title: Enterostatin suppresses food intake following injection into the third ventricle of rats.
abstract: The effect on food intake of an activation peptide from pancreatic pro-colipase, called enterostatin, has been studied after parenteral or third ventricular administration. The activation peptide (enterostatin = Val-Pro-Asp-Pro-Arg = VPDPR) reduced food intake when given intraperitoneally. Low doses of this peptide also reduced food intake when given into the third ventricle, but high doses were ineffective. Enterostatin did not modify the stimulatory effects on food intake of clonidine, an alpha 2-adrenergic agonist, suggesting that its anorectic effects are not mediated via the alpha 2-adrenergic system. These data suggest that enterostatin, an activation peptide from pro-colipase, may play a role in producing satiety.
