Here we investigate the fate of single secretory vesicles after fusion with the plasma membrane by measuring capacitance changes and transmitter release in rat chromaffin cells using the cell ...

Serotonin is produced peripherally by the intestinal chromaffin cells and centrally by nuclei found in the lower pons and upper brain stem (Mills, 1997). It regulates emotional, personality ...

The 2004 WHO classification of endocrine tumors defines pheochromocytoma as a tumor arising from catecholamine-producing chromaffin cells in the adrenal medulla -- an intra-adrenal paraganglioma.
