TNFR2 signaling in oligodendrocyte precursor cells suppresses their immune-inflammatory function and detrimental microglia activation in CNS demyelinating disease.

Multiple Sclerosis (MS) is a chronic degenerative disease of the central nervous system (CNS) characterized by inflammation, demyelination, and progressive neurodegeneration. These processes, combined with the failure of reparative remyelination initiated by oligodendrocyte precursor cells (OPCs), lead to irreversible neurological impairment. The cytokine tumor necrosis factor (TNF) has been implicated in CNS repair via activation of its cognate receptor TNFR2 in glia.
