New insights into the pathogenesis of rheumatoid arthritis

Abstract excerpt

T lymphocytes play a critical role in the inflammatory process of rheumatoid arthritis (RA). Studies in a new animal model of RA, created by implanting human inflamed synovium into SCID mice, have confirmed that the production of matrix-degrading enzymes and pro-inflammatory cytokines is ultimately under T-cell control. T-cell dysfunction in RA patients also alters T-cell dynamics, resulting in profound...
