摘要 目的:探讨CC趋化因子受体7(CCR7)在寻常型银屑病(psoriasisvulgaris,PV)患者外周血T细胞上的表达及其UVB照射对其表达的影响。方法:应用流式细胞术(FCM)和RT-PCR,检测23例PV患者和12例健康人外周血T细胞上CCR7的表达。结果:通过FCM发现PV患者外周血T细胞表面CCR7的表达率为(60.5±10.4)%,显著高于健康人(31.7±2.1)%(P<0.01)。RT-PCR检测显示,PV患者中CCR7基因的表达显著高于健康人对照(P<0.01),并发现200J/m2UVB照射可明显抑制CCR7基因的表达(P<0.01)。结论:PV患者外周血中CCR7+记忆性淋巴细胞数量及分布的异常可能与疾病的炎症维持密切相关。UVB照射的治疗作用可能与影响CCR7基因的表达有关。
