Glycosaminoglyeans on hemostasis: Dermatan sulfate action on the fibrinolytic system
Dermatan sulfate (DS) is well-known for its anticoagulant activity by binding to heparin cofactor II in order to enhance the antithrombin action. It has also been suggested that DS has a profibrinolytic effect, although the exact molecular mechanism is unknown. This review exposes the results obtain...

Dermatan sulfate (DS) is well-known for its anticoagulant activity by binding to heparin cofactor II in order to enhance the antithrombin action.
