MSI cancer
Microsatellite Instability (MSI) is one of the major phenotypes of genomic instability in human cancers. MSI is characterized by the accumulation of insertion/deletion mutations, which develop as a consequence of MMR deficiency. MSI cancers have a significantly elevated mutational load. Indels at defined coding microsatellites lead to the generation of frameshift peptide neoantigens. These neoantigens can be recognized by the host’s immune system and elicit a strong anti-tumor immune response.
Our group has pioneered research on the immune biology of MSI cancers and prepared the first-in-human vaccine against these cancers. This is particularly important, as it opens the possibility of tumor-preventive vaccines for Lynch syndrome patients who have an inherited predisposition to develop MSI cancer (for more information on MSI cancer pathogenesis click here).

We are dedicated to connecting basic research and clinic. Therefore we are highly interested in unraveling biological mechanisms that may be used for development of therapeutic and preventive approaches. Our research on development of the first vaccine for MSI cancers was awarded with Felix Burda Award 2015 in the category “Medicine and Science”.
