    Engineering T Cells to Suppress Acute GvHD and Leukemia Relapse after Allogeneic Hematopoietic Stem Cell Transplantation

    The authors showed that OX40 was upregulated on T cells infiltrating graft-versus-host disease (GvHD) target organs in a rhesus macaque model, supporting the hypothesis that targeted ablation of OX40+ T cells will mitigate GvHD pathogenesis.

    Loss of AID Exacerbates the Malignant Progression of CLL

    Researchers generated an activation-induced cytidine deaminase (AID) knockout chronic lymphocytic leukemia (CLL) mouse model and found that these mice died significantly earlier than their AID-proficient counterparts.

    Specific Inhibition of the Transporter MRP4/ABCC4 Affects Multiple Signaling Pathways and Thrombus Formation in Human Platelets

    Transport assays in isolated membrane vesicles showed a concentrationdependent inhibition of multidrug resistance protein 4 (MRP4)-mediated transport of cyclic nucleotides, thromboxane B2 and fluorescein (FITC)- labeled sphingosine-1-phosphate by the selective MRP4 inhibitor Ceefourin-1.

    Retrospective Analysis of Somatic Mutations and Clonal Hematopoiesis in Astronauts

    Using deep, error-corrected, targeted DNA sequencing researchers assayed for somatic mutations in clonal hematopoiesis-driver genes in peripheral blood mononuclear cells isolated from de-identified blood samples collected from 14 astronauts who flew Shuttle missions between 1998–2001.

    Normalization of Cerebral Hemodynamics Following Hematopoietic Stem Cell Transplant in Children with Sickle Cell Disease

    Whole-brain cerebral blood flow and oxygen extraction fraction were measured by MRI one to three months before and 12-24 months after HSC transplant in ten children with sickle cell disease: three with prior overt strokes, five with prior silent strokes, and one with abnormal transcranial Doppler ultrasound velocities.

    Abstract

    Taz Protects Hematopoietic Stem Cells from an Aging-Dependent Decrease in PU.1 Activity

    The authors found that the Hippo pathway coactivator TAZ was potently induced in old HSCs and protected these cells from functional decline.

    Future Perspectives of Anemia Management in Chronic Kidney Disease Using Hypoxia-Inducible Factor-Prolyl Hydroxylase Inhibitors

    Hypoxia-inducible factor-prolyl hydroxylase inhibitors (HIF-PHIs) are novel agents to treat anemia in CKD. They stimulate endogenous erythropoietin production via HIF activation and thereby induce erythropoiesis.
