Research interests

Despite the fact that the central nervous system (CNS) is considered an immune privileged organ and central tolerance is supposed to eliminate self-reactive T cell clones, myelin-reactive T cell responses drive CNS autoimmunity in multiple sclerosis (MS). We are interested in cellular and molecular mechanisms that regulate disease initiation and progression. Tryptophan metabolism is a key process that shapes immunosuppressive T cell responses and we have shown that downstream signaling indeed limits autoimmune neuroinflammation. In addition, we are currently investigating the impact of the gut microbiome composition on encephalitogenic  T cell responses. Delineating the complex interplay between the microbiome, antigen presentation and T cell activation will eventually help us to develop novel strategies for MS therapy.
