New obesity-related genes identified
A large international consortium has made significant inroads into uncovering the genetic basis of obesity, adding six new genetic variants to the two already linked to higher body mass index (BMI) in previous studies. Most of the newly discovered genes had never before been suspected of having a role in body weight and, curiously, many…

Protective mechanism fails when obesity sets in
Reporting in the journal Cell Metabolism, researchers from the Harvard School of Public Health (HSPH) said they have shown for the first time that fat-storing cells, or adipocytes, contain a protective anti-inflammatory immune mechanism that prevents the cells from overreacting to inflammation-causing stimuli, such as fatty acids in the diet.
