- Abstract: An important goal of immunotherapy against human papillomavirus (HPV) infection and cervical cancer is control of tumor growth. Here, we constructed bivalent DNA vaccines based on genetic fusion of HPV-16 E6 and E7 oncoproteins and glycoprotein D of HSV-1 (gD). Plasmids pRE4E7 and pRE4E6E7, encoding E7/gD and E6/E7/gD, respectively, were able to promote in vitro transcription of specific mRNAs and express the hybrid proteins. The DNA vaccines induced specific IFN-g CD8-dependent T cell responses in vaccinated female C57/Bl6 mice. Animals immunized with four doses of either pRE4E7 or pRE4E6E7 were complete protected to challenges with malignant TC-1 cells in a murine HPV-16-induced cancer model. We additionally evaluated levels of immunotherapeutic effect the bivalent DNA vaccines as determined in mice vaccinated on the same day or 5 days following the implantation of the malignant TC1 cells. The results indicated that both vaccine formulations were able to eradicate tumors from 40% the immunized animals. In conclusion, we showed that bivalent DNA vaccines expressing HPV-16 oncoproteins are promising candidates for therapeutic and prophylactic interventions of tumors induced by HPV-16
