摘要 目的研究系统性红斑狼疮患者(SLE)及健康人外周血Vα24+Vβ11+、CD161+Vα24+NKT细胞的数量变化。方法采用流式细胞仪检测30例SLE患者和30例健康对照组Vα24+Vβ11+、CD161+Vα24+NKT细胞数量并与临床指标进行相关分析。结果SLE患者外周血Vα24+Vβ11+、CD161+Vα24+NKT细胞显著低于正常对照组(P<0.05);SLE患者Vα24+Vβ11+、CD161+Vα24+NKT细胞与C3,C4呈正相关关系(P<0.01),与SLE疾病活动性指数(SLEDIA)、红细胞沉降率(ESR)呈负相关关系(P<0.05)。结论CD161+Vα24+NKT显著低于正常对照组,表明SLE患者血中活化的NKT细胞数量减少,SLE患者外周血Vα24+Vβ11+、CD161+Vα24+NKT细胞可能参与SLE的发病过程且与病情活动有关。 Objective To explore the changes of the amount and function of Vα24+Vβ11+,CD161+Vα24+NKT cells in the peripheral blood of systemic lupus erythematosus(SLE)patients. Methods The amount of Vα24+Vβ11+,CD161+Vα24+NKT cells in the peripheral blood of 30 SLE cases and 30 healthy persons were detected by flow cytometry. Results Vα24+Vβ11+,CD161+Vα24+NKT cells in the peripheral blood of SLE patients were significantly lower than that of normal control(P 〈 0.05). Vα24+Vβ11+ and CD161+Vα24+NKT cells in the peripheral blood of SLE patients positively correlated with the level of the complement (C3, C4 ) and negatively correlated with SLE disease ac- tivity index (SLEDIA) and ESR. Conclusion Activated NKT cells decreased in the peripheral blood of SLE patients. Vα24+Vβ11+ and CD161+Vα24+NKT cells might be involved in the pathogenesis and development of SLE.
