    Distinct
    Developmental Pathways from Blood Monocytes Generate Human Lung Macrophage Diversity

    Intravascular cell labeling, cell transplantation, and fate-mapping studies established that classical CD14+ blood monocytes derived from hematopoietic stem and progenitor cells migrated into lung tissue and gave rise to human interstitial and alveolar macrophages.

    CXCR5
    CAR-T Cells Simultaneously Target B Cell Non-Hodgkin’s Lymphoma and Tumor-Supportive Follicular T Helper Cells

    To target both B cell Non-Hodgkin’s lymphoma and follicular T helper cells in the tumor microenvironment, researchers applied a chimeric antigen receptor that recognized human CXCR5 with high avidity.

    Identification
    of a Subset of Immunosuppressive P2RX1-Negative Neutrophils in Pancreatic Cancer Liver Metastasis

    RNA sequencing of murine pancreatic ductal adenocarcinoma liver metastasis-infiltrated neutrophils show that P2RX1-deficient neutrophils express increased levels of immunosuppressive molecules, including PD-L1, and have enhanced mitochondrial metabolism.

    CRISPR/Cas9
    Directed to the Ube3a Antisense Transcript Improves Angelman Syndrome Phenotype in Mice

    Scientists showed that gene editing of Ube3a-ATS in the mouse brain resulted in the formation of base pair insertions/deletions in neurons and the subsequent unsilencing of the paternal Ube3a allele in neurons, which partially corrected the behavior phenotype of a murine Angelman syndrome model.

    U2af1 Is Required for Survival and Function of Hematopoietic Stem/Progenitor Cells

    Using a novel conditional U2af1 knockout allele, investigators found that deletion of U2af1 results in profound defects in hematopoiesis characterized by pancytopenia, ablation of hematopoietic stem/progenitor cells leading to bone marrow failure and early lethality in mice.

    A Modular and Controllable T Cell Therapy Platform for Acute Myeloid Leukemia

    Researchers developed a modular and controllable MHC-unrestricted adoptive T cell therapy platform tailored to acute myeloid leukemia.

    Platelet-Targeted
    Gene Therapy Induces Robust Immune Tolerance Even in a Primed Model via Peripheral Clonal Deletion of Antigen-Specific CD4 and CD8 T Cells and Expansion of Antigen-Specific Regulatory T Cells

    Using the OT-I/WT model, the authors showed that antigen-specific CD8 T cells were partially deleted in recipients after platelet-targeted gene transfer.

    Zfp521
    Is Essential for the Quiescence and Maintenance of Adult Hematopoietic Stem Cells under Stress

    Scientists found that Zinc finger protein 521 (Zfp521) deletion did not inhibit adult hematopoiesis under homeostatic conditions. In contrast, Zfp521-null chimeric mice showed significantly reduced pool size of hematopoietic stem cells and hematopoietic progenitor cells associated with increased apoptosis and loss of quiescence.

    Target Epitope Masking Resistance that Can Occur on Low-Antigen-Expresser AML Blasts after IL-1RAP Chimeric Antigen Receptor T Cell Therapy Using the Inducible Caspase 9 Suicide Gene Safety Switch

    As acute myeloid leukemia (AML) primary blasts express different levels of accessory protein of the interleukin-1 receptor (IL-1RAP), scientists modeled transduction of different AML tumor cell lines screened for density of antigenic sites with their lentiviral vectors carrying a third-generation IL-1RAP chimeric antigen receptor, an iCASP9 suicide gene, and a truncated CD19 surface gene.
