Figure 2

Flow cytometry analysis of the expression of 78-kDa glucose-regulated protein (GRP78) in plasma cells of synovial fluid. The representative expressions of GRP78 in CD138+ plasma cells of synovial fluid of follicular synovitis, diffuse synovitis, and osteoarthritis (OA) are shown in (a-c), respectively. The significantly increased mean fluorescent intensity of GRP78 in CD138+ plasma cells of rheumatoid arthritis (RA) relative to OA (P = 0.001) and the upregulated mean fluorescent intensity of GRP78 in CD138+ plasma cells of follicular synovitis relative to that of diffuse synovitis (P = 0.002) are shown in (d) and (e), respectively. DS, diffuse synovitis; FITC, fluorescein isothiocyanate; FS, follicular synovitis; MFI, mean fluorescent intensity; PE, phycoerythrin.
