Vaccine comprising epitope of heat shock protein, and use thereof
A vaccine containing an epitope of a heat shock protein 90 and uses thereof are disclosed. The epitope(s) of heat shock protein 90 has the amino acid sequence of SEQ ID NO: 1 and/or 2. A multi-epitope vaccine containing the epitope(s) and a method for treating or preventing cancer using the same are disclosed.
1. A multi-epitope vaccine comprising an adjuvant and a mixture of two different MHC class II-specific epitopes from a heat shock protein 90 (HSP90), wherein said two MHC class II-specific epitopes consisting of the amino acid sequence of SEQ ID NO: 1 and the amino acid sequence of SEQ ID NO: 2.
2. The multi-epitope vaccine according to claim 1 , which induces production of an antibody and/or activation of immune cells that recognizes heat shock protein 90 as an antigen.
3. A multi-epitope vaccine comprising an adjuvant and nucleic acid molecules encoding the two MHC class II-specific epitopes, as described in claim 1 .
4. A vaccine composition comprising the vaccine of claim 1 .
5. The composition according to claim 4 , further comprising STING (Stimulator of Interferon gene) agonist.
6. The composition according to claim 5 , further comprising an immune checkpoint inhibitor against any one selected from the group consisting of CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), PD-1 (Programmed cell death protein 1), LAG-3 (Lymphocyte Activation Gene-3), TIM-3 (T-cell Immunoglobulin and Mucin-domain containing-3), TIGIT (T-cell Immunoreceptor with IG and ITIM domain), and VISTA (V-domain Ig Suppressor of T cell Activation).
7. A method of administering the vaccine of claim 1 comprising administering an effective amount of the vaccine to produce an antibody binding a heat shock protein 90.
8. A composition comprising an adjuvant and an isolated heat shock protein 90 (HSP90)-specific MHC class II epitope, wherein the epitope consists of a peptide selected from a group consisting of SEQ ID NOs: 1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.
9. A method for manufacturing the multi-epitope vaccine of claim 1 , comprising the step of synthesizing SEQ ID NO: 1 and SEQ ID NO: 2 that induces production of antibodies.
10. A method for manufacturing the composition of claim 8 , comprising the step of synthesizing a peptide selected from SEQ ID NOs: 1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.
11. A vaccine composition comprising the vaccine of claim 3 .
12. A method of administering the vaccine of claim 3 comprising administering an effective amount of the vaccine to produce an antibody binding a heat shock protein 90.
13. A composition comprising an adjuvant and a nucleic acid molecule encoding an epitope consisting of a peptide selected from a group consisting of SEQ ID NOs: 1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.
