    Base-Edited CAR7 T Cells for Relapsed T Cell Acute Lymphoblastic Leukemia

    The authors used base editing to generate universal, off-the-shelf CAR T cells. Healthy volunteer donor T cells were transduced with the use of a lentivirus to express a CAR with specificity for CD7, a protein that is expressed in T cell acute lymphoblastic leukemia

    Abstract

    c-Kit Signaling Potentiates CAR T Cell Efficacy in Solid Tumors by CD28- and IL-2-Independent Co-Stimulation

    Researchers used a well-studied mutant c-KIT protein as a co-stimulatory domain to generate CAR T cells with strong IFNγ signaling that were able to overcome the immunosuppressive microenvironment of solid tumors.

    AbstractGraphical Abstract

    Nanovesicles Loaded with a TGF-β Receptor 1 Inhibitor Overcome Immune Resistance to Potentiate Cancer Immunotherapy

    Investigators identified that inhibition of transforming growth factor-β (TGF-β) receptor 1 could relieve tumor fibrosis, thus facilitating the recruitment of tumor-infiltrating T lymphocytes.

    Abstract

    Fate and Efficacy of Engineered Allogeneic Stem Cells Targeting Cell Death and Proliferation Pathways in Primary and Brain Metastatic Lung Cancer

    Researchers created and characterized diagnostic and therapeutic stem cells, expressing epidermal growth factor receptor (EGFR)-targeted nanobody fused to the extracellular domain of death DR4/5 ligand that simultaneously targeted EGFR and DR4/5, in non-small cell lung cancer tumor models.

    Complete Remission of Diabetes with a Transient HDAC Inhibitor and Insulin in Streptozotocin Mice

    The authors showed that eliminating abnormal bone marrow-derived cells using bone marrow transplantation resulted in controlling serum glucose in diabetic mice, in which normoglycemia was sustained even after cessation of insulin therapy.
