Clues discovered on preeclampsia

But new research suggests the secret may lie in the body's own immune cells.

A University of Mississippi team found a variety of immune cells that gets altered as preeclampsia develops.

But removing those altered cells in lab animals cut high blood pressure and allowed a fetus to grow normally, two major effects of preeclampsia.

Right now, the only solution is early delivery.
