Patients with myelodysplastic syndrome (MDS) have intrinsic, usually acquired genetic defects in their hematopoietic stem cells, but some others exhibit T-cell–mediated inhibition of hematopoiesis and good responses to immunosuppression. In these cases, MDS shares a similar pathophysiology with aplastic anemia (AA). Here, we review the evidence supporting a role of the immune system in the pathophysiology of MDS and the results of clinical trials of immunosuppressive agents.
