Liposuction-like procedure may harm body's immune system

A liposuction-like procedure called lipectomy results in a loss of humoral immune protection in two commonly studied rodent models, the prairie vole and the Siberian hamster, scientists have found. The report by a team of researchers at Indiana University, Ohio State University and Johns Hopkins University was made available online this week by The Royal Society. Their study is the first to show that even a moderate loss of fat leads to decreased amounts of infection-fighting IgG antibodies.
