gamma-Melanotropin is contained within neurons, nerve fibres and nerve endings of rat duodenum.
Using an immunofluorescence microscopic technique a gamma 3-melanotropin staining is to recognize within neuronal cell bodies and nerve fibres as well as within nerve endings of the rat duodenum. These perikarya have a broad, gamma 3-melanotropin immunofluorescent cytoplasm rim which surrounds a round unstained cell nucleus. They possess often a pear-shaped cell body and are located mainly in the myenteric plexus, but also in the submucous plexus. gamma 3-Melanotropin immunoreactive nerve fibres and nerve fibre-strands are to see in the myenteric plexus neuropil and lamina propria as well as in interconnecting nerve strands lying between the longitudinal and circular smooth muscle layers. Nerve endings immunoreactive to gamma 3-melanotropin are in close association with submucosal blood vessels, probably arterioles, and smooth muscle cells of the circular smooth muscle layer.
