456-EBV Cross-Reactivity of Multiple Sclerosis
This research investigates the immunological connection between the Epstein-Barr virus (EBV) and the development of multiple sclerosis (MS) through a mechanism known as molecular mimicry. Scientists discovered that immune cells initially targeting the EBV protein EBNA1 can mistakenly attack the brain protein anoctamin-2 (ANO2) because they share similar structural features. By utilizing single-cell sequencing and T cell receptor analysis, the study demonstrates that these cross-reactive T cells are prevalent in patients and possess highly cytotoxic phenotypes. Experimental models further show…
