Reduced NPY induced feeding in diabetic but not steroid-treated rats: lack of evidence for changes in receptor number or affinity.


Concentrations of the potent hypothalamic appetite stimulating peptide neuropeptide Y (NPY), and its mRNA, are increased in rats with experimental diabetes, suggesting a role in the hyperphagia of this disorder. The 2-h feeding responses to intracerebroventricular (i.c.v.) injection of neuropeptide Y (NPY) (5, 10, and 15 mu g doses) were measured in male… (More)
