[Porosome: a new organelle and the universal secretion machine in cells].

چکیده
A new cell organelle, porosome, discovered in the mid 1990's and its demonstration as the universal secretory machinery in cells is described. In contrast to the generally accepted belief that the secretory vesicle membrane is totally incorporated into the plasma membrane during cell secretion, it has been shown that secretory vesicles transiently dock and fuse with the porosome base via SNARE proteins to expel vesicular contents under intravesicular pressure which is generated by active transport of water through water channels located at the secretory vesicle membrane.

The story of cell secretion: events leading to the discovery of the 'porosome' - the universal secretory machinery in cells.
Cell secretion has come of age, and a century old quest has been elegantly solved. We have come a long way since earlier observations of what appeared to be 'fibrillar regions' at the cell plasma membrane, and electrophysiological studies suggesting the presence of 'fusion pores' at the cell plasma membrane where secretion occurs. Finally, the fusion pore or 'porosome' has been discovered, and ...
متن کاملThe sory of cell secretion: events leading to the dicovery of the ‘porosome’- the universal secretory machinery in cells
Secretion is a universal cellular process occurring in simple organisms such as bakers yeast to complex multicellular organisms including humans. Neurotransmission, digestion, immune response, or the release of hormones, each occurs as a result of cell secretion. Cell secretion involves the transport of vesicular products from within cells to the outside. For example, when we eat digestive enzy...
متن کاملFunctional organization of the porosome complex and associated structures facilitating cellular secretion.
Porosomes, the universal secretory machinery at the cell plasma membrane, are cup-shaped supramolecular lipoprotein structures, where membrane-bound vesicles transiently dock and fuse to release intravesicular contents during cell secretion. In this review, the discovery of the porosome and its structure, dynamics, composition, and functional reconstitution are outlined. Furthermore, the archit...

The release of neurotransmitters at the nerve terminal for neurotransmission, release of insulin from beta-cells of the endocrine pancreas for regulating blood glucose levels, the release of growth hormone from GH cells of the pituitary gland to regulate body growth, or the expulsion of zymogen from exocrine pancreas to digest food, are only a few examples of key physiological processes made po...

Secretion is a universal cellular process occurring in bakers yeast, to the complex multicellular organisms, to humans beings. Neurotransmission, digestion, immune response or the release of hormones occur as a result of cell secretion. Secretory defects result in numerous diseases and hence a molecular understanding of the process is critical. Cell secretion involves the transport of vesicular...
