Peter S. Heeger, MD, is Professor of Medicine, Director of Transplant Research and a member of the Immunology Institute and the Recanati Miller Transplant Institute at the Icahn School of Medicine at Mount Sinai in New York. He leads the Clinical Trials in Organ Transplantation consortium, conducting trials to assess the utility of noninvasive biomarkers to predict outcomes in transplant recipients. His basic research interests are mechanisms of allograft injury and tolerance, with a focus on complement and T lymphocytes. He serves as current chair of the TTT NIH study section, is an active member of the American Society of Transplantation, and has authored >130 publications in the field.

I lead a basic science lab in transplant immunology and complement/T cell interactions. I am also the Director of Transplant Research at Mount Sinai and oversee all clinical and translational transplant trials at the institution. Our group leads a multicenter international NIH trial on biomarkers as predictors of transplant outcome
Summary of Research Studies:
The research performed in my laboratory focuses on understanding the cellular and molecular immunologic events involved in rejection and tolerance of allogeneic organ grafts in mouse models and in humans. Using mouse models we assess a) how and where alloreactive T cell recognize antigens found in transplanted donor tissues and b) which induced effector mechanisms are essential for inducing graft pathology. Recently published work from our group has also delineated a new link between innate and adaptive immunity by demonstrating that alternative pathway complement components influence the strength of all T cell immune responses, including those directed at allogeneic tissues. Lessons derived from the animal studies are being ''translated'' into humans. I direct an NIH U01 multicenter trial to assess the utility of noninvasive markers to predict outcome in organ transplant recipients. The study is designed to provide a rational scientific foundation for therapeutic decision-making aimed at maximizing graft survival and minimizing toxicity in organ graft recipients.
