| Outline of Final Research Achievements |
We have prepared chimeric simian virus 40 (SV40) VP1 protein harboring a foreign epitope to induce aimed cytotoxic T lymphocyte (CTL). Immunization of the protein successfully induced CTL against the inserted foreign epitope, in which the level of CTL induction was over 50 times higher than that induced by classical immunization method using incomplete freund’s adjuvant. During examining the CTL induction property of SV40 VP1, we found that SV40 VP1 significantly induced immune responses against specific immune cells through a specific receptor expressed on the immune cells. We also found that the level of specific chemotactic cytokine secretions induced by SV40 VP1 was higher than that induced by LPS. In addition, as an application of the property of SV40 VP1 that induces strong immune responses against aimed CTL epitope within the SV40 VP1, we have constructed a vaccine against a refractory virus infection using SV40 VP1.
