Researchers at the University of Texas Medical School in Houston say they have found evidence that pre-eclampsia my be an autoimmune disease.  Scientists were able to induce symptoms similar to pre-eclampsia in pregnant mice by administering auto-antibodies that were isolated from women suffering from pre-eclampsia.

In animals at least, the researchers were able to prevent preeclampsia in pregnant mice leading to excitement that a treatment may be possible for humans.
