IL-8 is a chemotactic cytokine with proinflammatory and growth-promoting activities. The release of IL-8 was measured in supernatants of cultured peripheral blood monocytes (PBM) that were obtained from patients with glomerulonephritis (GN) and healthy controls. Spontaneous and lipopolysaccharide (LPS)-induced IL-8 release was significantly higher in PBM isolated from patients with IgA nephropathy (IgAN) and membranous nephropathy (MN) compared with normal controls. These results raise the question of whether IL-8 contributes to the ongoing pathogenesis of GN. We cannot relate IL-8 release to clinical and laboratory parameters in IgAN and MN patients. Thus, disease progression in vivo may not be accompanied by increased or sustained IL-8 release.
白细胞介素-8(IL-8)是一种具有促炎和促生长活性的趋化细胞因子。从肾小球肾炎(GN)患者和健康对照者获取的培养外周血单核细胞(PBM)上清液中检测IL-8的释放情况。与正常对照相比,从IgA肾病(IgAN)和膜性肾病(MN)患者分离出的PBM中,自发和脂多糖(LPS)诱导的IL-8释放显著更高。这些结果提出了一个问题,即IL-8是否参与了GN的持续发病机制。我们无法将IgAN和MN患者的IL-8释放与临床和实验室参数联系起来。因此,体内疾病进展可能不会伴随IL-8释放增加或持续。
