As we observed a higher expression of antigen presentation molecules and PD-L1 especially in response to inflammatory signal, IFNγ, in lung cancer cell lines sensitive to EGFR inhibitors, we assessed the baseline expression of various immune-related genes in lung cancer cell lines from Cancer Cell Line Encyclopedia (http://www.broadinstitute.org/ccle) in relation to the PD-L1 expression. Here, CD274 is linked to lung carcinoma.
