Further Information

Our laboratory is very translational: In the morning, the physicians from the group see patients with immunodeficiencies, take blood from them, and bring it to the Center for Translational Cell Research (ZTZ), in which our working group is housed. Here, we extract the genomic DNA and search for the mutations that could explain the immunodeficiency. For this we use next generation sequencing which enables us to read all human genes in one experiment. However, each person carries about 250 new mutations that are not present in their parents. How do you find out the disease-causing mutations among all these hundreds of variants?

For this purpose, we developed a database that identifies the genetic variants that may be causing the disease, similar to the search for a specific fingerprint in the database of the Federal Criminal Police Office. However, we often encounter mutations that have not yet been described or investigated. Therefore, in a next step, we have to confirm these genetic results through functional studies.

Moreover, we are interested in the role of the microbiome for the immune system. During the last decade it became clear that the microbiome plays a prominent role in shaping the immune system. Here we try to answer the question how the microbiome can affect the everyday disease course of our patients.

Finally, we started to research the impact of epigenetic changes to the immune system: We follow the hypothesis that an aberrant methylation of genes leads to immune deficiency or immune dysregulation. Epigenetics goes beyond genetics. Every cell has the same genetic information – its DNA. But what determines that the cells in the eye can see, and the cells in the nose can smell? It is the epigenetic regulation of genes which determines these differences, for instance by the process of DNA methylation. We are using cutting edge multi-omics profiling and integrative bioinformatic analysis to unravel the pathway underlying immune-mediated diseases. By combining genomic, epigenomic, transcriptomic, and proteomic analysis, we will exploit defined pathways to improve the diagnosis and the mechanistic understanding of the pathophysiology of our patients.
