Peripheral peptidolgycan (PGN) is present within antigen-presenting cells in the central nervous system (CNS) of multiple sclerosis (MS) patients, possibly playing a role in neuroinflammation. Accordingly, PGN is linked with disease progression in the animal model of MS, experimental autoimmune encephalomyelitis (EAE), but the role of specific PGN-sensing proteins is unknown. Here we report that the progression of EAE was dependent on the intracellular PGN sensors NOD1 and NOD2 and their common downstream adaptor molecule, receptor interacting protein 2 (RIP2; also known as Ripk2 and RICK). We found that RIP2, but not toll-like receptor 2 (TLR2), played a critical role in the activation of CNS-infiltrating dendritic cells. Our results suggest that PGN in the CNS is involved in the pathogenesis of EAE through the activation of infiltrating dendritic cells via NOD1-, NOD2- and RIP2-mediated pathways.
