Differential inhibition of galanin- and ghrelin-induced food intake by i.c.v. GLP-1(7-36)-amide.

Feeding regulation involves both anorectic and orexigenic neuropeptides mainly located in the hypothalamus. To gain further insight into the interaction between these two groups of regulators inhibition of feeding induced by glucagon-like peptide-1 (GLP-1) was examined during stimulation of food intake by equimolar doses of ghrelin and galanin. The experiments were carried out in freely feeding rats.
