Leptin is essential for energy intake and expenditure. It is one of the most important adipose-derived hormones, being primarily expressed in adipocytes of white adipose tissue. Loss of function of Leptin creates an uncontrolled appetite leading to severe obesity and abnormal metabolism, making this a useful model for the study of lifestyle diseases, such as obesity, diabetes, atherosclerosis, high cholesterol and high blood pressure.
