白细胞介素-17 (IL-17)被认为是一种由CD4+ CD45RO+记忆T细胞产生的促炎细胞因子。与骨关节炎患者相比,类风湿关节炎(RA)患者滑膜中IL-17的过量产生被检测到。本研究检测了IL-17刺激RA患者成纤维细胞样滑膜细胞后的差异表达基因。在这些基因中,我们确定了以下基因:肿瘤坏死因子刺激基因6 (TSG-6)、IL-6、IL-8、GRO-β和骨形态发生蛋白6,其表达量是未刺激对照的3.6 - 10.6倍。IL-17增强了TSG-6(一种透明质酸结合蛋白)的表达,并呈时间和剂量依赖性。IL-17与IL-1β、肿瘤坏死因子-α对TSG-6、IL-6、IL-8的表达有叠加作用。有丝分裂原激活的蛋白激酶p38似乎是IL-17调控TSG-6表达所必需的,SB203580的抑制作用表明。我们的研究结果支持了IL-17在RA发病机制中很重要的假设,它有助于细胞因子的不平衡产生,并参与结缔组织重塑。
Interleukin-17 (IL-17) has been characterized as a proinflammatory cytokine produced by CD4+ CD45RO+ memory T cells. Overproduction of IL-17 was detected in the synovium of patients with rheumatoid arthritis (RA) compared with patients with osteoarthritis. This study examines differentially expressed genes after the stimulation of fibroblast-like synoviocytes of RA patients by IL-17. Among these genes we identified the following: tumor necrosis factor-stimulated gene-6 (TSG-6), IL-6, IL-8, GRO-β, and bone morphogenetic protein-6 with an expression 3.6–10.6-fold that in the unstimulated control. IL-17 augmented the expression of TSG-6, a hyaluronan-binding protein, in a time- and dose-dependent manner. IL-17 showed additive effects with IL-1β and tumour necrosis factor-α on the expression of TSG-6, IL-6 and IL-8. The mitogen-activated protein kinase p38 seems to be necessary for the regulation of TSG-6 expression by IL-17, as shown by inhibition with SB203580. Our results support the hypothesis that IL-17 is important in the pathogenesis of RA, contributing to an unbalanced production of cytokines as well as participating in connective tissue remodeling.
