Leptin News and Research

RSS

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.

Researchers identify differences in clinical features of non-obese patients with NAFLD

Researchers from the University of Tsukuba identify differences in the clinical features of non-obese patients with non-alcoholic fatter liver disease based on their sex and body mass index.

Study reveals how hormone leptin contributes to weight loss

Some call it baby fat. But recent research has shown that adults have it too--which is a good thing. Brown fat, the so-called good fat that can protect against obesity and associated health risks, like cardiovascular disease and diabetes, is located in small pockets throughout the body.

Obesity could increase severity of influenza study shows

A new study has revealed that those who are obese or overweight tend to get more severe bouts of influenza than those who are a healthy weight. The reason behind this could be the altered immune system of those who are obese. The study outlining this finding is published in the latest issue of the journal mBio from the American Society for Microbiology (ASM). The study was titled, "Obesity-Related Microenvironment Promotes Emergence of Virulent Influenza Virus Strains."

Tailored mesoporous silica particles could be used to treat obesity, diabetes

Engineered ingestible molecular traps created from mesoporous silica particles (MSPs) introduced to the gut can have an effect on food efficiency and metabolic risk factors. The results from studies on mice, published in Nanomedicine, demonstrate the potential to reduce the energy uptake into the body and could lead to new treatments for obesity and diabetes.

Study: Regular exercise reduces cholesterol, protects the cardiovascular system

Regular exercise protects the cardiovascular system by reducing risk factors such as cholesterol and blood pressure. "But we believe there are certain risk factors for cardiovascular disease that are not fully understood," says Matthias Nahrendorf, MD, PhD, of the Center for Systems Biology at MGH.

New discovery paves way for better treatment of diabetes

Insulin, a hormone essential for regulating blood sugar and lipids, is normally produced by pancreatic β cells. In many people with diabetes, however, pancreatic cells are not (or no longer) functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through daily insulin injections.
