Data from a previous study suggested that peripheral blood monocytes in patients with rheumatoid arthritis (RA) may be activated. Therefore, in this study we sought further evidence of 'presynovial' activation of monocytes. Our results show that phenotypic changes are demonstrable in peripheral blood monocytes in patients with RA, including increased expression of CR3 (CD11b/CD18) and FcRI (CD64). However, changes are most extensive in synovial monocytes/macrophages and especially for HLA-DR and intercellular adhesion molecule-1 (ICAM-1) (CD54). We conclude that monocyte/macrophage activation is most evident within the joint, and that 'presynovial' changes occur but are of limited extent.
先前一项研究的数据表明,类风湿关节炎(RA)患者的外周血单核细胞可能被激活。因此,在本研究中,我们寻求单核细胞“滑膜前”激活的进一步证据。我们的结果显示,RA患者外周血单核细胞存在可证实的表型变化,包括CR3(CD11b/CD18)和FcRI(CD64)表达增加。然而,滑膜单核细胞/巨噬细胞中的变化最为广泛,尤其是HLA-DR和细胞间黏附分子-1(ICAM-1)(CD54)。我们得出结论,单核细胞/巨噬细胞激活在关节内最为明显,“滑膜前”变化确实存在,但程度有限。
