Significance of NF-?B in immunopathogenesis of Graves disease / 中国病理生理杂志

ABSTRACT

AIM:To investigate the activity of NF-?B in peripheral blood mononuclear cells (PBMCs) from patients with Graves disease (GD) and the significance in immunopathogenesis of GD.METHODS:Peripheral blood was collected from 22 untreated GD,20 treated GD with tapazole more than 1 year,and 25 healthy volunteers. PBMCs were isolated from the blood by histopaque-1077 density-gradient centrifugation. The activity of NF-?B in PBMCs was analyzed using gel electrophoretic mobility shift assay (EMSA). The contents of IL-1?,IL-6 and TNF-? were tested by radioimmunoassay.RESULTS:The activity of NF-?B in PBMCs of untreated GD group was increased remarkably,compared with that in the treated group and control (P
