PG - 1151-6 LID - 10.3324/haematol.2008.001735 [doi] AB - Mesenchymal stem cells emerged as a promising treatment modality for steroid-refractory graft-versus-host disease, which represents a major complication of allogeneic hematopoietic stem cell transplantation. Dendritic cells (DCs) display an extraordinary capacity to induce T-cell responses and play a crucial role in the pathogenesis of graft-versus-host disease. Here, we investigated the impact of mesenchymal stem cells on the proinflammatory capacity of 6-sulfo LacNAc (slan) dendritic cells, representing a major subpopulation of human blood dendritic cells. Mesenchymal stem cells markedly impair maturation of slanDCs and their ability to secrete proinflammatory cytokines, which was dependent on prostaglandin E(2). In contrast, the release of anti-inflammatory IL-10 was improved by mesenchymal stem cells. Furthermore, mesenchymal stem cells efficiently inhibit slanDC-induced proliferation of CD4(+) and CD8(+) T cells and polarization of naive CD4(+) T lymphocytes into Th1 cells. These results indicate that mesenchymal stem cells significantly impair the high proinflammatory capacity of slanDCs and further substantiate their potential for the treatment of graft-versus-host disease.
