| Background Information | Leptin is a hormone primarily produced by adipocytes (fat cells) that plays a critical role in appetite regulation, energy metabolism, and neuroendocrine function. It binds to the leptin receptor (LEPR) in the hypothalamus to regulate food intake and body weight. Recombinant human leptin is widely used in obesity research, metabolic disorder studies, and potential therapeutic applications for leptin deficiency syndromes. |
