Field of Research

Multiple sclerosis is a disease which affects mostly young adults, resulting in increasing neurological constraints. During the course of the disease, mature oligodendrocytes are lost leaving demyelinated axons at a high risk to degenerate. Remyelination prevents axons from degeneration. Oligodendrocyte precursor cells are able to generate new myelin sheaths, a process which is possible but does not always occur in patients with multiple sclerosis especially at the later stages of the disease. The reasons for these differences and decreasing repair capacities remain unclear, mainly because the interactions between axons and oligodendroglial cells that promote remyelination are largely unknown. My current research focuses on investigating changes in the interactions that occur between demyelinated axons and oligodendroglial cells during the process of remyelination. Understanding these processes is crucial in order to develop new therapies that aim at enhancing remyelination.

This project is funded by the German Research Council (Deutsche Forschungsgemeinschaft, DFG).


Demyelination in the corpus callosum is induced by using Cuprizone and Lysolecithin models. The distribution of sodium channals isoforms and other proteins of interest during remyelination is studied by fluorescence techniques and confocal microscopy. The activity of nerve fibers is assessed through measuring compound action potentials. In addition, the ultrastructure is investigated by electron microscopy in cooperation with the electron microscopy department at the Institute of Pathology in Tübingen.
