IL24 and neoplasm: Our group previously found that delivery of IL‐24 via a CRAd (ZD55‐IL‐24), in combination withdacarbazine, has a greater antitumor effect in melanoma cells than either of these agents when used alone.30 ZD55‐IL‐24 attaches to tumor cells using CAR; however, the expression of CAR in most types of cancer cells is low or absent.20 Therefore, IL‐24 expression levels following ZD55‐IL‐24 infection of cancer tumor cells are still insufficient.
