A disease-specific convergence of host and Epstein-Barr virus genetics in multiple sclerosis.

ABSTRACT: Recent sero-epidemiological studies have strengthened the hypothesis that Epstein-Barr virus (EBV) may be a causal factor in multiple sclerosis (MS). Given the complexity of the EBV-host interaction, various mechanisms may be responsible for the disease pathogenesis. Furthermore, it remains unclear whether this is a disease-specific process. Here, we showed that genes encoding EBV interactors are enriched in loci associated with MS but not with other diseases and in prioritized therapeutic targets. Analyses of MS blood and brain transcriptomes confirmed a dysregulation of MS-associated EBV interactors affecting the CD40 pathway. Such interactors were strongly enriched in binding sites for the EBV nuclear antigen 2 (EBNA2) viral transcriptional regulator, often in colocalization with CCCTC
