ABSTRACT
<p><b>OBJECTIVE</b>To investigate the anti-tumor immunity of the non-replicating recombinant vaccinia virus expressing HPV16 E6 and E7 proteins.</p><p><b>METHODS</b>C57BL/6 mice were immunized by non-replicating recombinant vaccinia virus (NTVJmE6E7), and then specific CTLs were determined. Immune protection effects were evaluated by challenges of different doses of TC-1 tumor cells. Immunotherapeutic effects in form of recurrence were evaluated on the tumor-removed mice.</p><p><b>RESULTS</b>Mice immunized by NTVJmE6E7 could generate TC-1 cell specific cytotoxic T lymphocyte (CTL). Mice boosted with NTVJmE6E7 could tolerate the challenge of 1 x 10(4) TC-1 cells. NTVJmE6E7 could effectively prevent the tumor recurrence in the tumor-removed mice.</p><p><b>CONCLUSION</b>NTVJmE6E7 can be taken as a candidate of therapeutic vaccine for HPV-associated tumors and their precursor lesions.</p>
