Abstract
Objective: The production of class-switched high-affinity autoantibodies derived from organized germinal centers (GCs) is a hallmark of many autoimmune inflammatory diseases, including rheumatoid arthritis (RA). TANK-binding kinase 1 (TBK-1) is a serine/threonine kinase involved in the maturation of GC follicular helper T (Tfh) cells downstream of inducible costimulator signaling. We undertook this study to assess the therapeutic potential of TBK-1 inhibition using the small-molecule inhibitor WEHI-112 in antibody-dependent models of inflammatory arthritis. Methods: Using the models of collagen-induced arthritis (CIA), antigen-induced arthritis (AIA), and K/BxN serum-transfer–induced arthrit..
