The present study investigates the expression of immune biomarkers, PD-L1 and HLA-1 on novel lung cancer cell lines (H838, H838-EGFR, A549, A549-ALK, HCC 827, NCI 1650, TWIT, Jacket). PD-L1 and HLA-1 characterisation were initially performed and analysed via flow cytometry. These results showed that the expression of PD-L1 and HLA-1 varies across the cell lines from high percent to low. The effect of IFNy on biomarkers expression was also investigated following a 48 hour incubation period. of the cell lines analysed the expression of PD-L1 increases with IFNy stimulation whilst HLA-1 remains relatively unchanged. Trypan blue assays for cell viability were performed, showing that when stimulated, cells were 100% viable whereas viability decreases upon IFNy exposure.
