Abstract
The present invention provides a nucleic acid sequence encoding a melanoma antigen recognized by T lymphocytes, designated MART-1. This invention further relates to bioassays using the nucleic acid sequence, protein or antibodies of this invention to diagnose, assess or prognoses a mammal afflicted with melanoma or metastata melanoma. This invention also provides immunogenic peptides derived from the MART-1 melanoma antigen and a second melanoma antigen designated gp100. This invention further provides immunogenic peptides derived from the MART-1 melanoma antigen or gp100 antigen which have been modified to enhance their immunogenicity. The proteins and peptides provided can serve as an immunogen or vaccine to prevent or treat melanoma.
Claims3
A pharmaceutical composition comprising gp100 (SEQ ID NO:
- 27) or an immunogenic peptide consisting of 5-20 contiguous amino acids within the gp100 sequence and a pharmacologically acceptable excipient, diluent or carrier.
A method of treating melanoma in a mammal comprising administering a pharmaceutical composition comprising gp100 (SEQ ID NO:
- 27) or an immunogenic peptide consisting of 5-20 contiguous amino acids within the gp100 sequence to said mammal in an effective amount to stimulate the production of immune cells.
An immunogenic composition for immunizing a mammal comprising an immunogenically-effective amount of gp100 (SEQ ID NO:27) or an immunogenic peptide consisting of 5-20 contiguous amino acids within the gp100 sequence in a pharmacologically acceptable carrier.
