Figure 4From: Enhanced interaction between natural killer cells and lung cancer cells: involvement in gefitinib-mediated immunoregulationGefitinib up-regulates NKG2Dligands on tumor cells. (A-B), ULBP1, ULBP2 and MICA expression was evaluated on A549 (A) and H1975 (B) tumor cells after co-culture with NK cells in the presence or absence of gefitinib. Two independent experiments were performed.Back to article page
