By Sally Robertson, BSc. The term demyelination refers to loss of the myelin sheath that surrounds and protects axons in the central nervous system. Demyelination occurs as the result of diseases that damage the myelin sheath or the cells that form it. Diseases that are characterized by this loss of myelin are referred to as demyelinating diseases. The myelin sheath covers and insulates axons, aiding the conduction of electrical signals between nerves.
Viral infections cause a variety of demyelinating diseases in animals and humans. Demyelinating diseases are defined as disorders of the central or peripheral nervous system with destruction of myelin and relative preservation of axons.he pathogenesis of the demyelination is different with different infections; these mechanisms range from direct infection and lysis of oligodendrocytes to immune destruction of myelin or supporting cells by cell-mediated immune responses, antibody, or cytokines (see Box 1-1).
