AbstractRegulated exocytosis is a multistage process involving a merger between the vesicle and the plasma membrane, leading to the formation of a fusion pore, a channel, through which secretions are released from the vesicle to the cell exterior. A stimulus may influence the pore by either dilating it completely (full‐fusion exocytosis) or mediating a

The annexins are a group of homologous proteins that bind phospholipids in the presence of calcium. They may provide a major pathway for communication between cellular membranes and their cytoplasmic environment. Annexins have a characteristic "bivalent" activity in the sense that they can draw two membranes together when activated by calcium. This has

Neutrophils are short-lived, highly specialized phagocytes. Their main function is to defend the host organism against invading microbes. The properties required to perform this function are chemotactic responsiveness, mobility, and the ability to phagocytose. Microorganisms are sensed through the chemotactic signals they emit or induce; are approached

American Review of Respiratory Disease, 1991
Abstract Mucins produced by goblet cells of the respiratory mucosa are condensed while stored in secretory granules. Mucin condensation and its decondensation upon exocytosis can be explained by the theory of polymer gel phase transition. After the opening of a secretory pore, Ca2+ inside the granule is exchanged for extracellular Na+.

Publisher Summary This chapter elaborates a study analyzing mechanisms of exocytosis. Exocytosis is a method of discharge of secretory products in which there is selective release of granule-bound material. Other forms of secretion may cause nonselective release of cellular constituents.

AbstractCatecholamines and peptides secreted from dense‐core vesicles (DCVs) of adrenal chromaffin cells regulate a wide variety of physiological processes. For instance, the release of noradrenaline and adrenaline plays a key role in regulating heart rate and blood pressure.

The Molecules of Sperm Exocytosis
2016Exocytosis is a fundamental process used by eukaryotic cells to release biological compounds and to insert lipids and proteins in the plasma membrane. Specialized secretory cells undergo regulated exocytosis in response to physiological signals. Sperm exocytosis or acrosome reaction (AR) is essentially a regulated secretion with special characteristics.

Regulated exocytosis of neurotransmitter- and hormone-containing vesicles underpins neuronal and hormonal communication and relies on a well-orchestrated series of molecular interactions. This in part involves the upstream formation of a complex of SNAREs and associated proteins leading to the eventual fusion of the vesicle membrane with the plasma ...
