Infections can trigger or exacerbate the course of Multiple Sclerosis, and both bacterial and viral agents have been implicated. These agents are recognized by host cells via pathogen-associated molecular patterns activating TLRs. We investigated the role that PAMPs play in the animal model Experimental Autoimmune Encephalomyelitis, and found various MyD88-dependent PAMPs can participate as the adjuvant to induce EAE. Studies with IRAK1-deficient mice suggest that signaling through TLRs is not required in the target organ to develop disease. This suggests that PAMPs play an important role in priming of autoreactive T cells in EAE and potentially MS.
