Research Interests

• Role of leukocyte-derived tissue factor in thrombosis
• Role of plasminogen activator inhibitor-1 (PAI-1) in the proliferative response to vascular injury
• Mechanisms by which C-reactive protein (CRP) modulates thrombosis
• Role of heme oxygenase-1 in thrombosis
• Regulation of fibrinolysis by thrombin activatable fibrinolysis inhibitor (TAFI)

Techniques / Methodology:

• Mouse gene targeting
• Rodent models of human vascular disease
• Structure-function studies of blood coagulation proteins
• Thrombosis models

Research Description

Our research laboratory focuses on the roles of the blood coagulation and fibrinolytic systems in vascular disease. We are interested in the molecular processes that determine acute thrombus formation after vascular injury, as well as those that regulate subsequent thrombolysis. We also are interested in how components of the blood clotting and fibrinolytic systems contribute to the pathogenesis of chronic vascular disorders, such as atherosclerosis and restenosis after percutaneous coronary interventions. We study these issues by a variety of experimental approaches, ranging from in vitro studies with purified proteins to intact animal studies. In particular, we rely heavily on murine models of vascular injury and thrombosis, since they enable us to examine the impact of specific genes on complex biologic processes within the living animal. We also are conducting human genetic studies. These projects address the role of plasminogin activator inhibitor-1 as a risk factor for myocardial infarction, and the molecular basis of the variable sensitivity of patients to anticoagulation with warfarin.
