IFNG and melanoma: Flow cytometry analysis also showed IFN‐γ‐induced PD‐L1 membrane level decreased in a dose‐dependent manner after the exposure of melanoma cells (in A375 from 99.7% to 10.1% and SK‐MEL‐28 from 99.1% to 2.37%; Figure 3D,E) or A549 cells (from 87.4% to 16.5%; Figure S3A,B, Supporting Information) to Sunitinib.
