In rats, the hyperphagia induced by a 48 h fast, or a hypoglycemic hyperinsulinemic clamp, or uncontrolled diabetes, was completely s...

9.5. A synaptic amplifier of hunger for regaining body weight in the hypothalamus

K Grzelka , H Wilhelms , S Dodt , ML Dreisow , JC Madara , SJ Walker , C Wu , D Wang , BB Lowell , H Fenselau

Brief summary: Grzelka et al. identified a hypothalamic circuit that regulates regain of body weight after weight loss.Body weight is one of the most regulated variables of our body, which is most likely due to the evolutionary history of times when access to food was scarce and volatile. Weight loss triggers a strong counterregulatory response. It increases the hunger drive and greatly increases the reward value of food, making it more difficul...

To read the full abstract: Elife. 2018 Jun 15;7. pii: e35960.Using transgenic mice, this team discover a new role for Pituitary adenylate cyclase activating polypeptide (PACAP) in female puberty and reproduction. This neuropeptide relays nutritional state information in the hypothalamus to regulate gonadotropin-releasing hormone release.Metabolic cues play...
