CHROMAFFIN CELLS AS A SECRETORY SYSTEM: THE USE OF NEUROTOXINS

open access: closed, 2003
Both exocytosis of synaptic vesicles and secretory granules are controlled by cytoplasmic free Ca2+. The storage organelles fuse with the plasma membrane in response to a rise of the intracellular Ca2+ concentration, caused by an influx of Ca2+ from the extracellular space and/or release from intracellular stores.

Presence of cellular renin-angiotensin system in chromaffin cells of bovine adrenal medulla

open access: closedAmerican Journal of Physiology-Heart and Circulatory Physiology, 2002
The presence of a local renin-angiotensin system has been established in organs that serve as angiotensin targets. In this study, the expression of angiotensinogen mRNA and subcellular localization of renin, angiotensin-converting enzyme, and angiotensin II were investigated in bovine adrenal medullary cells in primary culture.

The chromaffin system of the beluga sturgeonHuso huso(Chondrostei): Histological, immunohistochemical and ultrastructural study

open access: closedItalian Journal of Zoology, 2004
Abstract The histology and fine structure of the chromaffin cells were examined in the beluga sturgeon Huso huso Linnaeus, 1758. Chromaffin cells, identified by the chromaffin reaction and immunohistochemical reactions for tyrosine hydroxylase, dopamine—s‐hydroxylase and phenylethanolamine‐N‐methyltransferase, were spread over the entire length of the ...

Hormone Secretion by Exocytosis with Emphasis on Information from the Chromaffin Cell System

open access: closed, 1985
Publisher Summary This chapter discusses hormone secretion by exocytosis with an emphasis on information from the chromaffin cell system. Exocytosis is the general mechanism by which many hormones, transmitters, enzymes, and other special proteins and peptides are secreted from cells.

Adrenal Grafts in the Central Nervous System: Chromaffin and Chromaffin Progenitor Cell Transplantation

2022
Chromaffin cells are neuroendocrine cells that synthesize and release catecholamines and neuroactive molecules. They have been used experimentally in animal models and preclinical studies as a source for cell replacement therapy in Parkinson's disease.
