K+ efflux has been analyzed in human erythrocytes incubated in a K+ free medium containing ouabain, bumetanide, CaCl2, and the Ca2+ ionophore A23187. In these conditions, a K+ efflux, which is exponentially dependent on the concentration of A23187 present in the medium, has been observed. This flux is almost completely abolished by either quinine or EGTA, so that, the above K+ efflux has been considered Ca2+ dependent. The effects of cAMP, and cGMP, have been tested on this flux. Ca2+ dependent K+ efflux decreases in presence of millimolar concentrations of cAMP in the medium. The addition of methyl-isobutyl-xanthine to the incubation medium containing cAMP enhances the inhibitory effect of this compound. cGMP also inhibits the Ca2+ dependent K+ efflux. Our results suggest that cyclic nucleotides may modulate the activation of Ca2+ dependent K+ channels in human erythrocytes.
