摘要
酸敏感离子通道(acid-sensing ion channels,ASICs)是一类胞外H+激活的阳离子通道,属于阿米洛利敏感的上皮钠通道/退变素(epithelial Na+channels/degenerin,ENa C/DEG)超家族中的一员,该通道广泛分布在周围和中枢神经系统中,并且具有重要的生物学功能。近来研究表明,ASICs在类风湿关节炎发病过程中发挥着重要作用。该文对ASICs的细胞生物学特点以及ASICs在类风湿关节炎中对炎症、疼痛和软骨损伤等方面的作用进行综述。
Acid-sensing ion channels ( ASICs) are cation chan-nels activated by extracellular H+, which belong to the amilo-ride-sensitive epithelial Na+ channels/degenerin ( ENaC/DEG ) superfamily. These channels are widely expressed in the central and peripheral nervous systems and have crucial biological func-tions. Recent studies have demonstrated that ASICs play an im-portant role in the pathogenesis of rheumatoid arthritis. This re- view concerns the cell biological characteristics of ASICs as well as its role in inflammation, pain, cartilage destruction and other aspects in rheumatoid arthritis.
