Intradermal vaccination via gene gun efficiently delivers DNA vaccines into dendritic cells (DCs) of the skin, resulting in the activation and priming of antigen-specific T cells in vivo. We have previously demonstrated that intradermal delivery of DNA vaccines encoding single-chain trimer (SCT) composed of the most immunogenic epitope of human papillomavirus type 16 (HPV-16) E6 protein (aa49-57), beta2-microglobulin, and MHC class I heavy chain (SCT-E6) can bypass antigen processing and lead to stable cell-surface presentation of E6 peptides. We also showed that co-administration of DNA vaccines with DNA encoding anti-apoptotic proteins can prolong the survival of DNA-transduced DCs, resulting in significant enhancement of antigen-specific CD8(+) T cell immune responses. In the current study, we hypothesized that combining the SCT strategy and antiapoptotic strategy may further enhance DNA vaccine potency by augmenting antigen-specific CD8(+) T cell immune responses and antitumor effects in vaccinated mice. Here, we show that C57BL/6 mice vaccinated with SCT-E6 DNA combined with antiapoptotic protein Bcl-xL DNA generated enhanced E6-specific CD8(+) T cell immune responses compared to mice vaccinated with SCT-E6 DNA and a non-functional mutant Bcl-xL (mtBcl-xL) DNA. Furthermore, we show that mice treated with SCT-E6 and Bcl-xL DNA generated enhanced anti-tumor effects against E6-expressing tumor cells (TC-1/Luciferase) compared to mice treated with SCT-E6 and mtBcl-xL DNA.
