Identification of Immunogenic MHC Class II Tyrosinase-Derived Peptides Using HLA-DR1 and HLA-DR4 Transgenic Mice

The immunogenicity of “novel” MART-1 and Tyrosinase class-II peptides was assessed in transgenic mice. Tyrosinase141-161 peptide was found to be immunogenic and endogenously processed in the HLA-DRβ1*0101 and HLADR β1*0401 transgenic mice with peptide specific production of IFNγ or IL-5 respectively. The MART-129-43 peptide was only found immunogenic in HLA-DRβ1*0101 mice.
