Research Interests
  • Immunology - Role of dendritic cells in peripheral tolerance and transplantation. Use of dendritic cells that have interacted with donor apoptotic cells or exosomes to prolong graft survival. Galectin-1. Human skin dendritic cells.
  • Gene Therapy - Generation of recombinant viral vectors encoding immuno-regulatory molecules to prolong graft survival. Effect of recombinant viral vectors on dendritic cells.

The main work of our laboratory is to investigate the function of professional Ag-presenting cells, in particular dendritic cells of the immune system, during transplant rejection and transplant tolerance / immune-suppression. The better understanding of the role of dendritic cells in transplantation could lead to the development of novel dendritic cell-based therapies to promote donor-specific tolerance/immune-suppression in transplant recipients, one of the final goals in transplantation.
