摘要
目的探讨 CD40及其配体( CD40L)在系统性红斑狼疮( SLE)发病机制中的作用及临床意义。方法应用逆转录-聚合酶链反应( RT-PCR)检测 34例 SLE患者外周血单一核细胞( PBMC)中 CD40和 CD40配体 mRNA的表达水平。结果活动期 SLE患者 PBMC中 CD40配体的阳性表达率为 88.24%( 30/34),明显高于正常人对照组( 50.00%, 15/30),差异有非常显著性( P< 0.01);活动期 SLE患者 PBMC中 CD40配体 mRNA表达的平均水平( 0.6970± 0.1214)亦明显高于正常人对照组( 0.2684± 0.0795),差异有非常显著性 (P< 0.01)。活动期 SLE患者 PBMC中 CD40的阳性表达率和 CD40 mRNA的表达水平与对照组相比差异均无显著性( P >0.05)。结论 CD40配体的异常表达可能在 SLE疾病活动和发展过程中起重要作用,检测 SLE患者 PBMC中 CD40配体的表达水平可作为疾病的活动性指标之一。
Objective To investigate the role of CD40 and CD40 ligand (CD40L) in the pathogenesis of systemic lupus erythematosus (SLE) and its clinical significance. Methods Applying RT-PCR technique to semiquantitatively analyze CD40 and CD40L mRNA expression in PBMC from 34 SLE patients. Results Compared with normal controls, the positive CD40L expression accounted for 88.24% of active SLE patients(P< 0.001); the mean level of CD40L mRNA expression in active SLE group was markedly increased as well (P< 0.0001). However, there were no statistical differences in positive rate of CD40 and the average level of CD40 mRNA between the two groups(P >0.05, both). Conclusions The abnormal expression of CD40L might play an important role in the pathogenesis of SLE, and the level of CD40L might be used as one the indices for active SLE.
