Effect of diazoxide on brain capillary insulin receptor binding and food intake in hyperphagic obese Zucker rats.

Insulin is believed to act as a central adiposity signal by binding to hypothalamic and other brain insulin receptors. Entry of circulating insulin into the brain is accomplished by a saturable receptor-mediated transendothelial transport system and is believed to be impaired in hyperinsulinemic, insulin-resistant, and hyperphagic obese Zucker rats… CONTINUE READING
