Researchers decode an important mechanism through which insulin in the hypothalamus controls the body's energy balance Fat-rich food makes you fat. Behind this simple equation lie complex signaling pathways, through which the neurotransmitters in the brain control the body's energy balance. Scientists at the Cologne-based Max Planck Institute for Neurological Research and the Cluster of Excellence in Cellular Stress Responses in Ageing-associated Diseases (CECAD) at the University of Cologne...

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 author,...

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...

The brain's hypothalamus plays a key role in obesity and one of its major complications "“ type 2 diabetes. Nerve cells in the hypothalamus detect nutrients and hormones circulating in the blood and then coordinate a complex series of behavioral and physiological responses to maintain a balance between calories eaten and calories burned. Obesity and diabetes can result when this regulatory mechanism goes awry. Now, research by postdoctoral fellow Cl©mence Blouet, Ph.D., and Gary...

(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...

All those salty snacks available at the local tavern might be doing more than increasing your thirst: They could also play a role in suppressing social anxiety. New research from the University of Cincinnati (UC) shows that elevated levels of sodium blunt the body's natural responses to stress by inhibiting stress hormones that would otherwise be activated in stressful situations. These hormones are located along the hypothalamic-pituitary-adrenal (HPA) axis, which controls reactions to...

Treatment could help athletes, women with eating disorders Women 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...

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 appearing in the March...

Preventing the vasopressin neurons from swelling, and maintaining their size The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis. Here, the Japanese research team led by Professor Yasunobu OKADA, Director-General of National Institute for Physiological Sciences (NIPS), and Ms. Kaori SATO, a graduate student of The Graduate University for Advanced Studies, clarified the novel function of "vasopressin" that works in the...

A Mayo Clinic researcher says the surprising findings suggest the possibility of a novel treatment for obesity A study by researchers at Mayo Clinic's campus in Florida and Washington University School of Medicine adds a new twist to the body of evidence suggesting human obesity is due in part to genetic factors. While studying hormone receptors in laboratory mice, neuroscientists identified a new molecular player responsible for the regulation of appetite and metabolism. In the Jan. 11...

The hypothalamus is an organ that serves as an important link, along the hypothalamic-hypophyseal axis, between the nervous system and the endocrine system. It is located within the cranial cavity, in the cerebrum, right below the thalamus. It also forms the floor of the third ventricle in the brain. It contains neural pathways, blood vessels, glial cells, and secretory cells—all of which work together to control things like body temperature, hunger, thirst, sleep, and hormonal and...
