Increase in membrane conductance by adrenaline in parotid acinar cells.
It is shown that excitation of the alpha- or beta-adrenoceptors in mouse parotid acinar cells causes a marked reduction of surface cell membrane resistance. The alpha-adrenoceptor induced membrane effect is an increase in K conductance. The beta-adrenoceptor induced membrane effect does not seem to be mediated by cyclic AMP.
