  • Immunology of leukemia and lymphoma: translational research;
  • Autologous and allogenous hematopoietic stem cell transplantation;
  • Manipulation of hematopoietic cell grafts: selective elimination of alloreactive T lymphocytes to prevent and treat graft-versus-host diseases;
  • Specific targeting of malignant cells, using photodynamic and immunological therapy approaches;
  • Study of action mechanisms and optimization of monoclonal antibody and immunoconjugates;
  • Growth and expansion factors of hematopoietic stem cells and blood progenitors.

The aim of our study is to use cellular and immunological approaches to fight such blood cancers as leukemia and lymphoma. Our research unit is examining different monoclonal antibodies and immunoconjugates as well as a photodynamic approach for eliminating cancerous and alloreactive cells.

We have developed particular expertise in translational research, enabling the transfer of basic discoveries to patients. Thanks to our studies, new hematological and immunological strategies have been identified and were implemented in early clinical studies (Phase 1 and 2). We are the principal investigator of a multicentric study (Canada and USA) to evaluate a new photodynamic treatment. 

We are also working on the expansion of hematopoietic stem cells and blood cell progenitors that will enable and accelerate hematological and immunological reconstitution following transplantation.
