项目摘要
Idiopathic nephrotic syndrome is one of the commonest kidney diseases in children. However, its etiology is not elucidated yet. We have evaluated the expression of co-stimulatory molecules on T and B lymphocytes (CD26, CD28、CD80/CD86、CTLA-4、CD69、CD26)by flow cytometry in 11 children with idiopathic nephrotic syndrome. In the result, CD40 ligand expressed on CD4 positive T lymphocyte and CD40 molecule expressed on CD19 positive B lymphocyte are significantly increased at primary onset comparing to at remission and in control children. In addition, western blot analysis revealed that phosphorylated-junk (p-junk), which is in downstream of CD40 signal, is only expressed in patients in active nephorotic phase. These findings suggest that T and B lymphocytes through CD40 and CD40 ligand could play some important role in pathogenesis of nephrotic syndrome. In addition, serum level of soluble CD30 is also significantly increased at primary onset comparing to at remission and in control children. CD30 is also expressed on activated T lymphocyte. Although further investigation is necessary, this finding also suggests mutual activation between T and B lymphocytes. CD40, CD40 ligand and soluble CD30 may be a good candidate of biomarker of nephritic syndrome.
特发性肾病综合征是儿童最常见的肾脏疾病之一,但其病因尚未阐明。我们评估了 T 和 B 淋巴细胞上的共刺激分子(CD26、CD28、CD80/CD86、CTLA-4、 11例特发性肾病综合征患儿流式细胞术检测CD69、CD26结果,CD4阳性T细胞上有CD40配体表达。与缓解期和对照儿童相比,初次发病时 CD19 阳性 B 淋巴细胞上表达的淋巴细胞和 CD40 分子显着增加。此外,蛋白质印迹分析显示,位于 CD40 信号下游的磷酸化垃圾 (p-junk),仅在肾病活动期患者中表达。这些研究结果表明,T 和 B 淋巴细胞通过 CD40 和 CD40 配体在肾病综合征的发病机制中发挥着重要作用。与缓解时相比,可溶性 CD30 在初次发病时也显着增加,并且在活化的 T 淋巴细胞上也表达 CD30,但这一发现也表明 CD40、CD40 配体之间的相互激活。可溶性CD30可能是肾病综合征生物标志物的一个很好的候选者。
