The Collaborative Research Center 128 “Multiple Sclerosis” is entering its third round. As the German Research Association announced, the major project with locations in Münster, Mainz and Munich will be supported for a further four years (until mid-2024). Speaker Prof. Heinz Wiendl, Co-Spokesperson Prof. Frauke Zipp (Mainz) and other scientists are researching multiple sclerosis – a chronic inflammatory and neurodegenerative disease of the central nervous system. Their focus is on the interaction between the immune and nervous systems on a molecular, cellular and systems biological level. The 35 principal investigators and their teams analyse the changes in the immune system underlying the disease, effects the attack of the immune system has on the central nervous system and how these consequences can be modulated with the latest therapies. The 22 individual projects are tackling a wide range of topics, including the role of the intestinal microbiome in inflammation and nerve destruction in MS, the patterns of nerve damage that MS patients e.g. in MRI images show and the effect of various MS drugs on the immune system. In the next four years, the focus of her work will be on coping with illnesses. This means both better control and monitoring of the now widespread drugs for treating MS and translation – i.e. the transfer of research results into patient care and – the other way around – the use of knowledge from clinical practice for work in the laboratory.
