Figure Lengend Snippet: In vitro generation of αCD19 CAR-T cells via FuNV CAR and selective cytotoxicity against CD19 + B Cells. ( a ) The schematic diagram ofαCD19 CAR-T cells generation through membrane fusion–mediated delivery of CAR proteins by FuNV CAR . ( b ) Flow cytometry histogram of surface CAR expression on T cells at indicated time points following co-incubation with FuNV CAR (n = 5 individual replicates). ( c ) The schematic diagram of the in vitro cytotoxicity assay based on Hoechst 33,342 staining of target cells. ( d ) Quantification of cytotoxicity of FuNV CAR -generated αCD19 CAR-T cells against CD19+ B cells (n = 5 individual replicates). ( e ) Cytotoxicity of FuNV CAR -generated αCD19 CAR-T cells against CD19− control cell lines (NIH 3T3, C2C12, B16-F10 and CT26) (n = 5 individual replicates). ( f ) Representative flow cytometry plots and quantitative analysis of Annexin V/PI staining demonstrating apoptosis of CD19⁺ B cells after co-culture with FuNV CAR -generated αCD19 CAR-T cells at different doses. Data are shown as the means ± SD. ****P < 0.0001, ***P < 0.001, *P < 0.05, and ns indicates P > 0.05
