Fig. 2. The expression of NKG2DLs in pancreatic carcinoma cell lines and cytotoxic activity of NKG2D-CAR T cells.
a Flow cytometry histograms showed the expression of NKG2DLs on SW1990, CAPAN2, and PANC28. b Line plots displayed the cytotoxicity of Mock T, NKG2D-CAR T, NC-NKG2D-CAR T, and KD2-NKG2D-CAR T against the indicated cell lines at a different effector to target (E:T) ratios for 16 h. The expression of CD69 (c), IFN-γ (d) and Gzm B (e) as well as the expression of CD107a (f) were measured by flow cytometry after co-incubating with PANC28 at a 9:1 ratio for 16 h (left). MFI and percentage were statistically analyzed and shown in column chart (middle and right) (n = 3). Data were representative of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, NS not significant.
