Prevention of acute graft-versus-host-disease by selective depletion of T cells reactive with minor histocompatibility antigens on epithelial cells.
Graft-versus-host disease (GVHD) is a major obstacle in allogeneic hematopoietic stem cell transplantation (HSCT). Mature donor T-cells present in the graft play a pivotal role in the development of acute GVHD. On the other hand, mature donor T-cells in the graft are also crucial for the elimination of residual tumor cells still present in the patient after HSCT. Whether donor T cells act non-specifically against the patient, including an overlapping GVHD/GVL reactivity, or some donor T cells have GVHD reactivity while other donor T cells have GVL reactivity is still unclear. Some in-vitro data are suggestive that selective T cell depletion techniques are possible by which GVHD-reactive T cells can be eliminated while GVL-reactive T cells are preserved. Here we update some approaches of selective T cell depletion that have been developed in our laboratory.
