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 ...

Figure 1: Diagram of a chromaffin cell, showing the relative distribution of secretory granules, mitochondria and endoplasmic reticulum (ER).

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 ...
