I Knew It Wasn't Your Fault

How much does a fat promoting virus contribute to obesity?

As an alternative, Drs. Magdalena Pasarica and Nikhil Dhurandhar of Louisiana State University used the virus to infect fat tissue taken from people undergoing liposuction. Pasarica reported that more than half the stem cells in the tissue were converted to fat cells and began growing as they accumulated and stored fat.

Once fat cells are formed in the body, she noted, they never go away. They can be shrunk, but they remain, waiting for a fresh infusion of fat so they can begin growing again.
