It has been reported that Th17 cells shows antitumor effect by recruiting and activating effector immune cells.57 The population of Th17 cells which differentiates in the presence of IL‐6, IL‐1β, and IL‐23, expresses high levels of IL‐2, IL‐33, and IL‐18r1, coexpression of RORC (RAR‐related orphan receptor C) and T‐bet, and significantly enhanced the ability to produce IFN‐γ.58 Synergistic role of IL‐17 produced by these cells along with IFN‐γ stimulates recruitment of tumor‐infiltrating effector T cells. This evidence concerns the gene IL6 and neoplasm.
