See also: phagocytosis. Compare: exocytosis (2).

A process of cellular ingestion by which the plasma membrane folds inward to bring substances into the cell.

endocytosis

A method by which a large molecule, such as a protein, can enter a cell. The plasma membrane of the cell is invaginated by the molecule so that an internal vesicle is formed containing the molecule. This then breaks off from the surface membrane and moves into the interior of the cell. Such vesicles are coated with a protein called clathrin.

endocytosis

an active process by which some cells can enclose a smaller body (e.g. a food particle) forming a membrane-bound vesicle. Compare EXOCYTOSIS. See PHAGOCYTOSIS, PINOCYTOSIS.

receptor mediated endocytosis
uptake of materials bound to specific cell-surface receptors by invagination of the plasma membrane to form a small membrane-bounded vesicle; a mechanism for entry of viruses into cells.

ROS also damage cytoskeletal proteins, leading to a probable loss in defense function, because hemocyte adhesion, motility, endocytic ability and the capacity to phagocytose foreign particles all depend on the cytoskeleton (Bellomo & Mirabelli 1992).
