Implication

Case-control study reveals elevated viral loads and expanded EBV-specific CD8+ T cells in rheumatoid arthritis, suggesting perturbed viral regulation drives heightened immune responses.

Key Points

Investigate EBV-specific T-cell and B-cell immune responses alongside viral load to determine whether defective immune control or elevated viral replication characterizes rheumatoid arthritis.
Quantified cell-associated EBV DNA copy numbers in circulating blood cells from patients with rheumatoid arthritis and demographically matched healthy virus carriers.
Profiled EBV-specific IgG antibody responses against lytic and latent antigens, as well as CD4+ and CD8+ T-cell responses against EBV and human cytomegalovirus antigens.
Patients with rheumatoid arthritis exhibited a 7-fold higher EBV DNA copy number in circulating blood cells and broader, elevated IgG responses against latent and lytic viral antigens compared to controls.
EBV-specific CD8+ T-cell populations expanded substantially and correlated directly with cellular EBV viral load, whereas EBV-specific CD4+ T-cell and cytomegalovirus-specific T-cell responses remained unchanged.
