Rab3D Is Not Required for Exocrine Exocytosis but for Maintenance of Normally Sized Secretory Granules
(2002)
Rab3D, a member of the Rab3 subfamily of the Rab/ypt GTPases, is expressed on zymogen granules in the pancreas as well as on secretory vesicles in mast cells and in the parotid gland. To shed light on the function of Rab3D, ...

Hypoxia induces voltage-dependent Ca2+ entry and quantal dopamine secretion in carotid body glomus cells
(1994)
We have investigated the changes of cytosolic [Ca2+1 and the secretory -activity in single glomus cells dispersed from rabbit carotid bodies during exposure to solutions with variable 02 tension (Po2). In normoxic conditions ...

Oxygen sensing by ion channels and chemotransduction in single glomus cells
(1996)
We have monitored cytosolic [Ca2+] and dopamine release in intact fura-2-loaded glomus cells with microfluoroimetry and a polarized carbon fiber electrode. Exposure to low PO2 produced a rise of cytosolic [Ca2+] with two ...

Monitoring synaptic function at the neuromuscular junction of a mouse expressing synaptopHluorin
(2007)
We monitored presynaptic exocytosis and vesicle recycling at neuromuscular junctions of transgenic mice expressing synaptopHluorin (spH), using simultaneous optical and electrophysiological recordings. Synaptic transmission ...
