Leptin News and Research RSS Feed - Leptin News and Research

Leptin is a 16 kDa protein hormone that plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism. It is one of the most important adipose derived hormones. The ''Ob(Lep)'' gene (Ob for obese, Lep for leptin) is located on chromosome 7 in humans.

Women suffering from anorexia nervosa or obesity may respond differently to taste

Researchers at the University of Colorado Anschutz Medical Campus have discovered that women suffering from anorexia nervosa and those who are obese respond differently to taste, a finding that could lead to new treatments for the eating disorders. [More]
McGill researchers discover brain cells that play key role in leptin sensing, weight gain

McGill researchers discover brain cells that play key role in leptin sensing, weight gain

It's rare for scientists to get what they describe as "clean" results without spending a lot of time repeating the same experiment over and over again. But when researchers saw the mice they were working with doubling their weight within a month or two, they knew they were on to something. [More]
Human milk hormones may play vital role in shaping healthy infant microbiome

Human milk hormones may play vital role in shaping healthy infant microbiome

A new University of Colorado Anschutz Medical Campus study finds that hormones in breast milk may impact the development of healthy bacteria in infants' guts, potentially protecting them from intestinal inflammation, obesity and other diseases later in life. [More]

Small piece of detoxified E. coli wall makes mice lose natural sweet tooth, study finds

Putting just a tiny piece of the wall of detoxified E. coli into their gut make mice lose their natural sweet tooth, researchers report. [More]
Findings could help explain origin of type 2 diabetes in children of obese mothers

Findings could help explain origin of type 2 diabetes in children of obese mothers

A new study led by researchers at The Saban Research Institute of Children's Hospital Los Angeles reports that the presence of leptin - a hormone secreted by fat cells that is critical to maintaining energy balance in the body -- inhibits the prenatal development of neuronal connections between the brain and pancreas. The findings could help explain the origin of type 2 diabetes, particularly in children of obese mothers. [More]
Scientists explore new treatment avenues to protect obese individuals from cardiovascular disease

Scientists explore new treatment avenues to protect obese individuals from cardiovascular disease

Fatness is clearly linked to cardiovascular disease, but scientists want to find why the unhealthy pair tend to go hand-in-hand and how to break up their relationship. [More]
Regulatory immune cells compromised in PAH

Regulatory immune cells compromised in PAH

Research suggests that regulatory T cells may play a part in all subtypes of pulmonary arterial hypertension. [More]
Metabolic syndrome treatment benefits MS patients

Metabolic syndrome treatment benefits MS patients

Oral antidiabetic medications have beneficial anti-inflammatory effects in patients with multiple sclerosis and metabolic syndrome, providing support for a link between metabolism and autoimmunity, researchers report. [More]
Rockefeller research reveals vital new component of system responsible for regulating food intake

Rockefeller research reveals vital new component of system responsible for regulating food intake

The molecular intricacies of hunger and satiety, pivotal for understanding metabolic disorders and the problem of obesity, are not yet fully understood by scientists. However, new research from The Rockefeller University reveals an important new component of the system responsible for regulating food intake: a hormone called amylin, which acts in the brain to help control consumption.

Studies explore causative factor of hypertension in younger, obese men and women

Studies explore causative factor of hypertension in younger, obese men and women

There's no doubt estrogen plays a big role in the differences between males and females, and now researchers want to know if it also helps explain emerging sex differences in what makes younger, obese men and women hypertensive. [More]
Irregular sleep schedules linked to adverse metabolic health in midlife women

Irregular sleep schedules linked to adverse metabolic health in midlife women

A new study suggests that frequent shifts in sleep timing may be related to adverse metabolic health among non-shift working, midlife women. [More]
Weekend junk food binges bad for your gut health

Weekend junk food binges bad for your gut health

Yo-yoing between eating well during the week and bingeing on junk food over the weekend is likely to be just as bad for your gut health as a consistent diet of junk, new UNSW research suggests. [More]
Leptin gene therapy aids weight loss without significant side effect of bone loss

Leptin gene therapy aids weight loss without significant side effect of bone loss

Delivering the hormone leptin directly to the brain through gene therapy aids weight loss without the significant side effect of bone loss, according to new collaborative research from Oregon State University and University of Florida. [More]
High levels of satiety hormone leptin contribute to cardiovascular disease in obese individuals

High levels of satiety hormone leptin contribute to cardiovascular disease in obese individuals

While high levels of the satiety hormone leptin don't help obese individuals lose weight, they do appear to directly contribute to their cardiovascular disease, researchers report. [More]
High dietary iron intake suppresses hormone that regulates appetite

High dietary iron intake suppresses hormone that regulates appetite

Here's one more reason to cut down on the amount of red meat you eat. Using an animal model, researchers at Wake Forest Baptist Medical Center have found that dietary iron intake, equivalent to heavy red meat consumption, suppresses leptin, a hormone that regulates appetite. [More]
Improved method for building proteins into antibodies

Improved method for building proteins into antibodies

Some proteins exist so fleetingly in the bloodstream that they can't be given effectively as therapies. However, building them into larger proteins, such as antibodies, can make them persist long enough to be useful. Now a team led by scientists at The Scripps Research Institute (TSRI) has devised an improved method for accomplishing this protein-engineering feat. [More]

New study shows high-fat diet can cause impairments in functioning of mesolimbic dopamine system

New study shows high-fat diet can cause impairments in functioning of mesolimbic dopamine system

High-fat feeding can cause impairments in the functioning of the mesolimbic dopamine system, says Stephanie Fulton of the University of Montreal and the CHUM Research Centre. This system is a critical brain pathway controlling motivation. Fulton's findings, published today in Neuropsychopharmacology, may have great health implications. [More]
UC Riverside researchers explore effects of early-life exercise

UC Riverside researchers explore effects of early-life exercise

More than one in three adults in the United States is considered to be obese. What impact can exercise done early in life have on the propensity for exercising during the adult years? A team of researchers at the University of California, Riverside did experiments on mice in the lab to find out. Specifically, they evaluated the effects of early exercise on adult physical activity, body mass, food consumption and circulating leptin levels. [More]
