Hypothalamus News and Research

RSS

The Hypothalamus is the area of the brain that controls body temperature, hunger, and thirst.

Transplantation of new neurons into damaged area of the brain could restore brain functions

Without neurons reacting to the blood leptin level, the brain does not control the feeling of hunger and fullness. This type of genetic defects results in severe obesity in humans and animals.

Researchers take a step toward neuronal replacement therapy

A new study has revealed that immature neurons taken from healthy mouse embryos can repair damaged brain circuitry and partially normalize metabolism when transplanted into adult mice that have grown morbidly obese due to a genetic deficiency.

Carefully selected young, healthy neurons can repair brain circuitry

Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.

Alzheimer’s disease progression and body weight may be linked: Study

There have been studies that show that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight. However some studies also show that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI).

Study examines link between early-stage Alzheimer's and lower BMI

Studies have shown that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight, yet researchers have also found that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI). A current study examines this relationship between Alzheimer's disease and BMI.

CUMC presents 2011 Naomi Berrie Award to UMDNJ researcher

Columbia University Medical Center (CUMC) presented the 2011 Naomi Berrie Award to Barry E. Levin, MD, a University of Medicine & Dentistry of New Jersey researcher whose work focuses on the mechanisms by which specialized metabolic-sensing neurons regulate glucose and energy homeostasis. Junior investigator Kazuhisa Watanabe, at Columbia University Medical Center, received a Berrie Fellow award.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

Brain plays a key role in regulating glucose metabolism in humans

Researchers at Albert Einstein College of Medicine of Yeshiva University have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.

Scientists discover neurons responsible for light-induced arousal response

Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

Scientists reveal how resistance to hormone leptin develops

The effects of obesity - both on our bodies and on the health budget - are well known, and now, scientists are getting closer to understanding how the disease progresses, providing clues for future treatments.

Reducing levels of protein FKBP51 may yield new antidepressant therapies

Decreasing expression of a protein associated with susceptibility to depression made old mice resistant to depressive-like behavior while improving their hormonal response to stress, a study led by researchers at the University of South Florida found. The lack of this protein, FKBP51, did not adversely affect their memory, learning, or basic motor functions.

Elevating free radical levels suppresses appetite in obese mice

Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals-molecules tied to aging and tissue damage-are at the heart of increased appetite in diet-induced obesity.

GCC hormone receptor may also help fight obesity

The hormone receptor guanylyl cyclase C (GCC) has been established as a suppressor of colorectal cancer tumors, but new evidence from Thomas Jefferson University suggests it may also help fight one of the country's biggest pandemics: obesity.

New insights into sleep difficulties among older people

A new study of the brain's master circadian clock - known as the suprachiasmatic nucleus, or SCN - reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

Texas Children's Hospital uses new surgical approach for treating epilepsy

Texas Children's Hospital is the first hospital in the world to use real-time MRI-guided thermal imaging and laser technology to destroy lesions in the brain that cause epilepsy and uncontrollable seizures.

Lorcaserin Phase 3 trial data on type 2 diabetes to be presented at ADA 2011

Arena Pharmaceuticals, Inc. and Eisai Inc. announced today that lorcaserin data from the Phase 3 BLOOM-DM trial will be presented in poster sessions at the American Diabetes Association's (ADA) 71st Scientific Sessions in San Diego, California.

GTx commences Capesaris Phase IIb trial in advanced prostate cancer

GTx, Inc., announced today that it initiated a Phase IIb clinical trial evaluating Capesaris, a selective estrogen receptor alpha agonist, compared to Lupron Depot for first line treatment of advanced prostate cancer.

Smoking keeps weight off: Study finds out how

The researchers have found that nicotine activates a pathway in the brain that suppresses appetite. The study was published in the journal Science. The authors believe this discovery should lead to better diet drugs.

High-fat diet may cause brain nerve cell injury

Obesity among people who eat a high-fat diet may involve injury to neurons, or nerve cells, in a key part of the brain that controls body weight, according to the authors of a new animal study. The results will be presented Tuesday at The Endocrine Society's 93rd Annual Meeting in Boston.

Consumption of high-fat food causes more insulin to be released by the pancreas and leads to obesity

Fat-rich food makes you fat. Behind this simple equation lie complex signalling pathways, through which the neurotransmitters in the brain control the body's energy balance.
