Popis: Venlafaxine, a dual amine reuptake inhibitor, was utilized to delineate the role of the individual aminergic components of the `serotonin/noradrenaline link' in modifying receptor-linked second messenger cascades. Venlafaxine (20 mg/kg i.p. bid for 10 days) failed to alter in normal animals either the density of β adrenoceptors or the response of the β adrenoceptor-coupled adenylate cyclase system to noradrenaline but significantly decreased the cyclic AMP response to noradrenaline in the brain of rats with selective depletion of brain serotonin by p-chlorophenylalanine. The studies provide evidence for a cross-talk between noradrenergic and serotonergic receptor cascades at the level of mechanisms involved in the desensitization of the β adrenoceptor-coupled adenylate cyclase system.
