Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells
(Wiley-Blackwell Publishing Ltd., 2003)
Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes ...

Trophic restoration of the nigrostriatal dopaminergic pathway in long-term carotid body-grafted parkinsonian rats
(2003)
We studied the mechanisms underlying long-term functional recovery of hemiparkinsonian rats grafted intrastriatally with carotid body (CB) cell aggregates. Amelioration of their motor syndrome is a result of the trophic ...

Collapse of conductance Is prevented by a Glutamate residue conserved in voltage-dependent K+ channels
(2000)
Voltage-dependent K 1 channel gating is influenced by the permeating ions. Extracellular K 1 determines the occupation of sites in the channels where the cation interferes with the motion of the gates. When external [K 1] ...

Secretory responses of intact glomus cells in thin slices of rat carotid body to hypoxia and tetraethylammonium
(2000)
We have developed a thin-slice preparation of whole rat carotid body that allows us to perform patch-clamp recording of membrane ionic currents and to monitor catecholamine secretion by amperometry in single glomus cells ...
