Dr. Jean-Sébastien Delisle is a hematologist and researcher who oversees the Cancer Immunology and Transplantation Research Unit. Dr. Delisle divides his time between his lab and his medical practice in hematology and hematopoietic stem cell transplantation. His research interests cover the entire spectrum from fundamental research to clinical applications in immunology and immunotherapy. Dr. Delisle is also an associate professor in the Faculty of Medicine at Université de Montréal.

Cancer Immunology and Transplantation

The biology of T lymphocytes and dendritic cells

T lymphocytes can have many functions. The signals that dictate the different stages of T lymphocyte differentiation are still poorly understood, and the ability to manipulate these signals for therapeutic purposes is an important issue. We focus on the roles of the cytokine TGF-β in memory T cell differentiation as well as the signals leading to T lymphocyte dysfunction in tumours (cosignalling) and in cultures to expand antigen-specific T cells. We are also studying the maturation of dendritic cells so that they can effectively present antigens to T cells.  

Adoptive immunotherapy in humans

Our laboratory is interested in the in-vitro expansion and differentiation of human T lymphocytes so that these cells can be used in clinical research protocols. In this area, we have adapted and developed cell culture systems to both increase the therapeutic potential of in-vitro educated T lymphocytes and study the fundamental biology of human T lymphocytes. Two adoptive immunotherapy protocols have been directly derived from the work in our lab and are currently being studied in patients.
