    Selective Refueling of CAR T Cells Using ADA1 and CD26 Boosts Antitumor Immunity

    Scientists presented a metabolic refueling approach using inosine as an alternative fuel. CAR T cells were engineered to express membrane-bound CD26 and cytoplasmic adenosine deaminase 1 (ADA1), converting adenosine to inosine.

    Controlling CAR T Cell Activity and Specificity with Synthetic SparX Adapters

    Researchers developed a controllable cell therapy where synthetic D-Domain-containing proteins (SparX) bind one or more tumor antigens and mark those cells for elimination by genetically modified T cells

    Live-Attenuated Virus Vaccine Defective in RNAi Suppression Induces Rapid Protection in Neonatal and Adult Mice Lacking Mature B and T Cells

    The mosquito-transmitted Nodamura virus was attenuated in mice by mutations that prevent expression of the B2 viral suppressor of RNA interference and consequently, drastically enhance in vivo production of the virus-targeting small-interfering RNAs.

    Efficient CAR T Cell Targeting of the CA125 Extracellular Repeat Domain of MUC16

    Researchers tested a series of antibodies raised against the CA125 extracellular repeat domain of MUC16 and adapted them to the CAR format. Comparisons between these candidates, and against an existing CAR targeting the MUC16 ectodomain, identified K101 as having high potency and specificity.

    Abstract

    CD3 Aptamers Promote Expansion and Persistence of Tumor-Reactive T Cells for Adoptive T Cell Therapy in Cancer

    To identify CD3-specific T cell agonists, several RNA aptamers were selected against CD3 using SELEX combined with high-throughput sequencing.

    Design of a Stem Cell–Based Therapy for Ependymal Repair in Hydrocephalus Associated with Germinal Matrix Hemorrhages

    Investigators explored the possibilities of ependymal repair in germinal matrix hemorrhages/posthemorrhagic hydrocephalus using a combination of neural stem cells, ependymal progenitors, and mesenchymal stem cells.

    Comparative Performance of scFv-Based Anti-BCMA CAR Formats for Improved T Cell Therapy in Multiple Myeloma

    CD8TM.41BBIC-based anti-B cell maturation antigen CAR vectors with either a long linker or a short linker between the light and heavy scFv chain, CD28TM.41BBIC-based and CD28TM.CD28IC-based anti-BCMA CAR vector systems were used in primary human T cells.

    Abstract

    Network Meta-Analysis of CAR T-Cell Therapy for the Treatment of 3L+ R/R LBCL After Using Published Comparative Studies

    Scientists highlight important differences in clinical outcomes between CAR T-cell therapies. Axi-cel demonstrated improved overall survival compared to tisa-cel and liso-cel, and both axi-cel and liso-cel showed higher response rates compared to tisa-cel.
