摘要 目的:探讨特发性血小板减少性紫癜(ITP)患者外周血淋巴细胞及血小板上CD 40、CD 40L和血浆sCD 40、sCD 40L的表达及意义。方法:采用免疫荧光标记和流式细胞术检测37例ITP患者和30例健康志愿者外周血CD 19+CD 40+细胞和CD 3+CD 40L+细胞分别占淋巴细胞的比例及血小板膜表面CD 40和CD 40L水平,采用EL ISA检测血浆sCD 40和sCD 40L水平。结果:与健康志愿者相比,急性ITP患者外周血CD 19+CD 40+细胞和CD 3+CD 40L+细胞均增多(P<0.05),血浆sCD 40水平显著降低(P<0.01),sCD 40L水平显著增高(P<0.01),血小板膜表面CD 40L表达增多(P<0.05),慢性ITP患者CD 3+CD 40L+细胞显著增多(P<0.01);与治疗前比较,急性ITP患者治疗缓解后血浆sCD 40水平显著增高(P<0.01),sCD 40L水平显著降低(P<0.01),CD 3+CD 40L+细胞及血小板膜CD 40L表达均降低。结论:ITP患者CD 40/CD 40L共刺激分子存在异常,可能与ITP发病密切相关,治疗缓解后CD 40/CD 40L恢复正常。
