Abstract

Bovine adrenal chromaffin cells were loaded with Na+ via either acetylcholine receptor-associated ion channels or voltage-sensitive Na+ channels. There were increases in [Ca2+]i, 45Ca2+ uptake and catecholamine secretion in both types of Na(+)-loaded cells relative to control cells in which Na+ loading had been prevented by hexamethonium and tetrodotoxin, respectively. These results show the presence of Na(+)-dependent Ca2+ influx activity in chromaffin cells which is probably mediated by the reverse mode of a Na+/Ca2+ exchanger.
