Fettväv kommer att tillverka pro-inflammatoriska hormoner såsom leptin, a potential role in central nervous system, cardiovascular and gastrointestinal function
( 1 ) The nickname “the starvation hormone” has been given to leptin because levels tend to plummet when someone restricts their calorie intake too much, exercises more and loses body fat. Leptin, a pleiotropic protein has long been recognized to play an important role in the regulation of energy homeostasis, metabolism, neuroendocrine function, and other physiological functions through its effects on the central nervous system (CNS) and peripheral tissues. Leptin is secreted by adipose tissue and encoded by the obese (ob) gene. Leptin acts as a central mediator which regulates Leptin appears to function largely within the long-term system and influences the quantity of food con-sumed relative to the amount of energy that is expended. Leptin level does not increase significantly after a meal and does not, by itself, lead to the termination of a meal.10 These results suggest that leptin is not a classic satiety factor.
Leptin deficiency (Montague et al. 1997) and leptin receptor defects (Clement et al. 1998) in humans are very rare. On average, serum leptin is usually elevated in obesity and is positively correlated with body mass index, percentage of body fat and fat mass (Considine et al.

Moreover evidence is mounting that in addition to its hypothalamic actions, leptin has widespread actions in the CNS. Leptin, a pleiotropic protein has long been recognized to play an important role in the regulation of energy homeostasis, metabolism, neuroendocrine function, and other physiological functions When leptin function is disrupted, you gain weight. You can even become leptin resistant , where you overeat and gain weight because your brain doesn’t get the signal to stop.

Genom (obesitas är latin för övervikt) i möss har man fått fram djur som inte bildar så mycket leptin och därför lätt blir feta. Kontakt: Skicka e-post till redaktionen. The functioning of leptin is actually negative feedback, that is, when the hypothalamus detects enough fat reserves, it inhibits intake and anabolism (.

Leptin appears to function largely within the long-term system and influences the quantity of food con-sumed relative to the amount of energy that is expended. Leptin level does not increase significantly after a meal and does not, by itself, lead to the termination of a meal.10 These results suggest that leptin is not a classic satiety factor.
Function Initially, leptin was known to be secreted by fat tissue, and circulate at levels directly proportional to the total amount of fat in the body [ 3 ]. However, it is now considered a multifunctional hormone that is produced by various tissues and organs including the placenta [ 4 ], kidney [ 5 ], salivary glands [ 6 ], and stomach [ 7 ].

Leptin deficiency or resistance can result in profound obesity, diabetes, and infertility in humans.
Leptin acts on leptin receptors (LEPRs), which are widely Here, current knowledge about the role of leptin in the regulation of blood pressure and in the pathogenesis of arterial hypertension is presented. Leptin acts on human marrow stromal cells to enhance differentiation to osteoblasts and to inhibit differentiation to adipocytes.
