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(More)
The mammalian immune system constitutively senses vast quantities of commensal bacteria and their products through pattern recognition receptors, yet excessive immune reactivity is prevented under homeostasis. The intestinal microbiome can influence host susceptibility to extra-intestinal autoimmune disorders. Here we report that polysaccharide A (PSA), a(More)
B cells are of increasing importance as a target for multiple sclerosis treatment. Here we show that GA treatment of mice with experimental autoimmune encephalomyelitis (EAE) biases cytokine production by B cells towards cytokines associated with regulation in MS including interleukin (IL)-4, -10 and -13 and reduces pro-inflammatory IL-6, IL-12, and TNF(More)
We recently showed that B cells reduce CNS inflammation in mice with experimental allergic encephalomyelitis (EAE). Here, we demonstrate that adoptively transferred CD5/CD19+ B cells protect against EAE severity. Furthermore, we show that glatiramer acetate (GA), a therapeutic for relapsing multiple sclerosis treatment, amplifies this effect. Transfer of(More)
