What the trial is, and whether it could suit you
The etiologic mechanisms involved in multiple sclerosis (MS) are not yet fully understood. Indeed MS is a multifactorial disease involving genetic and environmental factors and Epstein-Barr-Virus (EBV) could be one of these factors. However the link between EBV infection and the immunological mechanisms underlying MS is not clear. Robust sero-epidemiological evidences support an association between EBV infection and MS, and immunological data suggest an altered/deficient immune response against this virus. In healthy individuals EBV produces a persistent infection that is tightly controlled by the immune system. In patients with MS, cellular and humoral immune studies demonstrate an altered response against the virus with a T-cell abnormal reactivity against the EBV-infected autologous B-cells, elevated humoral immune response to Epstein Barr Nuclear Antigen-1, and in the case of childre
