Cervical cancer is one of the most common cancers in women worldwide. Persistent infection with human papillomavirus (HPV) is considered to be the etiological factor for cervical cancer. Therefore, an effective vaccine against HPV infections may lead to the control of cervical cancer. An ideal HPV vaccine should aim to generate both humoral immune response to prevent new infections as well as cell-mediated immunity to eliminate established infection or HPV-related disease. In the current study, we have generated a potential preventive and therapeutic HPV DNA vaccine using human calreticulin (CRT) linked to HPV16 early proteins, E6 and E7 and the late protein L2 (hCRTE6E7L2). We found that vaccination with hCRTE6E7L2 DNA vaccine induced a potent E6/E7-specific CD8+ T cell immune response, resulting in a significant therapeutic effect against E6/E7 expressing tumor cells. In addition, vaccination with hCRTE6E7L2 DNA generated significant L2-specific neutralizing antibody responses, protecting against pseudovirion infection. Thus, the hCRTE6E7L2 DNA vaccines are capable of generating potent preventive and therapeutic effects in vaccinated mice. Our data has significant clinical implications.
