Title:  
Restoring immunocompetence after allogeneic stem cell transplantation and graft-versus-host disease 


Abstract:

The goal of our lab is to understand how naïve T-cells are regenerated following T-cell depletion in order to improve their recovery and later increase the efficacy of immunotherapy. Guided by a bedside-to-bench approach to research, we build upon our clinical expertise to develop murine models that recreate human conditions. Based on these models, we hope to improve our basic understanding of fundamental processes that interfere with and regulate naïve CD4+ T-cell regeneration in the setting of human lymphopenia.  Studies in the Guimond laboratory focus on

two primary projects: 

I. The biology and therapy of T-cell depletion, and 

II. The immunobiology and immunotherapy of acute graft-versus-host disease (aGVHD)


For several leukemia patients, allogeneic stem cell transplantation (allogeneic-SCT) is the unique therapeutic modality that could potentially cure their disease. Despite significant progress made in clinical management of allogeneic-SCT, aGVHD and infectious complications remain the second and third cause of mortality after disease recurrence. Clinical options to restore immunocompetence after allogeneic-SCT are very limited because of the risk to worsen graft-versus-host disease (GVHD).  It is well known that the adverse effects of GVHD greatly exaggerates the immunosuppression normally associated with Hematopoietic Stem Cell Transplantation. During this presentation, we will discuss about the adverse effect of GVHD on the CD4 and CD8 peripheral niche with a focus on future therapies to improve immunocompetence in transplanted patients.
