Study: Fat Cells Protect Against Infections

Not all fat is bad. A new study has found that fat cells that lie beneath the skin’s surface may protect against bacterial infections. U.S. researchers say dermal fat cells, known as adipocytes, produce peptides or proteins that shield against invading bacteria. Experts explain adipocytes provide immediate defense against bacteria by producing antimicrobials, giving immune system white cells time to reach a wound site. A common skin infection is caused by Staphylococcus...
