The WT-5-stimulated T cell line was then examined for their reactivity against NSCLC cell lines, including NCI-H1975 (HLA-A2− T790M+), NCI-H1975-A2 (HLA-A2+ T790M+), HCC827 (HLA-A2− T790M−), PC9 (HLA-A2+ T790M−), PC9/ZD (HLA-A2+ T790M+), 11–18 (HLA-A2+ T790M−), and YM-21 (HLA-A2+ T790M−), by IFN-γ ELISPOT assay. The gene discussed is IFNG; the disease is non-small cell lung carcinoma.
