Abstract |
One of the characteristic features of the pathogenesis of rheumatoid arthritis is synovial hyperplasia. We have reported previously that metastatic lymph node 51 (MLN51) and granulocyte-macrophage colony-stimulating factor (GM-CSF) are involved in the proliferation of fibroblast-like synoviocytes in the pathogenesis of rheumatoid arthritis. In this study, we have found that: (1) GM-CSF-mediated MLN51 upregulation is attributable to both transcriptional and post-translational control in rheumatoid arthritis fibroblast-like synoviocytes; (2) p38 mitogen-activated protein kinase plays a key role in the upregulation of MLN51; and (3) FLICE-inhibitory protein is upregulated downstream of MLN51 in response to GM-CSF, resulting in the proliferation of fibroblast-like synoviocytes. These results imply that GM-CSF signaling activates mitogen-activated protein kinase, followed by the upregulation of MLN51 and FLICE-inhibitory protein, resulting in fibroblast-like synoviocyte hyperplasia in rheumatoid arthritis.
