嗜酸粒细胞阳离子蛋白(eosinophil cationic protein,ECP)是嗜酸粒细胞(eosinophil,EOS)分泌的4种强碱性蛋白中的一种,其他还有碱性蛋白(major basic protein,MBP)、嗜酸粒细胞衍生神经毒素/嗜酸粒细胞蛋白X(eosinophil derived neurotoxin/eosinophil protein X)、嗜酸粒细胞过氧化物酶等。大量研究资料表明,ECP来源于EOS,并且是EOS活化和转归的生物标志~(〔1〕)。ECP蛋白具
Eosinophil cationic protein (ECP) is one of the four strong basic proteins secreted by eosinophils (EOS), and other major basic proteins (MBP) Eosinophil derived neurotoxin / eosinophil protein X, eosinophil peroxidase and the like. A large number of research data show that ECP is derived from EOS and is a biomarker of activation and prognosis of EOS (1). ECP protein with
