Anorexigenic effects of central adrenomedullin are associated with hypothalamic changes in juvenile Gallus gallus.

Adrenomedullin (AM), a 52 residue neuropeptide, is associated with anorexia in mammals and has a poorly understood central mechanism of action. Thus, this study focused on elucidating AM's central mechanism of action in an alternative vertebrate model, the chick (Gallus gallus). In Experiment 1, chicks centrally injected with AM dose-dependently reduced food but not water intake.
