BLOOD COMMENTARIES

Lee and colleagues investigated the role of the intestinal microbiota in steady-state hematopoieisis, demonstrating that microbiota-derived DNA circulates to the bone marrow, where uptake by mononuclear cells leads to inflammatory cytokine production favoring myeloid-cell maturation of hematopoietic progenitors.

REVIEW ARTICLE

Filamins are scaffold proteins for signaling proteins and adhesion molecules, and mutations in filamin A (FLNa) cause a wide range of defects in the brain, cardiovascular system, gastrointestinal tract, and skeleton, as well as in megakaryocytes. Rosa and colleagues review the important role of FLNa in platelet development and its critical importance to proplatelet production by megakaryocytes.

CLINICAL TRIALS AND OBSERVATIONS

In this month's CME article, an analysis of over 1300 patients with diffuse large B-cell lymphoma (DLBCL), Wang et al demonstrate that the approximately 13% of patients with concurrent indolent lymphoma at diagnosis had the same prognosis as those patients with isolated DLBCL.

GENE THERAPY

HEMATOPOIESIS AND STEM CELLS

Lee and colleagues investigated the role of the intestinal microbiota in steady-state hematopoieisis, demonstrating that microbiota-derived DNA circulates to the bone marrow, where uptake by mononuclear cells leads to inflammatory cytokine production favoring myeloid-cell maturation of hematopoietic progenitors.

LYMPHOID NEOPLASIA

Gao et al report that early use of extracorporeal photopheresis improves time to next treatment and survival in patients with Sézary syndrome.

LETTERS TO BLOOD

Tanasi et al present a prospective strategy for identifying patients with Philadelphia-like acute lymphoblastic leukemia, demonstrating the efficacy of early introduction of tyrosine kinase inhibitors in improving outcomes.
