Abstract

Ovarian cancer is the sixth most common cancer in women worldwide and remains the leading cause of death due to gynecologic tumors. Bad prognosis is caused by advanced-stage high-grade disease. To reduce mortality and improve outcomes in this type of cancer, researchers attempt to introduce new therapies based on genetic engineering or immunotherapy. Th17 lymphocytes belong to the helper T cell population. These cells arise from immature CD4 + lymphocytes in the presence of IL-6 and TGF-β. Produce IL-17A, IL-17F, IL-21, IL-22, IL-26, IL-6, TNF-α. Interleukin-17 and Th17 cells play an active role in inflammation and autoimmune diseases. The existence of these cells was confirmed in different types of cancer. However, the exact role of IL-17 in tumor immunopathogenesis remains undefined. It has been reported that expression of interleukin-17 in tumor cells suppresses tumor progression through enhanced antitumor immunity or promotes tumor progression through an increase in inflammatory angiogenesis.
