    Control of the Activity of CAR-T Cells within Tumors via Focused Ultrasound

    In mice with subcutaneous tumors, locally injected T cells with the inducible CAR and activated via focused ultrasound guided by magnetic resonance imaging mitigated on-target off-tumor activity and enhanced the suppression of tumor growth, compared with the performance of non-inducible CAR-T cells.

    Abstract

    Comprehensive RNA Editome Reveals That Edited Azin1 Partners with DDX1 to Enable Hematopoietic Stem Cell Differentiation

    Researchers sorted 12 murine adult hematopoietic cell populations at different stages and identified 30,796 editing sites through RNA sequencing. While the dynamic landscape of the RNA editome comprised of stage/group-specific and stable editing patterns, but it also underwent significant changes during lineage commitment.

    Abstract

    Human T Cells Engineered with a Leukemia Lipid-Specific TCR Enables Donor-Unrestricted Recognition of CD1c-Expressing Leukemia

    Scientists showed that human T cells engineered to express an methyl-lysophosphatidic acid (mLPA)-specific TCR, targeted diverse CD1c-expressing leukemia blasts in vitro and significantly delayed the progression of three models of leukemia xenograft in NSG mice, an effect that was boosted by mLPA-cellular immunization.

    Targeting of IL-10R on Acute Myeloid Leukemia Blasts with Chimeric Antigen Receptor-Expressing T Cells

    Researchers found that interleukin-10 receptor (IL-10R) was overexpressed in most acute myeloid leukemia cells, and played an important role in promoting the stemness of leukemia cells.

    Mesenchymal Stem Cell and Endothelial Progenitor Cells Coinjection Improves LPS-Induced Lung Injury via Tie2 Activation and Downregulation of the TLR4/MyD88 Pathway

    Coinjections of endothelial progenitor cells + mesenchymal stem cells significantly enhanced the survival rate of lipopolysaccharide-induced mice, decreased concentrations of pro-inflammatory cytokines, and increased the level of anti-inflammatory cytokine.

    Abstract

    Thrombopoietin-Based CAR-T Cells Demonstrate In Vitro and In Vivo Cytotoxicity to MPL Positive Acute Myelogenous Leukemia and Hematopoietic Stem Cells

    CAR T cells were designed using a ligand binding domain instead of a single chain variable fragments to target stem-like leukemia cells. Thrombopoietin, the natural ligand to the myeloproliferative leukemia protein (MPL) receptor, was used as the antigen binding domain to engage MPL expressed on hematopoietic stem cells and erythropoietic and megakaryocytic acute myeloid leukemias.
