The co-cultured PBMCs and Raji cells were separated by CD20 expressing. The CD20 antigens on surface of Raji cells were analyzed by flow cytometry. A life gate was set around CD20 positive cells; only those cells expressing this membrane protein were included, and 20,000 events were analyzed. A: The expression of Fas in Raji cells co-cultured with anti-CD20scFvFc/CD28/CD3ζ, anti-CD20scFvFc transduced T cells or untransduced T cells were analyzed by flow cytometry. B: The expression of Bcl-2 in Raji cells co-cultured with anti-CD20scFvFc/CD28/CD3ζ, anti-CD20scFvFc transduced T cells or untransduced T cells were analyzed by flow cytometry. C: The expression of Caspase-3 in Raji cells co-cultured with anti-CD20scFvFc/CD28/CD3ζ, anti-CD20scFvFc transduced T cells or untransduced T cells were analyzed by flow cytometry. (In experimental group, *represents p < 0.05 compared to control group at the same time point).
