Abstract:Myeloid derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells that expand during many inflammatory conditions and malignancies. MDSCs may play an important role following allogeneic hematopoietic stem/progenitor cell transplant (HSCT). MDSCs suppress T-cell, B-cell and dendritic cell responses by a number of mechanisms, including promoting regulatory T cell expansion and producing soluble mediators such as Arginase 1 (Arg-1) and iNOS. MDSCs are divided into two subsets: mono… Show more
