    A Versatile CRISPR-Cas13d Platform for Multiplexed Transcriptomic Regulation and Metabolic Engineering in Primary Human T Cells

    The authors developed multiplexed effector guide arrays, a platform for programmable and scalable regulation of the T cell transcriptome using the RNA-guided, RNA-targeting activity of CRISPR-Cas13d.

    Cellular Uptake and In Vivo Distribution of Mesenchymal-Stem-Cell-Derived Extracellular Vesicles Are Protein Corona Dependent

    Scientists explored the impact of protein corona on extracellular vesicles (EVs) derived from two culturing conditions in which specific proteins acquired from media were simultaneously adsorbed on the EV surface.

    Inosine Induces Stemness Features in CAR-T Cells and Enhances Potency

    Investigators enhanced CAR-T cell potency by knocking out CD39, CD73, or adenosine receptor 2a but observed only modest effects. In contrast, overexpression of adenosine (Ado) deaminase, which metabolized Ado to inosine (INO), induced stemness and enhanced CAR-T functionality.

    Engineered T Cells Secreting Anti-BCMA T Cell Engagers Control Multiple Myeloma and Promote Immune Memory In Vivo

    Researchers undertook a comprehensive preclinical study comparing the therapeutic potential of T cells either expressing second-generation anti-B cell maturation antigen (BCMA) CARs or secreting BCMAxCD3 T cell engagers in a T cell–limiting experimental setting.

    Abstract

    Structure-Guided Engineering of Immunotherapies Targeting TRBC1 and TRBC2 in T Cell Malignancies

    The authors demonstrated specificity redirection by rational design using structure-guided computational biology to generate a TRBC2-specific antibody.

    Targeting the Mevalonate or Wnt Pathways to Overcome CAR T-Cell Resistance in TP53-Mutant AML Cells

    The authors showed that CAR T-cells engaging TP53-deficient leukemia cells exhibited a prolonged interaction time, upregulated exhaustion markers, and were inefficient to control acute myeloid leukemia (AML) cell outgrowth in vitro and in vivo compared to TP53 wild-type cells.

    Abstract

    Tough Physically Crosslinked Poly(vinyl Alcohol)-Based Hydrogels Loaded with Collagen Type I to Promote Bone Regeneration In Vitro and In Vivo

    Investigators developed a tough poly(vinyl alcohol) (PVA)-based hydrogel using a facile physical crosslinking method, comprising of PVA, tannic acid, and hydroxyapatite.

    Gene Therapy in Glioblastoma Multiforme: Can It Be a Role Changer?

    Gene therapy, a relatively nascent advanced approach, holds promise as a potential treatment for cancer, particularly glioblastoma multiforme. It possesses the potential to address the limitations of previous treatments and even newer advanced therapies like mAbs, owing to its distinct properties.
