Research activities are focused on the biology of the complement system. Complement is a group of over 30 soluble and cell surface proteins that represent a crucial component of immune system. The laboratory is involved in the following areas of study
1. INFLAMMATION AND ALLOIMMUNITY: We are investigating the role of complement in inflammation and mechanisms of injury in various disease conditions, including hepatic and cardiac ischemia reperfusion injury, stroke and spinal cord injury. We are also working in the field or organ transplantation with a focus on complement-dependent inflammatory mechanisms, and how inflammation can shape an alloimmune response. A concurrent interest in the laboratory is the development of complement therapeutics, in particular complement inhibitors that can be targeted to sites of injury and disease.
2. CANCER: Complement plays an important role in both the induction and effector phases of an immune response to cancer. Immunity may be naturally induced or may be the result of passive or active immunotherapies. We are studying the role of complement in tumor immunity and investigating strategies to enhance a normally ineffective immune response to tumor cells. To this end, we are investigating mechanisms by which complement activation products and inflammation modulate both humoral and T cell responses to tumors.
