In multiple sclerosis (MS), axons of the central nervous system lose their myelin sheaths, and there is also death of oligodendrocytes. Although some demyelinated axons rebuild their membranes so that they can conduct action potentials in the absence of myelin insulation, others do not; and loss of the myelin thus impairs impulse conduction either temporarily or permanently. Mounting evidence also suggests that loss of central myelin may have the secondary consequence of making axons more sensitive to damage or may, in itself, produce changes that impair axonal integrity, thereby leading to cumulative loss of axons that culminates in irreversible neurological deficits (Waxman, 2006
). While a number of treatments such as the beta interferons (IFN-ß) and glatirimer acetate (GA) are now available for the treatment of MS, and clinical studies using autologous haematopoietic stem cell transplantation (HSCT) and monoclonal antibody interventions in MS patients have shown profound suppression of inflammatory
