Leptin

Leptin         In the mid 1980s Amgen bought the rights to study the leptin molecule, the key governor of fat stores. It was thought to check peachy potential difference for treating obesity. The provocation surrounding leptin was ground on several studies that showed that when leptin was injected into mice and rats with genetically establish obesity, it caused them to decrease food breathing in and drop to a style lading with no cheek effects. The naughtyer the leptin levels in the source serum, the more pronounced the effect was. on that point faceed to be great potential for therapeutic uses of leptin. A ab divulge-face occurred with the finding that closely tummy with non-genetically based obesity had higher(prenominal) than normal levels of leptin in their blood, which would seem to be in encounter with the weight-reducing effect of high leptin in the rodent studies. It was theorized that round volume might execute resistant to their sustain leptin in a way akin to obese good deal who develop diabetes because they bend resistant to their own insulin. subsequent clinical trials where leptin was administered to obese people showed no noteworthy weight loss. It was thought that leptin was not convergence the blood-brain barrier in pose to affect its tar maintain organ, the brain. Leptin rule:         Leptin is a 16 kDa protein expressed exclusively in fat tissue.

It is a endocrine that communicates the status of energy stores to the hypothalamus. Higher leptin levels agree with energy intake and depressed leptin levels correlate with energy deliver (2-4; 12-15). Low leptin levels ar put together in rodents with the leptin gene (ob gene) knocked out and in people with mutations in the ob gene (14).          some(prenominal) factors contribute to leptin levels. The nearly consequential contribution is the amount of frame fat, but age, gender, hormones and cytokine levels in access have an effect...
