Global gene expression analysis using cDNA microarrays has proven to be a sensitive method to gain insight into molecular pathways mediating multiple sclerosis (MS) activity and to develop and refine the molecular taxonomy of the disease. This method was applied as a tool to investigate molecular heterogeneity of MS related gene transcripts in the aim of distinguishing between transcripts that trigger disease activity and account for direct genotype-phenotype correlation, and those whose expression is altered as a downstream effect of other genes. This review summarizes the current state of gene expression microarray applications for the study of MS, and specifically emphasizes the results of gene expression studies using peripheral blood mononuclear cells (PBMC) that were shown to be useful for better understanding of disease related pathways, monitoring of therapeutic responses to various drugs and prediction of clinical outcome. In the long run it is expected that the information provided by cDNA microarrays experiments will allow the determination of key molecular players involved in MS pathogenesis, and lead to better management of the disease using targeted treatments that will prevent its progression.
