Nutrient Sensing and Anorexia via Neuropeptides
2018
: Various neuropeptides play an essential role in the nutrient sensing mechanism and related homeostasis. Nesfatin-1 is a newly identified neuropeptide having anorectic activity, and nesfatin-1-containing neurons are widely distributed in the brain, including the hypothalamus and brain stem. Our previous study showed that dehydration-induced anorectic effects are mediated via the central nesfatin-1 pathway in rats. Our recent studies have also shown that peripheral anorectic peptides (cholecystokinin-8, glucagon-like peptide-1, and leptin) and an antineoplastic agent (cisplatin) caused inhibition of feeding via the central nesfatin-1 pathway in rats. Nesfatin-1-containing neurons in the central nervous system, in particular the hypothalamus and the brain stem, may mediate peripheral nutrient signals and regulate feeding behavior.
