Multiple Sclerosis (MS) characterized by demyelination and axonal degeneration is a chronic inflammatory disease of the central nervous system (CNS). Recent studies have shown that dysregulated miRNAs alter immune responses, so they may have roles basis on various genetic diseases such as MS and may be potential targets for biomarkers and new therapeutic approaches. In this study, we evaluated the dysregulation of miRNA expression levels at MS and MS stages. We also discussed the potential of these miRNAs to be biomarkers and/or therapeutic targets in MS.
