Common virus may contribute to obesity in some people

A common virus may be a contributing factor to the obesity epidemic sweeping through the United States and other countries, according to a new study by scientists in Louisiana. In laboratory experiments they showed that infection with human adenovirus-36 (Ad-36), long recognized as a cause of respiratory and eye infections in humans, transforms adult stem cells obtained from fat tissue into fat cells, whereas stem cells not exposed to the virus were unchanged, according to Magdalena Pasarica and colleagues.

The scientists also reported identification of a specific gene in the virus that appears to be involved in this obesity-promoting effect. The findings could lead to a vaccine or antiviral medication to help fight viral obesity in the future, the scientists said.

Were not saying that a virus is the only cause of obesity, but this study provides stronger evidence that some obesity cases may involve viral infections, Pasarica stated.
