Hypoxia induces voltage-dependent Ca2+ entry and quantal dopamine secretion in carotid body glomus cells [Article]
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 [Article]
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 ...
