title: Electron microscopic immunohistochemical localization of alpha-msh in the rat brain.
abstract: Using an immunohistochemical technique at the electron microscopic level, it has been shown that alpha-MSH is localized within the small vesicles of a few cell bodies found in the arcuate nucleus and numerous nerve fibers widely distributed throughout the brain. These findings suggest that alpha-MSH could possibly be considered as a neurotransmitter.
