Abstract

Graft-vs.-host (GVH) reactions were performed in chicken embryos by intravenous injection of adult chicken blood dilutions, and the result was scored by weighing the spleens as well as by karyological identification of host and donor metaphases. From the frequency of detectable signs of GVH reaction when low doses of donor cells were injected into hosts containing one foreign allele of the B locus it is concluded that 1-2% must be a minimum estimate for the frequency of antigen-sensitive cells of a given specificity in this system. It is not found possible to reconcile the findings with the strictest form of clonal selection which postulates a single receptor specificity per clone of antigen-sensitive cells.

摘要

通过静脉注射成年鸡血液稀释液在鸡胚中进行移植物抗宿主(GVH)反应,并通过称量脾脏以及对宿主和供体中期染色体进行核型鉴定来对结果进行评分。当将低剂量供体细胞注入含有B位点一个外源等位基因的宿主中时,从可检测到的GVH反应迹象的频率得出结论,在该系统中,对于给定特异性的抗原敏感细胞频率,1 - 2%必定是最低估计值。未发现能够将这些发现与克隆选择最严格形式相协调,克隆选择最严格形式假定每个抗原敏感细胞克隆具有单一受体特异性。
