exocytosis

 [ek″so-si-to´sis]
1. the discharge from a cell of particles that are too large to diffuse through the wall; the opposite of endocytosis.
2. the aggregation of migrating leukocytes in the epidermis as part of the inflammatory response.

ex·o·cy·to·sis

(ek'sō-sī-to'sis),
1. The appearance of migrating inflammatory cells in the epidermis.
2. The process whereby secretory granules or droplets are released from a cell; the membrane around the granule fuses with the cell membrane, which ruptures, and the secretion is discharged. Synonym(s): emeiocytosis, emiocytosis Compare: endocytosis.

exocytosis

The movement of peptides or proteins out of a cell into the extracellular fluid, in tiny membranous vesicles that pass through the plasma membrane.
Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005

exocytosis

an active process in which vesicles containing excretory or secretory materials are actively carried to the periphery of the cell, and released to the outside when the vesicle membrane fuses with the cell membrane. Compare ENDOCYTOSIS. See PHAGOCYTOSIS, PINOCYTOSIS.

Complex carbohydrates occur in and on practically all cell types and in cellular secretions. They participate in a multitude of functions, such as fertilization, development and differentiation, cell sorting, motility, signal transduction and phagocytosis [1, 2].
In response to cellular secretions characteristic of inflammatory reactions, the number of ICAM-1 molecules on the surfaces of some mucosal cells increases many fold, to as many as 350 million per cell.
