Dr. Leonardo Riella is an Assistant Professor of Medicine at Harvard Medical School and the Assistant Medical Director of Kidney and Pancreas Transplantation at Brigham and Women’s Hospital. Dr Riella’s primary research interests are to:- Develop new diagnostic tests that could detect earlier graft dysfunction and rejection (even before creatinine elevation)- Promote transplant tolerance by the development of novel drugs to promote regulation and prevent/treat antibody-mediated rejection (major cause of kidney loss after transplant)- Implement novel blood assays that would permit to measure the immune system function. This would allow more precise adjustment of dosages of immunosuppressive drugs, minimizing risks of over-mmunosuppression that may lead to infections/cancers.

Specifically, Dr. Riella is currently exploring the role of the Notch pathway in T and B cell activation/differentiation in alloimmunity; developing novel assays to characterize alloantibodies; and investigating the coinhibitory pathways that suppress T cell activation and promote tolerance, such as the PD1/PDL-1 pathway. He is also involved in translational/mechanistic clinical trials that are attempting to identify earlier markers of rejection and develop novel assays to measure the immune function in kidney transplant recipients.
