Enhanced TLR2 responses in multiple sclerosis.

ABSTRACT: The roles of the microbiome and innate immunity in the pathogenesis of multiple sclerosis (MS) remain unclear. We have previously documented abnormally low levels of a microbiome-derived Toll-like receptor (TLR)2-stimulating bacterial lipid in the blood of MS patients and postulated that this is indicative of a deficiency in the innate immune regulating function of the microbiome in MS. We postulated further that the resulting enhanced TLR2 responsiveness plays a critical role in the pathogenesis of MS. As proof-of-concept, we reported that decreasing systemic TLR2 responsiveness by administering very low-dose TLR2 ligands attenuated significantly the mouse model of MS, experimental autoimmune encephalomyelitis. Studies of Toll-like receptor responses in patients with MS have been conflict
