    Minimally Invasive Delivery of Therapeutic Agents by Hydrogel Injection into the Pericardial Cavity for Cardiac Repair

    In rodent models of myocardial infarction, investigators demonstrated that intrapericardial injection was an effective and safe method to deliver hydrogels containing induced pluripotent stem cells-derived cardiac progenitor cells or mesenchymal stem cells-derived exosomes.

    Identification of CD318, TSPAN8 and CD66c as Target Candidates for CAR T Cell Based Immunotherapy of Pancreatic Adenocarcinoma

    Researchers combined an empiric antibody-based flow cytometry screen with a cyclic immunofluorescence imaging platform and a comprehensive bioinformatical and experimental evaluation for off-tumor expression to identify pancreatic ductal adenocarcinoma-specific cell surface markers.

    GSDME-Mediated Pyroptosis Promotes Inflammation and Fibrosis in Obstructive Nephropathy

    Using bone marrow transplantation and cell type-specific Casp3 knockout mice, scientists demonstrated that Casp3/GSDME-mediated pyroptosis in renal parenchymal cells, but not in hematopoietic cells, played predominant roles in this process.

    Abstract

    Pre-Conditioning Modifies the Tumor Microenvironment to Enhance Solid Tumor CAR T Cell Efficacy and Endogenous Protective Immunity

    Using a novel human prostate stem cell antigen (PSCA) knock-in immunocompetent mouse model, researchers evaluated safety and therapeutic efficacy of PSCA-CAR T cells.

    Genome Editing of Donor-Derived T-Cells to Generate Allogenic Chimeric Antigen Receptor-Modified T Cells: Optimizing αβ T Cell-Depleted Haploidentical Hematopoietic Stem Cell Transplantation

    Using genome editing with Cas9 ribonucleoprotein and adeno-associated virus serotype 6, the authors integrated a CD19-specific chimeric antigen receptor in-frame into the TRAC locus.

    Robust Anti-Tumor Activity and Low Cytokine Production by Novel Humanized Anti-CD19 Car-T Cells

    Investigators designed a novel humanized anti-CD19 CAR-T cells by humanizing the framework region of scFv derived from a murine FMC63 mAb and combining it with CD8a transmembrane domain, 4-1BB costimulatory domain and CD3ζ signaling domain.

    Abstract

    High Proportion of Terminally Differentiated Regulatory T Cells after Allogeneic Hematopoietic Stem Cell Transplantation

    Scientists compared the frequencies of different regulatory T cell subtypes in healthy controls as well as in allogeneic hematopoietic cell transplantation patients with or without chronic graft-versus-host disease.

    Abstract

    A Single-Chain Antibody Generation System Yielding Car-T Cells with Superior Antitumor Function

    Researchers established a single-chain antibody (scFv) generation system in which scFv library-expressing CAR-T cells can be screened appropriately based on their antitumor functions.

    Age-Related Changes in the Inflammatory Status of Human Mesenchymal Stem Cells: Implications for Cell Therapy

    Scientists surveyed the literature to explore the intimate relationship between the inflammatory status of human mesenchymal stem/stromal cell (hMSCs) and their in vitro aging process. They posit that a shift from an anti-inflammatory to a pro-inflammatory phenotype of culture-expanded hMSCs contributes to a deterioration in their therapeutic efficacy.

    Contemporary Haploidentical Stem Cell Transplant Strategies in Children with Hematological Malignancies

    While comparing the outcomes of different haploidentical hematopoietic stem cell transplantation approaches, one must understand the transplant immunobiology and factors affecting the transplant outcomes.

    Abstract

    TCR-Like CARs and TCR-CARs Targeting Neoepitopes: An Emerging Potential

    The authors focus on the T cell receptor (TCR)-like CARs and TCR-CARs directed against tumor-derived epitopes, with a concerted view on neoepitopes.
