摘要:游离HA被肝脏摄取,在那里被降解和再循环。许多慢性肝病,包括感染(乙型或丙型肝炎)、毒性(酒精和药物)、遗传(血色病)、自身免疫和恶性肿瘤,会导致肝炎,进而可能发展为肝纤维化和肝硬化;导致肝功能受损,从而引起循环中HA水平的急剧上升。
透明质酸(HA)是一种高分子量的阴离子多糖(1,000-10,000 kD),由重复的二糖单元组成。它是连接组织细胞外基质中多种糖胺聚糖成分之一。
游离HA被肝脏摄取,在那里被降解和再循环。许多慢性肝病,包括感染(乙型或丙型肝炎)、毒性(酒精和药物)、遗传(血色病)、自身免疫和恶性肿瘤,会导致肝炎,进而可能发展为肝纤维化和肝硬化;导致肝功能受损,从而引起循环中HA水平的急剧上升。
数据显示HA水平与局部炎症和疾病严重程度之间存在相关性。最近的研究表明,尿液中的HA水平是膀胱癌的指标,HA水平与肝病相关,且慢性阻塞性肺病患者肺部的HA分解情况也与之有关。此外,还发现类风湿关节炎患者的血清中HA水平升高。
透明质酸酶联免疫吸附测定(HA ELISA)是一种竞争性96孔板检测方法,提供了一种简单、有效的方法,用于测定人和动物生物样本或细胞上清液中的透明质酸(HA)水平。
