New study sheds light on how Epstein-Barr virus may contribute to multiple sclerosis

medicalxpress - Multiple sclerosis (MS) is a chronic autoimmune disorder that attacks the central nervous system. For years, Epstein-Barr virus (EBV) has been strongly linked to MS, as nearly every person diagnosed with the condition shows evidence of past EBV infection.…

AI Summary: Researchers report that immune responses to Epstein‑Barr virus are implicated in multiple sclerosis, with EBV‑reactive CD4+ T cells enriched in people with MS. The work provides mechanistic evidence connecting prior infection to neuroinflammation and suggests antiviral or immune‑directed strategies might be viable prevention or treatment avenues — assuming we like attacking tiny viral culprits.
