About Research

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.
