Sympathetic nerves of the pineal gland contain both serotonin and norepinephrine. Inhibition of norepinephrine synthesis with a tyrosine hydroxylase inhibitor, a-methyl-p-tyrosine (aMPT) , causes an elevation of pineal serotonin. The administration of dopamine or norepinephrine blocks the elevation
Background: The pineal gland is richly innervated by the neuropeptide Y (NPY)-positive nerves that mostly exibit immunoreactivity for the enzyme tyrosine hydroxylase, a marker of sympathetic nerve fibers. NPY is synthesized as a part of larger prepromolecule. The present study was undertaken to demo
