Molecular switch discovered that could lead to anti-clotting drugs with less risk of bleeding

Researchers at the University of Illinois at Chicago have discovered a molecular switch that causes small, beneficial clots that stop bleeding to enlarge further during wound healing. By blocking this switch in lab mice, the researchers prevented small clots from growing -- a process that can pose a danger in humans -- while preserving their ability to staunch bleeding. Their findings, published online in Nature, open up the possibility for developing potent anti-clotting drugs that don't raise the risk of bleeding...
