In my lab at the University of Mainz we are working to understand the complex interactions between the immune and nervous systems in neuroinflammatory diseases, such as Multiple Sclerosis (MS). Until very recently, scientists assumed that any activity of the immune system within or around the central nervous system (CNS) was a hallmark of pathology. However, multiple new lines of evidence support the notion that immune support is required for optimal neuronal survival following CNS injury and for the higher brain function. This immune activity, however, needs to be under a tight control and when the control mechanisms fail, autoimmune attack on the brain takes place. Our recently discovery of meningeal lymphatic system that drains CNS (Louveau et al., Nature 2015), may provide an additional insight into the mechanism that regulates CNS autoimmunity.

Our goal is to elucidate the cellular and molecular mechanisms underlying the autoimmune attack on the CNS. We are using cutting edge technologies in neuroscience and immunology to address these challenging yet extremely interesting questions.
