Dr. Beatrice Wasser awarded DGfI Herbert Fischer Prize for Neuroimmunology
Each year, the German Society for Immunology (DGfI) recognizes young scientists who have made an outstanding contribution in the field of immunology. This year, Dr. Beatrice Wasser, a Postdoc in the group of Prof. Frauke Zipp and Prof. Stefan Bittner in the Department of Neurology, was award the Herbert Fischer Prize for Neuroimmunology for her […]...more

Study with identical twins shows that the early form of multiple sclerosis has a specific pattern
The tremendous heterogeneity of the human population presents a major obstacle in understanding how autoimmune diseases like multiple sclerosis (MS) contribute to variations in human peripheral immune signatures. To minimize heterogeneity, SFB researchers from Munich and Muenster made use of a unique cohort of 43 monozygotic twin pairs clinically discordant for MS and searched for […]...more

Breakthrough: SFB scientsists explain pathomechanism of Susac Syndrome
Münster. Neuroinflammation is often associated with blood-brain-barrier dysfunction, which contributes to neurological tissue damage. In a paper published in the renowned journal Nature Communications SFB 128 scientists from Mueenster reveal the pathophysiology of Susac syndrome (SuS), an enigmatic neuroinflammatory disease with central nervous system (CNS) endotheliopathy.

Münster. Neuroinflammation is often associated with blood-brain-barrier dysfunction, which contributes to neurological tissue damage. In a paper published in the renowned journal Nature Communications SFB 128 scientists from Mueenster reveal the pathophysiology of Susac syndrome (SuS), an enigmatic neuroinflammatory disease with central nervous system (CNS) endotheliopathy. By investigating immune cells from the blood, cerebrospinal fluid, and CNS of SuS patients, Dr. Catharina Gross and her team demonstrate oligoclonal expansion of terminally differentiated activated cytotoxic CD8+ T cells (CTLs). Neuropathological data derived from both SuS patients and a newly-developed transgenic mouse model recapitulating the disease indicate that CTLs adhere to CNS microvessels in distinct areas and polarize granzyme B, which most likely results in the observed endothelial cell injury and microhemorrhages. The autors show that blocking T-cell adhesion by anti-α4 integrin-intervention ameliorates the disease in the preclinical model. Similarly, disease severity decreases in four SuS patients treated with natalizumab along with other therapy. Their study identifies CD8+ T-cell-mediated endotheliopathy as a key disease mechanism in SuS and highlights therapeutic opportunities.
