调节类风湿关节炎滑膜细胞基质金属蛋白酶表达的信号转导和相应的药物作用靶点

影响类风湿关节炎 (rheumatoidarthritis,RA)滑膜细胞基质金属蛋白酶表达的胞外信号包括T淋巴细胞、细胞因子、生长因子、干扰素和神经肽等,它们引起的信号在胞内主要依赖G蛋白偶联跨膜受体介导的途径和丝裂原激活的蛋白激酶途径转导。作用于这些信号或其转导过程的药物正成为治疗RA、预防RA关节破坏的新策略之一。

Signal transduction and drug targets for regulating matrix metalloproteinases expression in synoviocytes of rheumatoid arthritis

Extra-cellular signals, including T lymphoc ytes, cytokines,growth factors,interferons and neuropeptides, which could modulate matrix metalloproteinases expression in synoviocytes of rheumatoid arthritis(RA), are often mediated by G-protein-coupled Receptors (GPCR)-initiated signaling and mitogen-activated protein kinase (MAPK) cascades. Drug targets which aim at the extra-cellular signals or intra-cellular cascades is required for ameliorating inflammatory reaction and preventing joint destruction in RA.
