The present disclosure relates to an immunologically active peptide-biliverdin conjugate (I), a preparation method therefor and an application thereof in cancer diagnosis, and/or tumor immunotherapy, and/or tumor “photothermal immunotherapy” (tumor photothermal therapy combined with immunotherapy). The conjugate to which the present disclosure relates not only may stimulate an organism to generate a tumor-immune effect, but also may relieve and/or eliminate tumor inflammation, remodel a tumor inflammatory microenvironment and achieve photothermal cancer immunodiagnosis and immunotherapy. The conjugate to which the present disclosure relates has high biocompatibility, good stability and an extended half-life. The conjugate is prepared from an immunologically active peptide and biliverdin by means of chemical synthesis. A peptide end of the conjugate exercises the function of immunoregulation, and a pigment end thereof exercises functions such as tumor imaging diagnosis, tumor photo-thermal ablation, immune inflammatory microenvironment regulation and the like. The conjugate may significantly enhance the antitumor effect and effectively inhibit tumor metastasis and recurrence.

The present invention provides a fusion protein comprising an HPV cancer-causing protein segment, a coding sequence thereof and an application thereof in preparing drugs for detecting or treating HPV-related diseases. The fusion protein can simultaneously induce the humoral immunity and the cellular immunity for a high-risk HPV cancer protein and has anti-cancer activity in vivo.

The invention relates to a truncated L1 protein of the Human Papillomavirus Type 6, a virus-like particle consisting of the truncated L1 protein, a vaccine comprising said virus-like particle, and the use of the vaccine in the prevention of condyloma acuminatum or HPV infections.
