Latest Leptin Stories

Women who have higher levels of the appetite-controlling hormone leptin have fewer symptoms of depression, and this apparent inverse relationship is not related to body mass index (BMI), a new study finds. On Monday the results will be presented at The Endocrine Society's 93rd Annual Meeting in Boston."Animal data suggest that leptin may reduce anxiety and improve depression. Our study in women suggests that leptin may indeed have antidepressant qualities," said the study's lead...

Children who are overweight may not be getting enough sleep at night, according to researchers in New Zealand. Their study, published in the online edition of British Medical Journal, followed 244 children between the ages of three and seven. The results showed that more sleep was linked to a lower weight, which could have important public health consequences, The Telegraph reports.UK experts said there was "no harm" in drawing attention to the link between reduced sleep and ill health. The...

Weizmann Institute scientists have added another piece to the obesity puzzle, showing how and why a certain protein that is active in a small part of the brain contributes to weight gain. This research appeared today in Cell Metabolism. Prof. Ari Elson and his team in the Institute's Molecular Genetics Department made the discovery when working with female mice that were genetically engineered to lack this protein, called protein tyrosine phosphatase epsilon (PTPe, for short). The...

(Ivanhoe Newswire) -- It was recently reported that women with low body fat, including runners and dancers as well as women with eating disorders, may be able to restore their fertility and reduce their risk of bone fractures by taking doses of the hormone leptin.Researchers at Beth Israel Deaconess Medical Center (BIDMC) offered the first definitive proof that a lack of leptin contributes to hypothalamic amenorrhea (HA) -- a condition in which menstrual periods of women cease, triggering...

Treatment could help athletes, women with eating disordersWomen with extremely low body fat, including runners and dancers, as well as women with eating disorders, are prone to develop hypothalamic amenorrhea, a condition in which their menstrual periods cease, triggering such serious problems as infertility and osteoporosis.Now, a study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) offers the first definitive proof that a lack of leptin contributes to hypothalamic...

(Ivanhoe Newswire)-- The results of a new study on obesity in sheep and lambs may lend a hand in understanding obesity in humans.

Since humans also bear mature offspring, the results of this study are the first that can possibly be applied to humans.While the relationship between maternal obesity and offspring obesity has been proven in...

The research, published today (Tuesday March 15 2011) in The Journal of Physiology, shows a definite link between maternal and offspring obesity and is the first demonstration that this is the case in mammals which bear 'mature offspring' "“ as humans do.Professor Peter Nathanielsz, lead author of the research, said: "A relationship between maternal obesity and offspring obesity has been clearly identified in rodents but as their young are born immature, it was not clear whether the...

Researchers at UT Southwestern Medical Center have identified a signaling pathway in the brain that's sufficient to induce cellular leptin resistance, a problem that decreases the body's ability to "hear" that it is full and should stop eating."Leptin resistance is a significant factor, yet the mechanisms that underlie the problem remain unclear," said Dr. Joel Elmquist, professor of internal medicine and pharmacology at UT Southwestern and senior author of the study...
