Webb1 apr. 2003 · Fig. 1 Demyelination in multiple sclerosis occurs by two major mechanisms: (A) primary injury to the myelin sheath with relative preservation of oligodendrocytes, or (B) direct injury to oligodendrocytes (oligodendrogliopathy).Following demyelination of the axon there is either (i) remyelination with axonal preservation, or (ii) axonal death. WebbA prominent feature of demyelinating diseases such as multiple sclerosis (MS) is the degeneration and loss of previously established functional myelin sheaths, which results in impaired signal propagation and axonal damage.
