Recent advances in chromaffin cell biology: Summing up the last International Symposium on Chromaffin Cell Biology
(Sociedad de Biología de Chile, 2004)
Chromaffin and sustentacular cells in the adrenal medulla of the viscacha (Lagostomus maximus maximus): A histochemical and immunohistochemical study
(Sociedad de Biología de Cuyo, 2017)
Chromaffin and sustentacular cells are common components of the adrenal medulla of mammalian species. However, subpopulations of these cells varies among the different species. While the rat adrenal medulla is known to ...
The immediately releasable pool of secretory vesicles in adrenal chromaffin cells
(Argentinean Physiological Society, 2013-01)
In neuroendocrine cells, such as adrenal chromaffin cells, the exocytosis of hormone-filled vesicles is triggered by a localized Ca2+ increase that develops after the activation of voltage-dependent Ca2+ channels. To reach ...
Blockade by NNC 55-0396, mibefradil, and nickel of calcium and exocytotic signals in chromaffin cells: Implications for the regulation of hypoxia-induced secretion at early life
(Elsevier B.V., 2015-03-15)
Adrenal chromaffin cells (CCs) express high voltage activated calcium channels (high-VACCs) of the L, N and PQ subtypes; in addition, T-Lype low-VACCs are also expressed during embryo and neonatal life. Effects of the more ...
How does the stimulus define exocytosis in adrenal chromaffin cells?
(Springer, 2018-01)
The extent and type of hormones and active peptides secreted by the chromaffin cells of the adrenal medulla have to be adjusted to physiological requirements. The chromaffin cell secretory activity is controlled by the ...
Chronic hypoxia upregulates adenosine 2a receptor expression in chromaffin cells via hypoxia inducible factor-2a: Role in modulating secretion
(2011)
Catecholamine (CAT) release from chromaffin tissue plays an essential role in the fetus which develops in a low O2 environment (hypoxia). To address molecular mechanisms regulating CAT secretion in low O2, we exposed a ...
Membrane cycling after the excess retrieval mode of rapid endocytosis in mouse chromaffin cells
(Wiley, 2013-03)
Aim: After exocytosis, neuroendocrine cells and neurones keep constant the plasma membrane and the releasable vesicle pools by performing endocytosis and vesicular cycling. Patch-clamp capacitance measurements on chromaffin ...
Age-dependent regulation of chromaffin cell proliferation by growth factors, dehydroepiandrosterone (DHEA), and DHEA sulfate
(National Academy of Sciences, 2007-12)
The adrenal gland comprises two endocrine tissues of distinct origin, the catecholamine-producing medulla and the steroid-producing cortex. The inner adrenocortical zone, which is in direct contact with the adrenomedullary ...
Blockade by agmatine of catecholamine release from chromaffin cells is unrelated to imidazoline receptors
(Elsevier B.V., 2001-04-06)
The blockade of exocytosis induced by the putative endogenous ligand for imidazoline receptors, agmatine, was studied by using on-line measurement of catecholamine release in bovine adrenal medullary chromaffin cells. ...
