Compensatory endocytosis in chromaffin cells
Acta Physiologica, 2007AbstractExocytosis occurs via fusion of secretory granules with the cell membrane, whereupon the granule content is at least partially released and the granule membrane is temporarily added to the plasma membrane. Exocytosis is balanced by compensatory endocytosis to achieve net equilibrium of the cell surface area and to recycle and redistribute ...

Anti-myosin stains chromaffin cells
Experientia, 1978The presence in fixed chromaffin cells of antigenic sites for a myosin antibody was demonstrated using immunofluorescence techniques. Tests on viable cells showed that at least some of the antigenic sites seem to be localized on or close to the cell surface and explained the cell agglutination that occurred with the addition of the myosin antibody to ...

Thiophosphorylated proteins in chromaffin cells are chromaffin vesicle matrix proteins
Neurochemistry International, 1992Bovine adrenal chromaffin cells were incubated with inorganic thiophosphate, using a protocol similar to experiments with inorganic phosphate, in order to determine the source of previously observed thiophosphoproteins. Incubation of cultured cells with [35S]thiophosphate resulted in its incorporation into cell constituents within 2 min.

1988
The term chromaffin cells is derived from the properties of the parenchymal cells of the adrenal medulla whereby they are stained from yellow to brown after treatment with chromate- or dichromate-containing fixatives (Bennett 1941; Wood 1963; Coupland 1965a). It was Kohn (1903) who named this phenomenon the chromaffin reaction.

Contractile Proteins in Chromaffin Cells
1983Publisher Summary Neurons and chromaffin cells share a common embryological origin, the neural crest. The adrenal chromaffin cell is a modified post-ganglionic sympathetic ganglion cell and releases its noradrenergic and adrenergic neurotransmitters into the blood stream, where they act as hormones.

Annals of the New York Academy of Sciences, 2002
Abstract: Exocytosis, stimulus‐secretion coupling, real‐time measurements of neurosecretion, and stimulus‐secretion‐synthesis coupling (stimulus‐transcription coupling) were all initially proposed and verified in the chromaffin cell. Detailed analysis of the molecules and pathways responsible for secretion and transsynaptic regulation of gene ...

The Chromaffin Cell and its Development
Neurochemical Research, 2005This article summarizes some of the recent progress in understanding the development of chromaffin cells. These cells are derivatives of the neural crest and are intimately associated with the sympathetic nervous system. Although a common sympathoadrenal (SA) progenitor cell for chromaffin cells and sympathetic neurons has been postulated, there is ...

Neurofilament Proteins in Cultured Chromaffin Cells
Journal of Neurochemistry, 1984Abstract: Antibodies were raised against the 200‐kd, 145‐kd, and 68‐kd subunits of a rat neurofilament preparation. Immunoblots showed that each antibody was specific for its antigen and that it did not cross‐react with any of the two other neurofilament polypeptides.

Catecholamine release from fractionated chromaffin cells
European Journal of Pharmacology, 1996Bovine chromaffin cells were separated by density gradient centrifugation into subfractions. After centrifugation on a self-generating Percoll gradient (42.75% isotonic Percoll, 30,000 x g for 22 min at 20 degrees C), the chromaffin cells were found in two clearly distinguishable peaks.

Biochemical studies on chromaffin cells
Naunyn-Schmiedebergs Archiv f�r Pharmakologie und Experimentelle Pathologie, 1967The past two decades have seen many advances in our knowledge of adrenergic mechanisms. Convergence of cytological and biochemical studies has greatly extended our knowledge and understanding of the chromaffin tissue. The stage is now set for a thorough study of the phenomenon of amine release.
