Abstract

Epstein-Barr virus and Mycobacterium avium subsp. paratuberculosis (MAP) have been associated to multiple sclerosis (MS). We searched for antibodies against the homologous peptides Epstein-Barr virus nuclear antigen 1 (EBNA1)400-413, MAP_0106c protein (MAP)121-132, and myelin basic protein (MBP)85-98 on a MS Sardinian cohort, showing that these antibodies are highly prevalent among MS patients compared to healthy controls. Competitive assay demonstrated that antibodies recognizing EBNA1400-413 and MAP121-132 cross-react with MBP85-98, possibly through a molecular mimicry mechanism. Indeed, the fact that peptides from different pathogens can be cross-recognized by antibodies targeting self-epitopes supports the hypothesis that EBV and MAP might trigger autoimmunity through a common target. © 2014.
