Table 1b:
Anti-tumor roles of IL-17
Species | Cancer Type | Mechanism/s |
---|---|---|
Human | Cervical adenocarcinoma | Increased number of IL-17+ cells in patients were significantly correlated with the absence of vaso-invasion, less infiltration depths and smaller tumor growths. (117) |
Mouse | fibrosarcoma | IL-17-overexpresssion drives upregulation of MHC I and II, thereby making fibrosarcoma cells increasingly susceptible to anti-tumor T cells. (118) |
Human | Esophageal cancer | IL-17 drives chemokine production from the tumors, leading to the infiltration of cytotoxic neutrophils, CD8+CTLs and dendritic cells resulting in better tumor control and patient survival. (119, 120) |
Mouse | Lung Cancer | IL-17 controls tumor growth and metastasis by enhancing the cytotoxic potential of anti-tumor CD8+ T cells (121), and by increasing IFN-γ production from anti-tumor T cells and NK cells. (122) |
Mouse | Breast Cancer | IL-17 inhibits the accumulation of MDSCs in tumor microenvironment by suppressing their proliferation and triggering apoptosis. (123) |
Human | Colorectal cancer | Individuals with higher IL-17 expression exhibited better disease control and survival which is linked to increased infiltration of cytotoxic CD15+ neutrophils (124). |
