γ/δ T cells maintain their intrinsic cytolytic activity against Daudi cells after receptor transfection. ZA-activated γ/δ T cells (a + b; closed symbols), OKT3-stimulated MACS-isolated γ/δ T cells (a + b; open symbols), OKT3-activated PBMC (c + d; closed symbols), and OKT3-stimulated MACS-isolated CD8+ T cells (c + d; open symbols) were expanded and electroporated as described above (Figs. 1 and 2). Mock-electroporated T cells (dotted lines; mock) served as controls. After over-night culture, the cytolytic capacity of TCR- (a + c) and CAR- (b + d) transfected T cells towards Daudi cells was examined at indicated effector to target ratios in a standard 4–6 h chromium release assay. The percentage of lysed cells was calculated. Data are presented as means ± SEM derived from 3 to 5 independent experiments, each performed in technical triplicate. P-values calculated by unpaired Student’s t-test are presented in Additional file 1: Table S7
