Microarray analysis of multiple sclerosis (MS) lesions obtained at autopsy revealed increased
transcripts of genes encoding inflammatory cytokines, particularly interleukin-6 and -17, interferon- ? and associated downstream pathways. Comparison of two poles of MS pathology—
acute lesions with inflammation versus ‘silent’ lesions without inflammation—revealed differentially transcribed genes. Some products of these genes were chosen as targets for therapy of experimental autoimmune encephalomyelitis (EAE) in mice. Granulocyte colony-stimulating factor is upregulated in acute, but not in chronic, MS lesions, and the effect on ameliorating EAE is more pronounced in the acute phase, in contrast to knocking out the immunoglobulin Fc receptor common ? chain where the effect is greatest on chronic disease. These results in EAE corroborate the microarray studies on MS lesions. Large-scale analysis of transcripts in MS lesions elucidates new aspects of pathology and opens possibilities for therapy.
