摘要 目的 探讨杀伤细胞免疫球蛋白样受体/人类白细胞抗原(KIR/HLA)受配体模式对接受单倍型造血干细胞移植患者预后的影响.方法 采用序列特异性引物聚合酶链反应(PCR-SSP)方法,对5对HLA半相合供/受者移植前进行KIR与HLA分型,同时分析KIR/HLA的受配体模式.结果 5例受者均获得完全、持久供者干细胞植入.中性粒细胞计数≥0.5×109/L的中位时间为13d,血小板计数≥20×109/L的中位时间为18d.1例KIR2DS1阳性患者造血重建较快、急性移植物抗宿主病发生率较低、移植后感染较轻.结论 在单倍型造血干细胞移植中,分析供受者KIR及其配体可为供者优化选择提供分子生物学依据.
