Acute graft-versus-host disease (GVHD) is a major cause of morbidity and mortality in patients undergoing allogeneic bone marrow transplantation (BMT) for the treatment of leukemia and other immunogenetic disorders. The use of tolerogenic dendritic cells (DCs) that induce the generation/activation of regulatory T (Tr) cells for the treatment of acute GVHD following allogeneic BMT has been recently established. Therefore, the identification of factors that contribute to the development of tolerogenic DCs is highly relevant. We report on the use of the known immunosuppressive neuropeptide, the vasoactive intestinal peptide (VIP), as a new approach to induce tolerogenic DCs with the capacity to prevent acute GVHD. DCs differentiated in the presence of VIP impair allogeneic haplotype-specific responses of donor CD4+ cells in mice given transplants by inducing the generation of Tr cells in the graft. VIP-induced tolerogenic DCs did not abrogate the graft-versus-leukemia response presumably by not affecting the cytotoxicity of transplanted T cells against the leukemic cells. Therefore, the inclusion of VIP-induced tolerogenic DCs in future therapeutic regimens may minimize the dependence on nonspecific immunosuppressive drugs used currently as antirejection therapy, and facilitate the successful transplantation from mismatched donors, by reducing the deleterious consequences of acute GVHD and extending the applicability of BMT.
