Dr. Nikhil V. Dhurandhar is an editor-special issues of the International Journal of Obesity and on the editorial boards of the Korean Journal of Obesity, Journal of Obesity and Metabolic Research, and “The Open Obesity Journal”.

He is serving as President elect of The Obesity Society and is in line to serve as president in 2014-2015.

RESEARCH INTERESTS

Dr. Dhurandhar et al were the first to identify obesity promoting effects of an avian adenovirus (SMAM-1) and a human adenovirus (Ad36). SMAM-1 and Ad36 cause obesity in animal models and show association with human obesity, and coined the term “Infectobesity – obesity of infectious origin”. Subsequently, other researchers have identified additional adenoviruses that induce obesity and have also confirmed the adipogenic effects of Ad36. In summary, he believes that simple explanations for causes of obesity are inadequate and novel approaches are required for its effective treatment and prevention. Obesity of infectious origin is the current focus of Dhurandhar’s lab. Seven viruses have been reported to cause obesity in animal models by various research groups. We reported the first human virus, an adenovirus (Ad-36), which causes adiposity in chickens, rodents and non-human primates and shows association with human obesity. His in-vivo and in-vitro data show that Ad-36 increases adiposity, lowers serum lipids, increases insulin sensitivity and preadipocyte differentiation.

Treatment of obesity is his other major research interest. Considering the limited success of conventional weight loss approaches in long term maintenance, he believes that additional and novel strategies are required to enhance long term weight loss and maintenance. To this effect, his research efforts have included anti-obesity drug trials, various meal replacement strategies and use of eggs as supplement to weight loss efforts.

The lab is currently investigating the molecular mechanism involved in adiposity promoting effect of Ad-36. Several genes of adipocyte differentiation pathway are up-regulated by Ad-36 and E4 orf1 is a viral gene contributing to the effect. We are determining the interaction of the viral and cellular genes involved in the process.

Our long-term goal is to discover treatment and / or prevention of Ad-36-induced adiposity. Furthermore, determining the role of other infectious agents in etiology of obesity is an important area of investigation.
