Intrathecal antibodies cross-react with EBV BRRF2 and human antigens in multiple sclerosis
This study identifies a specific intrathecal antibody signature in a subset of multiple sclerosis patients that targets an Epstein-Barr virus BRRF2 motif and cross-reacts with human CNS antigens, suggesting a molecular link between EBV infection and MS pathogenesis while offering a potential biomarker for disease stratification.
