Targeting inflammation in lower-risk MDS.

ABSTRACT: The myelodysplastic syndromes (MDS) are a heterogeneous group of malignant hematopoietic stem cell disorders characterized by ineffective growth and differentiation of hematopoietic progenitors leading to peripheral blood cytopenias, dysplasia, and a variable risk of transformation to acute myelogenous leukemia. As most patients present with lower-risk disease, understanding the pathogenesis of ineffective hematopoiesis is important for developing therapies that will increase blood counts in patients with MDS. Various inflammatory cytokines are elevated in MDS and contribute to dysplastic differentiation. Inflammatory pathways mediated by interleukin (IL) 1b, IL-6, IL-1RAP, IL-8, and others lead to growth of aberrant MDS stem and progenitors while inhibiting healthy hematopoiesis. Spliceos
