Complex interactions between the immune system and the central nervous system (CNS) in health and disease

The goal is to elucidate the cellular and molecular mechanisms underlying these interactions in neurodegenerative, neurodevelopmental, and mental disorders as well as in physiology (including healthy aging). We showed that the brain function is dependent, in part, on the function and integrity of the immune system and that immune molecules (cytokines) can play neuromodulatory roles. The fascination with immunity and its role in neurophysiology is what brought the team to a breakthrough discovery of meningeal lymphatic vessels that drain the CNS into the peripheral lymph nodes and thus serve as a physical connection between the brain and the immune system. This finding challenged the prevailing dogma of CNS being an “immune privileged organ” and opened new avenues to mechanistically study the nature of neuroimmune interactions under physiological and pathological conditions. The implications of this work are broad and range from Autism to Alzheimer’s disease through neuroinflammatory conditions, such as Multiple Sclerosis.
