    GM-CSF Receptor Expression Determines Opposing Innate Memory Phenotypes at Different Stages of Myelopoiesis

    Researchers showed that GM-CSF programmmed myeloid committed progenitors to produce trained macrophages but programmed the upstream non-committed LKS+ progenitors to produce tolerized macrophages.

    Abstract

    Formation of Recurring Transient Ca2+-Based Intercellular Communities during Drosophila Hematopoiesis

    The authors revealed that tissue scale signaling regulation could arise from local gap-junction mediated cell–cell signaling through the spatiotemporal establishment of an intermediate-scale of transient multicellular communication communities over the course of tissue development.

    McPh1, Mutated in Primary Microcephaly, Is Also Crucial for Erythropoiesis

    Scientists revealed that microcephalin (Mcph1)-knockout mice exhibited congenital macrocytic anemia due to impaired terminal erythroid differentiation during fetal development.

    Small-Molecule α-Lipoic Acid Targets ELK1 to Balance Human Neutrophil and Erythrocyte Differentiation

    In vitro culture of isolated CD34+, common myeloid progenitors, and CD34+ CD371– hematopoietic stem progenitor cells were performed to assay the differentiation potential of monocytes, neutrophils, and erythrocytes.

    Regulation of Erythroid Differentiation via the HIF1α-NFIL3-PIM1 Signaling Axis under Hypoxia

    Scientists studied the effect and mechanism of hypoxia on erythroid differentiation of K562 cells and observed the effect of hypoxia on early erythropoiesis of zebrafish.

    Abstract

    Survivors of Polymicrobial Sepsis Are Refractory to G-CSF-Induced Emergency Myelopoiesis and Hematopoietic Stem and Progenitor Cell Mobilization

    Researchers treated recovered sham and cecal ligation and puncture mice with a mobilizing regimen of granulocyte colony-stimulating factor (G-CSF) at day 20 post-surgery.

    Abstract

    Immunoglobulin Replacement vs Prophylactic Antibiotics for Hypogammaglobulinemia Secondary to Hematological Malignancy

    In this randomized controlled feasibility trial conducted in seven hospitals in Australia and New Zealand, scientists enrolled patients with secondary hypogammaglobulinemia with either a history of recurrent/severe infection or an immunoglobulin G level less than 4 g/L.
