Background and aimsGhrelin, the natural ligand of the growth hormone secretagogue receptor 1a, is the most powerful peripherally active orexigenic agent known. In rodents, ghrelin administration stimulates growth hormone release, food intake, and adiposity. Because of these effects, blocking of ghrelin has been widely discussed as a potential treatment for obesity. Spiegelmer NOX‐B11 is a synthetic l‐oligonucleotide, which was previously shown to bind ghrelin. We examined the effects of NOX‐B11 on ghrelin induced neuronal activation and food intake in non‐fasted rats.
