MHC CLASS I PEPTIDE EPITOPES FROM THE HUMAN 5T4 TUMOR-ASSOCIATED ANTIGEN

摘要

There is provided an MHC class I peptide epitope from 5T4 antigen. In particular, there is provided a peptide epitope of 5T4 which comprises one of the following: (i) the amino acid sequence shown as SEQ ID No.2; (ii) the minimal epitope from the amino acid sequence shown as SEQ ID No.3; (iii) the minimal epitope from the amino acid sequence shown as SEQ ID No.4. (iv) the minimal epitope from the amino acid sequence shown as SEQ ID No. 5. (v) the minimal epitope from the amino acid sequence shown as SEQ ID No.6. (vi) the minimal epitope from the amino acid sequence shown as SEQ ID No.7. There is also provided a vaccine comprising such a peptide (or precursor thereof) and its use to treat and/or prevent a disease, in particular a cancerous disease.
