Leptin is a circulating hormone produced primarily by the adipose tissue, which controls food intake and energy homeostasis. Important peripheral actions of leptin involve inhibition of insulin biosynthesis and secretion in pancreatic ß-cells. In turn, insulin stimulates leptin secretion from adipose tissue, establishing a hormonal regulatory feedback loop: ‘adipo-insular axis’. The aim of our study was to determine the interrelations between leptin, insulin/ins...
