Feeding in response to glucoprivation induced by 2-deoxy-D-glucose (2-DG) is impaired in genetically obese (Zucker) rats. Muscimol, a GABAA-agonist (0.5 nmol/0.5 microliter in each area) increased food intake in lean rats over 3 h but in fatty rats only at 30 min after infusion into the VMH.
The neuropeptides orexin A and orexin B (also known as hypocretin 1 and hypocretin 2), produced in lateral hypothalamic neurons, are critical regulators of feeding behavior, the reward system, and sleep/wake states. Orexin-producing neurons (orexin neurons) are regulated by various factors involved
Glucagon-like peptide 1 (GLP-1) is a potent inhibitor of food intake. GLP-1 receptor mRNA is densely expressed in hypothalamic arcuate nucleus (ARC) and precisely overlaps the area occupied by proopiomelanocortin (POMC) neurons. Activation of POMC neurons suppresses appetite, and lack of
