    Abstract

    Inserting EF1α-Driven CD7-Specific CAR at CD7 Locus Reduces Fratricide and Enhances Tumor Rejection

    Researchers developed a 2-in-1 strategy to insert EF1α-driven CD7-specific CAR at the disrupted CD7 locus and compared it to two other known strategies: one was random integration of CAR by a retrovirus and the other was site-specific integration at T cell receptor alpha constant locus.

    Abstract

    Rational Design of PD-1-CD28 Immunostimulatory Fusion Proteins for CAR T Cell Therapy

    Investigators compared different PD-1-CD28 immunostimulatory fusion protein variants in a human leukemia model to assess the impact of distinctive design choices on CAR T cell performance in vitro and a xenograft mouse model.

    Donor-Derived CAR-T Therapy Improves the Survival of Relapsed B-ALL after Allogeneic Transplantation Compared with Donor Lymphocyte Infusion

    Researchers conducted a single-center, retrospective comparative study that consisted of 12 patients who were treated with donor lymphocyte infusion and 12 patients treated with donor-derived CD19 CAR-T cells with three overlaps.

    Abstract

    Efficacy of Redox Nanoparticles for Improving Survival of Transplanted Cells in a Mouse Model of Ischemic Stroke

    Investigators tested the protective efficacy of these redox nanoparticles in cell culture and a mouse model of ischemic stroke. Induced human dental pulp stem cells were subjected to oxygen–glucose deprivation and reoxygenation to recapitulate ischemia and reperfusion in the penumbra surrounding a cerebral infarct.

    Abstract

    A Novel TREM1/DAP12-Based Multiple Chain CAR-T Cell Targets PTK7 in Ovarian Cancer Therapy

    Scientists developed and evaluated the efficacy of novel CAR-T cells targeting PTK7 through TREM1/DAP12 signaling against ovarian cancer. The expression of PTK7 in ovarian cancer tissues and cells was evaluated using immunohistochemical staining and flow cytometric analysis.
