Some cytokines help the cellular immune response eliminate and control HPV infection, including interferon (IFN)-γ, which enhances the expression of the major histocompatibility complex (MHC) in tumor cells and inhibits angiogenesis [8] and tumor necrosis factor (TNF)-α, which exhibits antitumor properties and inhibits the growth of some cell lineages transformed by HPV [9]. The gene discussed is TNF; the disease is neoplasm.
