Therefore, we investigated the levels of IFN-γ and IL-17A secreted by γδ T cells in PB and tissues, and found higher levels of IL-17Ain both PB and tissues of OC patients, but lower levels of IFN-γ secreted by γδ T cells, while IL-17A was inclined to infiltrate the tumor milieu of OC. Here, IFNG is linked to neoplasm.
