N2 - Paralleling our previous mechanistic studies of glatiramer acetate (GA; Copaxone) activity, we show that GA curbs the expression of Toll-like receptor (TLR) 9 and the universal adapter protein Myd88 in mice with EAE, the animal model for multiple sclerosis. Concurrent with enhanced dendritic cell (DC) production of IL-10, GA interferes with OPN, IL-17, and ROR gamma expression in DCs of mice with EAE, and suppresses brain expression of the EAE-induced chemokines, MIP1α and β, IP-10 and RANTES. Thus GA not only biases dendritic cells towards an anti-inflammatory phenotype, but also suppresses the expression of factors that affect the blood–brain barrier penetration during neuroinflammation.
