Abstract
This study investigated the role of cyclic AMP in the inhibition of [3H]5-hydroxytryptamine ([3H]5-HT) release mediated through the 5-HT1D autoreceptor using slices of guinea-pig cerebral cortex. Forskolin, dibutyryl-cyclic AMP and rolipram, which increase intracellular cyclic AMP by different mechanisms, all attenuated the inhibitory effect of the autoreceptor agonist 5-carboxamidotryptamine. These results indicate that modulation of cyclic AMP production affects 5-HT1D autoreceptor function.
