Role of Nuclear Receptors on the Progression of Multiple Sclerosis: A Review.

Multiple sclerosis (MS) is the consequence of early-onset inflammatory demyelination and progressive neurodegenerative lesions in the central nervous system (CNS). Despite the unclear pathogenesis of MS, two main processes occur, oligodendrocyte repair and lipid metabolism. Nuclear receptors have been observed to have a role as ligand sensors, regulators of transcriptional factors, and modulators of gene expression. One member of this family, the retinoid X receptor (RXR), which forms a heterodimeric complex with liver X receptor (LXR), have been implicated in the pathophysiology of MS. Moreover, it has been expressed that LXR receptors play pivotal role in the regulation of inflammation, oxidative stress responses, and cholesterol metabolism in phagocytes in active MS lesions. This review aimed to study role of RXR and LXR in MS pathogenesis.
