The overarching goal of our research consists in elucidating the mechanisms underlying central nervous system (CNS) autoimmunity, with an emphasis on disease progression and neurodegenerative phenotypes. For this purpose, the lab routinely employs in vivo model of neuroinflammation in combination with cutting-edge “omics” technologies (Next-Generation sequencing, mass-spectrometry proteomics) and the latest approaches for genetic manipulation in mice. A consistent part of the lab research efforts is focused on multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE). In fact, MS is perhaps the most paradigmatic autoimmune disease and provides an excellent framework to investigate the interactions between the immune and nervous systems in health and disease.
In parallel to our work on MS, the lab is also interested in elucidating the role played by the immune compartment in the etiopathogenesis of disorders there were once considered purely neurodegenerative such as Alzheimer’s disease and Parkinson’s disease. In particular, we are keen to characterize the contribution of inflammatory stress to protein misfolding in the brain. We also intend to explore the possible involvement of peripheral and CNS resident immune cells in modulating disease susceptibility and clinical manifestations.
