自然杀伤(NK)细胞被认为是一种效应细胞,能够介导骨髓移植排斥反应的致死辐射受体。然而,尽管大量的实验证据表明NK细胞可以介导特异性骨髓同种异体移植排斥反应,但骨髓干细胞上存在的拟议靶抗原的性质以及NK细胞可以检测差异的机制仍然是一个谜。NK细胞被认为识别存在于不相容干细胞上的造血组织相容性(Hh-1或Hh)抗原。Hh抗原以非共显性方式表达,其中MHC(小鼠中的H-2)的纯合性是Hh抗原表达的先决条件(班尼特1972)。换句话说,H-2纯合子骨髓移植物被抵抗,而H-2杂合子移植物增殖。已经证明Hh抗原难以分离和表征。然而,通过使用重组小鼠品系对排斥模式的分析,已经显示它们与I类MHC基因不同,并且由H-2的S和D基因座之间的基因编码(Rembecki等,1988)。
Natural killer (NK) cells are believed to be an effector cell capable of mediating bone marrow allograft rejection in lethally irradiated recipients. However, despite a large body of experimental evidence that suggests that NK cells can mediate specific marrow allograft rejection, the nature of the proposed target antigen present on the marrow stem cell and the mechanism by which NK cells can detect disparities has remained an enigma. NK cells are believed to recognize hematopoietic histocompatability (Hh-1 or Hh) antigens present on incompatible stem cells. Hh antigens are expressed in a noncodominant manner in which homozygosity at the MHC (H-2 in the mouse) is a prerequisite for the expression of Hh antigens (Bennett 1972). In other words, H-2 homozygous marrow grafts are resisted and H-2 heterozygous grafts proliferate. Hh antigens have proven to be elusive to isolate and characterize. However, through the analysis of the rejection patterns using recombinant mouse strains they have been shown to be distinct from class I MHC genes, and are encoded for by genes between the S and D locus of H-2 (Rembecki et al. 1988).
