Figure 5. IL13 mutein-CAR T cells kill IL13Rα1- and IL13Rα2-positive cells.
(A,B) IL13 mutein-CAR T cells (IL13Y-CAR, IL13K-CAR) killed Raji-IL13Rα1and Raji-IL13Rα2 cells in contrast to Raji and Raji-GFP cells in a standard 4h cytotoxicity assay. Controls (NT T cells or mhFAP-CAR T cells) exhibited no cytolytic activity (results for 2 donors are shown).
