Platelets, Thrombosis and Cancer Research Lab

About the Laboratory

Thrombosis (blood clots) is the most common cause of death in the Western world as a result of stroke, myocardial infarction and venous thromboembolism. The Platelet Thrombosis and Cancer Research Laboratory studies the mechanisms of clot formation, the biology of platelets and coagulation proteins and how manipulation of these can be used to influence cardiovascular disease and cancer. We use real time intravital fluorescent microscopy and flow cytometry assays to investigate the processes of platelet accumulation and coagulation initiation in the mouse circulation. We use this insight to design projects that will translate biological insights into clinical disease with impact on patients with heart attack, stroke and cancer associated venous thrombosis in order to develop new diagnostics and drug therapies for the clots that cause heart attacks and strokes and deep vein thrombosis. Our particular focuses are: novel assays of coagulation and platelet function and a highly activated “procoagulant” platelets and the role that they play in health and disease.
