摘　　要：阵发性睡眠性血红蛋白尿症(PNH)是一种良性克隆性疾病,该病以1个或多个葡萄糖磷脂酰肌醇(glycosyl phosphatidyl inositol,GPI)锚定蛋白(GPI-APs)缺失或减少的造血细胞克隆的扩增为特征,临床主要表现为血管内溶血、骨髓衰竭和血栓形成。GPI-锚定蛋白的缺失是PNH发病机制中重要一环。文章将从PNH的认识历程、锚蛋白的生物合成、功能及其与PNH发病机制的关系做一综述。Paroxymal noctural hemoglobinuria(PNH)is a kind of A benign clonal disease,characterized by expansion of hematopoietic cell clones with loss or decrease of glucosyphosphatidylinositol(GPI)anchor proteins(GPI-APs).The main clinical manifestations were intravascular hemolysis,bone marrow failure and thrombosis.Abnormal of GPI-APs played an important role in the pathogenesis of PNH.Therefore,this review will focus on the understanding history,biosynthesis and function of some GPI-APs and its relationship with nosogenesis of PNH.
