In this study the effect of the A1 agonist 2-chloro-N6-cyclopentyladenosine (CCPA) on bis(1,3-diethylthiobarbituric acid)trimethine oxonol (bisoxonol)-monitored membrane potential in cerebrocortical nerve endings was evaluated. CCPA (30, 100 and 300 microM) caused a dose-dependent decrease of high K(+)- and veratridine-induced membrane

Effects of cyclic AMP on membrane potentials were examined by measuring the changes of bis-oxonol fluorescence in bovine adrenal medullary chromaffin cells. 8-Bromo cyclic AMP (8Br-cAMP) or forskolin caused a gradual and long lasting increase of the fluorescence intensity. The

Immunosuppression by the fungal metabolite cyclosporin A (CsA) is characterized by functional inhibition, rather than destruction of cells. Because activation of immune cells involves intracellular signalling events associated with modulations of cell transmembrane potential (TMP), we tested the ability of

The membrane potential of endothelial cells is an important determinant of endothelial functions, including regulation of vascular tone. We investigated whether adenosine triphosphate-sensitive potassium (K(ATP)) channels were involved in the response of membrane potential to hyperosmolality in cultured human aorta
