Pool sequencing and HPLC-MS allowed for the first time the discovery of sequence motifs of naturally processed peptides, which have been isolated from MHC class I and II molecules. The experimental results have been achieved in cooperation with immunobiologists, in particular with H.G. Rammensee’s group.
The allele-specific sequence motifs are of fundamental importance for the understanding of the cellular immune response. This knowledge allows the construction of patient-specific novel vaccines such as lipopeptide vaccines and mRNA vaccines with CTL and T-helper responses against tumors, viruses and bacteria. The molecular origin of autoimmune diseases is a further research topic in the context of patient-specific peptide motifs.
