Topic: ghrelin receptors

Food odours are perceived before consumption and trigger physiological responses (e.g., appetite, saliva, digestive enzymes) to help the body prepare for ingestion. Importantly, smell perception through the olfactory bulb (OB) increases when hungry. The mechanism linking metabolism and olfaction remains unknown, but there is converging evidence that the olfactory system is a target for metabolic hormones associated with food intake regulation and may adapt the olfactory system to nutritional needs by promoting or inhibiting food-seeking. Here, we looked at the hormone ghrelin as a signal of en
