EBV is a candidate trigger of rheumatoid arthritis (RA). We determined both EBV-specific T cell and B cell responses and cell-associated EBV DNA copies in patients with RA and demographically matched healthy virus carriers. Patients with RA showed increased and broadened IgG responses to lytic and latent EBV-encoded Ags and 7-fold higher levels of EBV copy numbers in circulating blood cells. Additionally, patients with RA exhibited substantial expansions of CD8(+) T cells specific for pooled EBV Ags expressed during both B cell transformation and productive viral replication and the frequency of CD8(+) T cells specific for these Ags correlated with cellular EBV copy numbers. In contrast, CD4(+) T cell responses to EBV and T cell responses to human CMV Ags were unchanged, altogether arguing against a defective control of latent EBV infection in RA. Our data show that the regulation of EBV infection is perturbed in RA and suggest that increased EBV-specific effector T cell and Ab responses are driven by an elevated EBV load in RA.

Increased Frequency of EBV-Specific Effector Memory CD8+ T Cells Correlates with Higher Viral Load in Rheumatoid Arthritis
