Fig. 1: The expression of PD-L1 in NSCLC cell lines and cells with acquired resistance to various anticancer drugs.
From: Exosomal PD-L1 promotes tumor growth through immune escape in non-small cell lung cancer

a The basal expression of PD-L1 in NSCLC cells was determined by western blot analysis. b, c PD-L1 expression in parental and resistant cells was determined by western blot analysis and flow cytometry. MFI, median fluorescence intensity; CR-1, cisplatin resistance; GR, gefitinib resistance; ER, erlotinib resistance; WR, WZ4002 resistance; CLR, CL-387785 resistance; CR, crizotinib resistance
