STUDY: OBESITY MAY BE LINKED TO A TREATABLE VIRUS

Posted in Health Watch, News Brief, Stem Cell Research on August 21st, 2007

LOUISIANA SCIENTISTS DISCOVER THAT THE VIRUS RESPONSBLE FOR COLDS AND EYE INFECTIONS COULD BE CAUSING STEM CELLS TO CHANGE INTO FAT CELLS

A team at Louisiana’s Pennington Center found that a common virus could cause stem cells to change into fat cells in lab experiments.

Researchers told the American Chemical Society conference anti-viral treatments might be possible.

But UK experts said the idea of obesity as an infectious illness was unlikely.

The properties of adenovirus-36, long known as a cause of colds and eye infections, have been under investigation for several years, with animal experiments suggesting that it might have some connection to the laying down of fat cells.

The idea that a virus could be a factor in some cases of obesity has not found widespread support, with most insisting that weight gain can be explained far more simply through poor diet and lack of exercise.

The Pennington team’s latest research uses human stem cells in the laboratory.

Stem cells are the body’s “master cells”, and scientists have been gradually unlocking the secrets of how they are transformed to make new tissue.

The researchers extracted stem cells from fatty tissue taken from liposuction patients, and exposed some to adenovirus-36.

After the cells were left for a week, those exposed to the virus had changed into human fat cells, while those left to grow without the virus had not.
