N2 - B cells of people with multiple sclerosis (MS) are more responsive to IFN-γ, corresponding to their brain-homing potential. We studied how a coding single nucleotide polymorphism (SNP) in IFNGR2 (rs9808753) co-operates with Epstein-Barr virus (EBV) infection as MS risk factors to affect the IFN-γ signaling pathway in human B cells. In both cell lines and primary cells, EBV infection positively associated with IFN-γ receptor expression and STAT1 phosphorylation. The IFNGR2 risk SNP selectively promoted downstream signaling via STAT1, particularly in transitional B cells. Altogether, EBV and the IFNGR2 risk SNP independently amplify IFN-γ signaling, potentially driving B cells to enter the MS brain.
