    Chemical priming enhances the migratory and cytotoxic functions of mesothelin-targeting CAR-NK-92 cells against solid tumors.

  • 2

    Primed CAR-NK cells exhibited increased CCR7 expression, improved tumor-directed migration, and enhanced cytotoxic kinetics.

  • 3

    Chemical priming led to increased perforin accumulation and IFN-γ production in CAR-NK cells without compromising cell viability.

  • 4

    In vivo studies demonstrated that primed CAR-NK cells achieved superior tumor control and increased intratumoral infiltration.

  • 5

    The study suggests that chemical priming is a promising non-genetic strategy to improve CAR-NK cell activity against solid tumors.
