EBV as the ‘gluten of MS’ hypothesis: Bypassing autoimmunity


      The EBV as the ‘gluten of MS’ hypothesis discussed by Drosu et al. in a recent Editorial envisages the existence of similar mechanisms leading to celiac disease and multiple sclerosis, such as induction of immunity against an ubiquitous exogenous antigen - gluten and EBV, respectively - and subsequent development of autoimmunity that is maintained by persistence of the initial trigger. While this hypothesis provides the rationale for treating MS with antivirals to lower EBV load, it can be misleading when trying to translate concepts of T cell-B cell interaction and autoimmunity development in celiac disease to multiple sclerosis. Here, we propose that EBV might act as the driver of multiple sclerosis without involving autoimmunity.
