New finding links obesity and high-fat, high-sugar diets with changes in inflammatory status

New research in The FASEB Journal suggests that an abnormal amount of an inflammatory protein called PAR2 is present on abdominal fat tissues of overweight and obese humans and rats

Scientists have moved a step closer to an "obesity drug" that may block the effects of diets high in sugar and fats. In a new research report published in the December 2013 issue of The FASEB Journal, scientists show that there is an abnormal amount of an inflammatory protein called PAR2 in the abdominal fat tissue of overweight and obese humans and rats. This protein is also increased on the surfaces of human immune cells by common fatty acids in the diet. When obese rats on a diet high in sugar and fat were given a new oral drug that binds to PAR2, the inflammation-causing properties of this protein were blocked, as were other effects of the high-fat and high-sugar diet--including obesity itself.

"This important new finding links obesity and high fat high sugar diets with changes in immune cells and inflammatory status, highlighting an emerging realization that obesity is an inflammatory disease," said David P. Fairlie, Ph.D., study author from the Institute for Molecular Bioscience at the University of Queensland, in Bribane, Australia. "Drugs designed to block certain inflammatory proteins, as in this report, may be able to prevent and treat obesity, which in turn is a major risk factor for type 2 diabetes, heart disease, stroke, kidney failure, limb amputation, and cancers."
