1、脐血造血干细胞移植的相关免疫分析论文彭新国陈佳荣李占全【关键词】细胞【关键词】脐血干细胞;移植;免疫治疗脐血造血干细胞移植融化疗与免疫治疗于一体,作为血液恶性疾病的治疗手段已获公认,其重要原因就是脐血造血干细胞移植比其他造血干细胞移植具有诸多优点:来源丰富、取材简单;对供、受者HLA相符的要求相对较低;不易受病毒及残留肿瘤细胞的污染;CD3、CD4相对不成熟,GVHD发生率低;NK细胞、LAK细胞较多,GVL发生率低;增殖、自我增殖能力强;骨髓基质细胞多,给造血干细胞提供生长的微环境等。造血干细胞移植
2、的临床快速发展丰富了移植免疫理论,移植免疫的进展亦促进了造血干细胞移植的临床实践。脐血造血干细胞移植亦存在诸多免疫方面的问题,如GVHD、GVL、免疫耐受等发生率虽较低但均有其免疫的机制。为更好地理解、认识及进一步解决这些问题.freelsPA,1997,78:222.HartDNJ.Dendriticcells:Uniqueleukocytepopulationsaryimmuneresponse[J].Blood,1997,1:32453.GuinanEC,GribbenJG,Boussiotis
