Effects of peptide L2 of human papillomavirus type 16 on the cytokine profile of dendritic cells in vitro

Abstract

BACKGROUND: The human papillomavirus is an etiological factor and a biological carcinogen in tumor lesions and cancer. Currently, there are several known possible mechanisms of immune evasion of human papillomavirus. Therefore, early methods for diagnosing papillomavirus infection and effective treatments. AIM: To analyze the cytokine profile should be established of dendritic cells in response should be determined to stimulation by peptide L2 of human papillomavirus type 16 in vitro. METHODS: Dendritic cell cultures were obtained from the blood of donors without signs of the human papillomavirus infection in history. A culture without stimulation was used as a control. As experimental groups, cultures synthesized peptide with L2 of the human papillomavirus type 16 were used. Enzyme-linked immunosorbent assay was used to determine the levels of pro- and anti-inflammatory cytokines. RESULTS: In comparison with spontaneous response in the control group after inoculation with peptide L2 of human papillomavirus type 16, increased IL-10, MCP-1, VEGF, IL-6, and IFN-γ concentrations and significant changes in IL-1β, IL-4, IL-8, IFN-α, and TNF-α concentrations were not detected. CONCLUSIONS: The results confirm the ability of the human papillomavirus to evade the antiviral immune response by affecting the synthesis of several cytokines.
