SUSTAINED EXOCYTOSIS AFTER ACTION POTENTIAL-LIKE STIMULATION AT LOW FREQUENCIES IN MOUSE CHROMAFFIN CELLS DEPENDS ON A DYNAMIN-DEPENDENT FAST ENDOCYTOTIC PROCESS

SUSTAINED EXOCYTOSIS AFTER ACTION POTENTIAL-LIKE STIMULATION AT LOW FREQUENCIES IN MOUSE CHROMAFFIN CELLS DEPENDS ON A DYNAMIN-DEPENDENT FAST ENDOCYTOTIC PROCESS

Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable vesicles. However, the mechanism that allows such vesicle replenishment remains un...
