The synovial fluid is rich in the RA cell, which is a polymorphonuclear leukocyte that has encountered and engulfed immune complexes and complement.
While several RA cell types contribute to cartilage and bone destruction, including neutrophils (in the joint space itself) and chondrocytes (sequestered deep within the cartilage), the primary cells that propagate articular damage at the pannus's leading edge are osteoclasts and synovial fibroblasts (SF).
To explore expression differences between normal and RA cells, we first screened datasets that met the needs of our design by literature mining in the Gene Expression Omnibus (GEO) database.
Furthermore, they demonstrated that the oxidation of TrxR1 was irreversible by the addition of NADPH in RA cells incubated for long periods.
