Why does a mother’s immune system not reject a fetus the same way it rejects a transplanted organ? The mechanism that allows for maternal-to-fetal tolerance is one of the key dysfunctional features in the pregnancy disorder preeclampsia. In preeclampsia, the mother’s blood pressure elevates to dangerously high levels leading to high risks for heart attack or stroke. The current treatment is bed rest and eventually delivery of the fetus to save the mother’s life. ImmunoVation LLC seeks to develop real treatments. Its founder Andrea Loewendorf obtained her Ph.D. in immunology from the University of Halle-Wittenberg, Germany, and has since performed immunology research at several universities and research institutes.
