Deskripsi

The immune mechanisms underlying synovitis and joint tissue destruction in rheumatoid arthritis (RA) remain incompletely defined. Here, the authors demonstrate that ACPA+ RA patients have activated clonally expanded cytotoxic GZMB+ CD8+ T cells in blood and synovium that target and are activated by citrullinated antigens to mediate cell killing.
