Increased PD-L1 expression on DCs loaded with the lysate of tumor cells infected with NDV. (A) A representative flow cytometry plot exhibiting PD-L1 expression on the three types of DCs. (B) Graph demonstrating the MFI of PD-L1 on the three types of DCs induced from 12 patients with lung cancer. (C) Graph illustrating the percentage of PD-L1 expression on the three types of DCs induced from peripheral blood monocytes of 12 patients with lung cancer. *P<0.05. n.s., not significant; NDV-TCL-DCs, Newcastle Disease Virus-tumor cell lysate-dendritic cells; PD-L1, programmed death ligand 1; MFI, mean fluorescence intensity.
