Abstract :

Multiple sclerosis (MS) is a chronic infl ammatory disease of the central nervous system, believed to be caused by the autoimmune destruction of myelin sheath surrounding the nerve fi bres of the brain and spinal cord, leading to demyelination and scarring. Th e disease is amongst the leading causes of neurological disability. However, little is known regarding its etiology or the mechanisms that drive the chronic infl ammation which leads to the autoimmune destruction of the myelin sheath. Both genetic and environmental factors have been implicated. Of the environmental factors, Epstein-Barr virus (EBV) has received considerable attention in recent years. A number of studies have shown elevated levels of EBV-specifi c immune responses in patients MS, both pre- and post onset of the disease. More recently, EBV-infected cells were reported to be present in white matter lesions in MS tissues, however other studies could not confi rm this fi nding. Our recent work has shown the presence of EBV-infected cells in preselected active MS lesions. Interestingly, the distribution of EBV-infected cells correlated with the distribution of IFNα-expressing cells. We further showed that this proinfl ammatory cytokine was expressed in macrophages and microglia in MS lesions and that EBV can trigger IFNα expression in an in vitro model. However, what role EBV plays in the disease process is not clear. Here, we discuss some potential roles this virus could play in the pathogenesis of MS.
