ABSTRACT
In multiple sclerosis, an inflammatory attack results in myelin loss, which can be partially reversed by remyelination. Recent studies suggest that mature oligodendrocytes could contribute to remyelination by generating new myelin. Here, we show that in a mouse model of cortical multiple sclerosis pathology, surviving oligodendrocytes can indeed extend new proximal processes but rarely generate new myelin internodes. Furthermore, drugs that boost myelin recovery by targeting oligodendrocyte precursor cells did not enhance this alternate mode of myelin regeneration. These data indicate that the contribution of surviving oligodendrocytes to myelin recovery in the inflamed mammalian CNS is minor and inhibited by distinct remyelination brakes.
