Immunotherapeutic effects of TCL-E5 and TCL-E5-pulsed DCs: two novel HPV therapeutic vaccine candidates.
Aim: This study investigated the potential of HPV16 E5 oncoprotein-modified tumor cell lysate (TCL-E5) and dendritic cells (DCs) pulsed with TCL-E5 (TCL-E5-pulsed DCs) to enhance antitumor immunity in a murine model.
Materials and methods: For generation of TCL-E5, TC1 tumor cells were transduced with lentiviral particles harboring E5 protein. Moreover, the cell supernatants were prepared from DCs pulsed with TCL-E5. Their immunological responses and antitumor effects were investigated in a mouse model.
Results: The TCL-E5-pulsed DCs regimen could direct immunity toward Th1 and CTL responses, leading to tumor volume reduction and high percentage of tumor-free mice.
Conclusion: The TCL-pulsed DCs regimen could not induce significant antitumor effects compared to TCL-E5-pulsed-DCs regimen indicating main role of E5 in vaccine development.
期刊介绍：
Many aspects of the immune system and mechanisms of immunomodulatory therapies remain to be elucidated in order to exploit fully the emerging opportunities. Those involved in the research and clinical applications of immunotherapy are challenged by the huge and intricate volumes of knowledge arising from this fast-evolving field.
