Glycopeptide and uses thereof
A glycolipopeptide comprising a carbohydrate component, a peptide component and a lipid component, for use as a therapeutic or prophylactic vaccine. Also provided are monoclonal and polyclonal antibodies that recognize the glycolipopeptide of the invention, as well as uses thereof.
1. A glycolipopeptide comprising:
at least one carbohydrate component comprising a MUC-1 glycopeptide comprising at least one B-epitope;
at least one peptide component comprising a microbial peptide comprising at least one T-epitope; and
at least one lipid component comprising Pam 3 CysSK n , wherein n=0, 1, 2, 3, 4, or 5.
2. The glycolipopeptide of claim 1 wherein the T-epitope comprises a helper T epitope.
3. The glycolipopeptide of claim 1 wherein the T-epitope comprises amino acid sequence KLFAVWKITYKDT (SEQ ID NO:3).
4. The glycolipopeptide of claim 1 wherein the glycopeptide comprises at least one O-GalNAc moiety.
5. The glycolipopeptide of claim 1 wherein the MUC-1 glycopeptide comprises the amino acid sequence TSAPDT(α-D-GalNAc)RPAP.
6. The glycolipopeptide of claim 1 wherein the lipid component comprises Pam 3 CysSK 4 .
7. A pharmaceutical composition comprising:
the glycolipopeptide of claim 1 and
a pharmaceutically acceptable carrier.
8. The pharmaceutical composition of claim 7 comprising a liposome comprising the glycolipopeptide.
9. The glycolipopeptide of claim 1 , wherein the glycolipopeptide comprises an N-terminus comprising the lipid component.
10. The glycolipopeptide of claim 1 , wherein the lipid component comprises Pam 3 CysSK 4 , the peptide component comprises KLFAVWKITYKDT (SEQ ID NO:3), and the carbohydrate component comprises TSAPDT-(αGalNAc)-RPAP.
