Abstract

Radioimmunoassays for cAMP demonstrated that a β-adrenergic agonist, isoproterenol, increased cAMP levels in isolated frog sciatic nerve. Dibutyryl cAMP (db-cAMP) and isoproterenol reduced the amplitude of the compound action potential and decreased the ability of the Xenopus sciatic nerve to follow high frequency stimulation. Similar effects of db-cAMP and a phosphodiesterase inhibitor were seen on intracellularly recorded action potentials of single lobster peripheral axons. These results suggest that cAMP can modulate the electrophysiological response properties of both myelinated and unmyelinated axons.
