For years researchers have believed a link exists between the Epstein-Barr virus (EBV) and multiple sclerosis. But scientists have had a hard time finding a precise association.
Now, the National Institutes of Health (NIH) are reporting another possible connection. Researchers at the Center for Autoimmune Genomics and Etiology at Cincinnati Children’s Hospital Medical Center have found a viral protein in EBV-infected cells. They think that the protein may turn on a “switch” that activates genes that are associated with an increased risk of autoimmune diseases. MS, of course, is an autoimmune disease.
Scientists know that the EBV infection can produce a protein called EBNA2. In this new research, they found that EBNA2 activates some of the human genes associated with the risk of lupus and several other autoimmune diseases, including multiple sclerosis. Simply put, it flips that autoimmune disease “switch.” To continue to read more click the link: Epstein-Barr Virus Link to MS
