A chemical produced by the adipose cells that seems to signal that plenty of fat is stored and that no more fat is needed. This signal may diminish eating.
Acts as a signal of how much fat is in the body to the brain's hypothalamus, which coordinates basic body functions such as eating. Differences in the fat's production rate of leptin, resistance to leptin at its site of action or a combination of these factors could influence eating behaviors and energy use to cause obesity or other nutritional abnormalities, such as diabetes.
A hormone synthesized by fat cells and thought to be involved in the regulation of feeding behavior.
A hormone produced by fat cells for regulation of appetite. It controls how much you want to eat, how much of the food your body stores, and how much is used for energy.
A peptide hormone that is produced by fat cells. It plays a role in body weight regulation by acting on the hypothalamus to suppress appetite and burn fat stored in adipose tissue.
Greek, leptos = thin) a polypeptide hormone (16 kDa) produced in adipose and many other tissues. Hormone receptor (OB-R, leptin receptors) found in many different tissues. Hormone levels associated with fertility and reproductive maturity in many species. Other hormonal roles include: satiety, adiposity, and metabolism, body mass control, angiogenesis, immunity, wound healing, bone remodelling cardiovascular function, and specific metabolic pathways.

hormone produced by fat cells that participates in control of food intake
discovered by Jeffrey Friedman and colleagues in 1994. Fat tissue secretes it into the bloodstream where it travels to the brain and acts on specific neurons in the hypothalamus.
hormone made by fat cells. ItÂ's also a cytokine that participates in regulating body mass, and storing fatty acids efficiently. It also activates production of MSH, which in turn regulates much of the immune response from the innate immune system. High leptin and low MSH are the markers for obesity caused by toxins. With high leptin in a biotoxin patient, weight loss is incredibly difficult
This protein was been portrayed as the way to a cure for obesity. Leptin was first described as an apiodocyte - derived signaling factor, which, after interaction with its receptors, induced a complex response, including control of bodyweight and energy expenditure. It could be quite a fat burner. Research shows that people who used high doses of leptin for six months lost weight, most of it bodyfat.
A hormone produced by fat cells that indicates the degree of hunger to the brain in order to control the storage of body fat. Leptin was discovered in 1984.
A hormone that has a central role in fat metabolism. Leptin was originally thought to be a signal to lose weight but it may, instead, be a signal to the brain that there is fat on the body. See the entire definition of Leptin
a hormone that acts in the brain to control appetite.
A hormone produced by fat cells that has been suggested to promote satiety and reduce caloric consumption. When leptin levels are low, hunger is increased. Sleep loss is associated with diminished leptin levels.
regulatory hormone produced by fat cells; when released into the circulation, it influences the hypothalamus to control appetite.
A hormone produced by the ob (obese) gene and secreted by fat tissue that acts on the brain to regulate appetite (See Weight Management).
Leptin (from the Greek word leptos, meaning thin) is a 16 kDa protein hormone that plays a key role in regulating energy intake and energy expenditure, including the regulation of appetite and metabolism.
