摘要:

膜性肾性(MN)表现为器官特异性的自身免疫性疾病。1型血小板反应蛋白7A域(THSD7A)是继磷脂酶A2受体(PLA2R)之后发现的导致MN的又一个足细胞抗原。THSD7A及其抗体的发现使人们对MN有了新的认识。血清THSD7A抗体可与足细胞THSD7A抗原结合形成原位免疫复合物,导致足细胞损伤和蛋白尿的发生。初步研究结果显示,与PLA2R抗体类似,THSD7A抗体可用于指导MN的诊断、预后判断和病情监测。与PLA2R不同的是,THSD7A在人类和啮齿类动物的肾小球足细胞均高度表达,故可利用小鼠模型研究THSD7A相关性MN的发病机制。本文就THSD7A在MN中的研究进展作一综述。

Abstract:

Membranous nephropathy (MN) is an organspecific autoimmune disease.Thrombospondin type 1 domaincontaining 7A (THSD7A) is a new firmly recognized target antigen of MN.THSD7A antibody can induce podocyte injury and proteinuria by binding to THSD7A antigen on the surface of  podocyte.Though the discovery of THSD7A was more recent,limited data has addressed the role of THSD7A antibody in diagnosis,prognosis and monitor  of MN.In addition,we can use the mice model to study the pathogenesis of THSD7Aassociated MN because of the high expression of THSD7A on both human and murine podocyte.This review focused on the main discoveries and current knowledge of THSD7A and MN.
