These attributes were assessed by a matrix of cell-surface and functional biological assays and included CAR-T cell viability, T cell subtype, cell proliferation, retention of radionuclide, chemotaxis, granzyme B, T cell exhaustion, intracellular IFN-gamma expression and specific cell killing of IL-13Rα2 positive target tumor cells. Here, IL13RA2 is linked to neoplasm.
