High-dose dexamethasone corrects impaired myeloid-derived suppressor cell function via Ets1 in immune thrombocytopenia

Move over Tregs, MDSCs are here

In this issue of Blood, Hou et al show the involvement of myeloid-derived suppressor cells (MDSCs) in the pathogenesis of immune thrombocytopenia (ITP) and identify a novel mechanism by which high-dose dexamethasone (HD-DXM) promotes MDSC expansion and function and correlates with increased platelet counts.
