On the one hand, Tc17 has more survival advantages and superior direct cytotoxicity compared to Tc1 cells [9]; Type 17 T cells secrete IL-17, GM-CSF, and IFN-γ to recruit immune cells such as T cells, B cells, granulocytes, and macrophages to the tumor tissue [9–11]. The gene discussed is CSF2; the disease is neoplasm.
