    Single-Cell Imaging of T Cell Immunotherapy Responses In Vivo

    Optically clear immunocompromised zebrafish were engrafted with fluorescent-labeled human cancers along with CAR T cells, bispecific T cell engagers, and antibody peptide epitope conjugates, allowing real-time single-cell visualization of T cell–based immunotherapies in vivo.

    Selective Deletion of Human Leukocyte Antigens Protects Stem Cell-Derived Islets from Immune Rejection

    Scientists used genetic engineering to create human pluripotent stem cells in which the majority of the polymorphic human leukocyte antigens, the main drivers of allogeneic rejection, were deleted.

    Transcriptional Profiling of Circulating Mononuclear Cells from Patients with Chronic Obstructive Pulmonary Disease Receiving Mesenchymal Stromal Cell Infusions

    Allogeneic, bone marrow-derived mesenchymal stem cells were systemically administered into patients with stable chronic obstructive pulmonary disease. Gene expression profiles from peripheral blood mononuclear cells were analyzed across the first week after infusion.

    CD7-Deleted Hematopoietic Stem Cells Can Restore Immunity after CAR T Cell Therapy

    To rescue T and NK cells after UCART7, researchers created hematopoietic stem cells (HSCs) genetically deleted for CD7. CD7-KO HSCs were able to engraft immunodeficient mice and differentiate into T and NK cells lacking CD7 expression.

    Lenvatinib Enhances T Cell Immunity and the Efficacy of Adoptive Chimeric Antigen Receptor-Modified T Cells by Decreasing Myeloid-Derived Suppressor Cells in Cancer

    The antitumour activity of lenvatinib in immunocompetent and immunodeficient mice was compared to determine the role of T cell immunity. The antitumour activity of T cells was analysed by cytokine production and adoptive T cell therapy.

    Pharmacological Inhibition of p38 MAPK Rejuvenates Bone Marrow Derived-Mesenchymal Stromal Cells and Boosts their Hematopoietic Stem Cell-Supportive Ability

    Researchers found that the ex vivo expanded mesenchymal stem cells showed activated p38 mitogen-activated protein kinase p38 (MAPK) signaling and exhibited increased oxidative stress.

    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 plus 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.

    The Promise(s) of Mesenchymal Stem Cell Therapy in Averting Preclinical Diabetes: Lessons from In Vivo and In Vitro Model Systems

    Investigators showed that intramuscular injection of placental (P)-MSCs homed more towards the visceral site, restored HOMA-IR and glucose homeostasis in the WNIN/GR-Ob rats. P-MSC therapy was effective in re-establishing the dysregulated cytokines.

    Donor-Derived M2 Macrophages Attenuate GVHD after Allogeneic Hematopoietic Stem Cell Transplantation

    Graft-versus-host disease (GVHD) was induced in lethally irradiated BALB/c mice. M2 macrophages derived from donor bone marrow (BM) were administered intravenously, while controls received donor BM-mononuclear cells and splenocytes.

    Cancer Stem Cell-Targeted Chimeric Antigen Receptor (CAR)-T Cell Therapy: Challenges and Prospects

    CAR-T cell therapy has shown more efficiency in cancer treatment, particularly regarding blood cancers. The expression of specific markers such as TAAs on CSCs in varied cancer types makes them as potent tools for CAR-T cell therapy.

    Putting Function Back in Dysfunction: Endothelial Diseases and Current Therapies in Hematopoietic Stem Cell Transplantation and Cellular Therapies

    Scientists summarize the current knowledge about statins and other agents used as endothelial protectants. They propose further studies using statins for prophylaxis and prevention of end-organ damage related to extensive endothelial dysfunction in hematopoietic stem cell transplantation and chimeric antigen receptor-T cells.

    Abstract

    Cardiac Complications Associated with Hematopoietic Stem-Cell Transplantation

    The association between hematopoietic stem-cell transplantation and early- and late-onset cardiotoxicity remains controversial as these cardiac complications, including acute heart failure and arrhythmia, such as atrial fibrillation, can occasionally be lethal.
