The effects of the Y2 receptor agonist neuropeptide Y NPY-(13-36) on the depolarization-evoked release of [3H]noradrenaline (NA) from synaptosomal preparations of the medulla oblongata, the hypothalamus, the hippocampal formation and the parieto-occipital cortex of the male rat were studied. NPY-(13-36) (0.1-100 nM) caused a concentration-related inhibition of the depolarization-induced release of [3H]NA in all areas studied, except the parieto-occipital cortex. The results indicate that NPY Y2 receptors are present on NA terminals in all areas studied, except the parieto-occipital cortex and inhibit depolarization-evoked [3H]NA release.

Abstract

The effects of the Y2 receptor agonist neuropeptide Y NPY-(13-36) on the depolarization-evoked release of [3H]noradrenaline (NA) from synaptosomal preparations of the medulla oblongata, the hypothalamus, the hippocampal formation and the parieto-occipital cortex of the male rat were studied. NPY-(13-36) (0.1-100 nM) caused a concentration-related inhibition of the depolarization-induced release of [3H]NA in all areas studied, except the parieto-occipital cortex. The results indicate that NPY Y2 receptors are present on NA terminals in all areas studied, except the parieto-occipital cortex and inhibit depolarization-evoked [3H]NA release.
