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.
Oral treatment of diet-induced obese rats attenuated PAR2 signaling in adipose tissue and inhibited adipose inflammation, insulin resistance, diet-induced obesity and cardiovascular abnormalities. This is the first report that a PAR2 antagonist improves obesity, glucose homeostasis and obesity-associated chronic inflammation in vivo. These findings indicate that increased PAR2 expression may be a valuable new biomarker for metabolic dysfunction and further, that PAR2 antagonism can be an effective intervention for treating metabolic dysfunction and obesity.
The bottom line of this report is that obesity is an inflammatory disease, and inflammation plays a greater role in the downward spiral to obesity than most people realize. [emphasis mine]
