Mechanisms underlying remyelination with special focus on demyelination models of multiple sclerosis / 浙江大学学报·医学版

ABSTRACT

Failure to remyelinate and rewrap the demyelinated axons has been revealed as the major hurdle for treatment of multiple sclerosis (MS), and the bottleneck is the inability of oligodendrocyte progenitor cell (OPC) to differentiate into mature oligodendrocyte. Remyelination is a spontaneous regenerative process, which includes activation, migration and differentiation of OPC, and is believed to protect the axon and further halt neurodegeneration. In recent years, studies have identified many potential drug targets for efficiently promoting OPC differentiation in demyelination models, such as metformin, clemostine, and drug targets as myelin transcription factor 1-like protein (Myt1L), N-methyl-D-aspartic acid (NMDA) receptor, connexin 43 (Cx43), G protein coupled receptor 17 (GPR17), κ opioid receptor (KOR), sterol 14α-demethylase (CYP51), Δ14-sterol reductase (TM7SF2), emopamil-binding protein (EBP). This review summarizes the recent progress on the mechanisms underlying the activation, migration and differentiation of OPC in remyelination with special focus on studies using demyelination models of MS, which may provide insights of further exploring new therapeutic strategies for MS.
