These results have important implications for a possible viral trigger in MS as they indicate that chronic demyelination in TMEV-infected mice is initiated in the absence of demonstrable neuroantigen-specific autoimmune responses and are consistent with a model wherein early myelin damage is mediated via primarily by mononuclear phagocytes recruited to the CNS and activated by pro-inflammatory cytokines produced by TMEV-specific Thl cells.	./cache/cord-023143-fcno330z.txt	./txt/cord-023143-fcno330z.txt
