Fat cells become useful stem cells in tissue reconstruction

Tampa, Fla. (Dec. 23, 2010) — Two studies appearing in the current issue
of Cell Transplantation 19(10) discuss stem cells derived from adipose (fat) cells and their potential use in plastic surgery and tissue reconstruction. The studies are now…

Leptin regulates the immune response to friend and foe

The hormone leptin, primarily produced in fat cells, helps regulate food intake, metabolism and reproduction. It has also been shown to promote and sustain the body’s immune response by binding to T lymphocytes – the frontline cells that protect against infection.
The disease experimental autoimmune encephalomyelitis (EAE) in mice is currently used by researchers as a model of human multiple sclerosis (MS). Italian researchers now reports that just prior to developing the clinical symptoms of EAE, mice experience a significant burst of leptin which correlates with a reduction in food intake and weight loss. Furthermore, subjecting mice to acute starvation, which prevents the production of leptin, was found to delay the onset and reduce the severity of disease.
