Neuropeptide Y afferents have synaptic interactions with histaminergic (histidine decarboxylase-immunoreactive) neurons in the rat brain.
The synaptic interaction was identified between histaminergic cells and neuropeptide Y (NPY)-immunoreactive axon terminals in the caudal magnocellular nucleus, by means of the immunoelectron microscopic mirror method. This observation suggests that NPY afferents exert monosynaptic influences upon the functioning of the central histaminergic neuronal system.
