More Evidence for Epstein-Barr Virus' Role in MS
-
Epstein-Barr Virus (EBV) is a suspect in the development of multiple sclerosis (MS), and recent research developments have strengthened that connection. In 2022, two studies received quite a bit of attention. One showed that EBV seroconversion occurs in the years prior to MS diagnosis in virtually every patient, and that serum levels of the neuronal damage biomarker neurofilament light (NfL) rose following EBV infection. Another paper showed anti-EBNA (Epstein-Barr nuclear antigen) antibodies in the cerebrospinal fluid cross-react with the central nervous system antigen GlialCAM in some MS patients

@putin The new research takes the work a step further by revealing a population of T cells in MS patients that appear to be responding directly to EBV during active viral disease. That could be telling because most people who experience an EBV infection and experience mononucleosis recover, and some never even realize they have been infected. As a herpes virus, EBV remains in a latent state in B cells and other immune cells
