The immunogenicity of "novel" MART-1 and Tyrosinase class-II peptides was assessed in transgenic mice. Tyrosinase(141-161) peptide was found to be immunogenic and endogenously processed in the HLA-DRbeta1*0101 and HLA-DRbeta1*0401 transgenic mice with peptide specific production of IFNgamma or IL-5 respectively. The MART-1(29-43) peptide was only found immunogenic in HLA-DRbeta1*0101 mice.
