Figure 6. Constitutive or inducible expression of PD-Ls, HLA-II and HLA-I in EA cell line.
The EA cell line untreated (CTR), treated with IFN-γ, TNF-α or culture supernatants from NK cells unstimulated (none) or stimulated with the indicated cytokines, was analyzed by flow cytometry for the expression of PD-Ls, HLA-II and HLA-I. Panel A and B show two independent experiments performed using NK cells purified from two unrelated healthy donors. White profiles refer to cells incubated with isotype-matched mAbs. Values inside each histogram indicate the MFI.
