Role of retinoid X receptors in oligodendrocyte development and function in health and disease.

IGBMC, Department of development and stem cells, Strasbourg (CU), France

Retinoid x receptor gamma (RXRg) acts as a ligand regulated transcription factor and is recognized as the key positive regulator of remyelination in multiple sclerosis (MS), but the mechanism(s) of such activity is not known. Our published and new functional, and genomic data indicate that RXRg plays also an important role as a positive regulator of oligodendrocyte differentiation during development, the process which may involve some known but also new, previously unexpected pathways. The project will focus first on the validation of selected pathways / targets for their importance in oligodendrocyte differentiation and myelination process using siRNA, viral tools associated with transcriptomic analyses in vitro. In the second phase, in vivo validation will be carried out in dedicated existing and new genetic mouse models. The implications of such findings for understanding of MS pathophysiology and future treatments will be inferred from in vitro screens and the analysis of the mouse model of MS.
