CD274 and neoplasm: Blocking B7-H1 offers a promising strategy for anticancer therapy.Although we showed the anti-tumor activity of B7-H1 blocking antibody, we noticed thatthe tumor growth was not completely stopped, but only modestly inhibited by targetingB7-H1, suggesting that B7-H1 is not the only molecule that mediates immune inhibition.Therefore, it should be combined with other anticancer approaches to achieve a morerobust effect.
