Working Group Odermatt
With studies on zebrafish, Prof. Dr. Benjamin Odermatt is treading an innovative path in establishing molecular biological, physiological and genetic foundations for the search for effective MS (multiple sclerosis) drugs.
The almost transparent larvae of the zebrafish serve researchers worldwide as a model organism. This is because many processes in the larvae's body can be easily observed under the microscope.
Together with AG Odermatt, the fish larvae at the University of Bonn, for example, were partially »humanised« by replacing one of their genes, which was described for MS, with the corresponding human gene. Professor Odermatt and his team are investigating how the zebrafish larvae form nerve tissue with the human gene.
Specific active substances that stimulate the formation of nerve tissue in »humanised« fish have an increased probability of also being effective in humans. And this is precisely where a great opportunity lies.
In cooperation with other research groups – also from outside Bonn – the Odermatt group is also dedicated to researching other diseases: These include congenital human embryonic malformations such as cleft palate, bladder and kidney disorders and infant tumours. The AG uses the transparent fish larvae to develop a better understanding of these diseases.
For this purpose, it has been possible for all scientific working groups to have fish larvae generated via core-facility zebrafish for several years.
Mr. Odermatt set up this Core Facility (CF) of the Bonn Medical Faculty and has been the scientific director of this CF since then.

Exploring myelination in vivo
Disorders of white matter »myelin« are the cause of many common neurological diseases. Despite the major involvement of oligodendrocytes in CNS myelination in health and disease, there are still many uncertainties when it comes to questions about the various factors that cause oligodendrocytes to provide proper initial myelination, remyelination, or even fine-tuning of myelination that enables CNS plasticity for learning and memory.
To better understand the influence of the different activities of glial cells and neurons on the myelination process, we aim to simultaneously observe this cell activity and myelination in zebrafish in vivo. Zebrafish are commonly used as a vertebrate model organism for neural development and myelination. In addition, the zebrafish has proven to be a powerful system for studying other cellular activities in vivo using fluorescent reporter proteins.
Understanding what protects our nerves
There are mainly two types of cells in our brain and nervous system. Nerve cells, also called neurons, are responsible for transmitting and processing electrical signals ...
