Leptin receptor. Molecular model of a leptin receptor complexed with an antibody. Leptin is a hormone produced by adipose (fat) tissue. It interacts with receptors in the brain's hypothalamus to signal when a person is full. It also circulates in the blood at levels proportionate to body fat, which allows the brain to regulate appetite and metabolism.
