Kraicer J, Lussier B, Kotanen S, Moor BC. Neuropeptide Y does not inhibit the release of alpha-MSH from the pars intermedia of the rat adenohypophysis. Can J Physiol Pharmacol. 1988;66(4):318-20.
Neuropeptide Y in concentrations from 10(-8) to 10(-6) M inhibits the release of alpha-MSH from the frog (Rana pipiens) pituitary in a reversible, sustained, and concentration-related manner. However, it does not inhibit the release of alpha-MSH from the rat pars intermedia. Thus, while neuropeptide Y may play a role in the control of alpha-MSH release in amphibia, it appears not to be a regulatory peptide for the mammalian pars intermedia.
