    Motixafortide and G-CSF To Mobilize Hematopoietic Stem Cells for Autologous Transplantation in Multiple Myeloma: A Randomized Phase III Trial

    This Phase III study was designed to compare the safety and efficacy of motixafortide + granulocyte colony-stimulating factor (G-CSF) versus placebo + G-CSF in patients with multiple myeloma undergoing hematopoietic stem progenitor cell mobilization before autologous hematopoietic stem cell transplantation.

    Obesity Induced Inflammation Exacerbates Clonal Hematopoiesis

    Investigators showed that obesity was highly associated with CHIP and that a pro-inflammatory state could potentiate the progression of CHIP to more significant hematologic neoplasia.

    Oncogenic Drivers Dictate Immune Control of Acute Myeloid Leukemia

    Researchers examined immune responses in genetically distinct models of AML and demonstrated that specific AML oncogenes dictate immunogenicity, the quality of immune response, and immune escape through immunoediting.

    M2 Macrophages Drive Leukemic Transformation by Imposing Resistance to Phagocytosis and Improving Mitochondrial Metabolism

    Scientists showed that AML-derived macrophages presented immunosuppressive and pro-leukemogenic functions, in part related to the acquisition of AML mutations.

    Co-Targeting BCL-XL and BCL-2 by PROTAC 753B Eliminates Leukemia Cells and Enhances Efficacy of Chemotherapy by Targeting Senescent Cells

    Investigators reported pre-clinical single-agent activity of 753B against different leukemia subsets. 753B effectively reduced cell viability and induced dose-dependent degradation of BCL-XL and BCL-2 in a subset of hematopoietic cell lines, AML primary samples, and in vivo PDX AML model.

    Reticulocytes in Donor Blood Units Enhance Red Blood Cell Alloimmunization

    Researchers tested whether reticulocytes in donor RBC units could enhance RBC alloimmunization. Using a murine model, they demonstrated that transfusing donor RBC units with increased reticulocyte frequencies dose-dependently increased RBC alloimmunization rates and alloantibody levels.

    Lectin-Based Carbohydrate Profile of Megakaryocytes in Murine Fetal Liver During Development

    Investigators characterized and quantified fetal megakaryocytic cells in mouse fetal liver according to their glycan residues at different gestational ages through lectins.

    Single-Cell Transcriptome Analysis Profiles the Expression Features of TMEM173 in BM Cells of High-Risk B-Cell Acute Lymphoblastic Leukemia

    Researchers provided insights into the transcriptomic features of TMEM173 in the bone marrow of high-risk B cell acute lymphoblastic leukemia (B-ALL) patients. Targeted activation of TMEM173 in specific cells might provided new therapeutic strategies for B-ALL patients.
