T 淋巴细胞导致类风湿性关节炎滑膜炎症的机制尚不清楚。在这里,我们回顾了表明滑膜 T 细胞、相邻巨噬细胞和成纤维样滑膜细胞 (FLS) 之间细胞接触的重要作用的数据。因此,由细胞因子、内皮迁移、细胞外基质或自身抗原激活的T细胞可以通过至少通过β-整联蛋白和膜细胞因子介导的细胞膜相互作用促进细胞因子,特别是TNFα、巨噬细胞和FLS产生金属蛋白酶。由于由此诱导的可溶性因子可能反过来直接促进 T 细胞激活,因此可能会产生正反馈循环。这些新途径代表了令人兴奋的潜在治疗靶点。
Mechanisms whereby T lymphocytes contribute to synovial inflammation in rheumatoid arthritis are poorly understood. Here we review data that indicate an important role for cell contact between synovial T cells, adjacent macrophages and fibroblast-like synoviocytes (FLS). Thus, T cells activated by cytokines, endothelial transmigration, extracellular matrix or by auto-antigens can promote cytokine, particularly TNFα, metalloproteinase production by macrophages and FLS through cell-membrane interactions, mediated at least through β-integrins and membrane cytokines. Since soluble factors thus induced may in turn contribute directly to T cell activation, positive feedback loops are likely to be created. These novel pathways represent exciting potential therapeutic targets.
