ARF1 and neoplasm: Our above‐given data have shown that the Arf1‐ablation‐stimulated DCs produced a great amount of IL‐1β and type I IFNs, both of which have critical roles in mediating anticancer immune responses.[43, 44] We supposed that the IL‐1β and type I IFNs cytokines might be responsible for anti‐tumor immunity induced by the Arf1‐ablated tumor cells.
