To test whether the antigen-specific stimulation of low responder-genotype B cells in tetraparental mice is due to a histoincompatibility reaction (allogeneic effect) against these B cells, tetraparental mice were constructed (a) between an Ir-1A low responder to the antigen poly-L(Tyr,Glu)-poly-D,L-Ala--poly-L-Lys. [(T,G)-A--L] and an Ir-1A F1 high responder and (b) between two histoincompatible Ir-lA low responders. In the first case the F1 high responder embryo shares the whole of the H-2 complex, including Ir, with the low responder embryo.
为了检验四亲代小鼠中低反应基因型B细胞的抗原特异性刺激是否归因于针对这些B细胞的组织不相容性反应(同种异体效应),构建了四亲代小鼠:(a) 在对抗原聚-L(酪氨酸,谷氨酸)-聚-D,L-丙氨酸-聚-L-赖氨酸[(T,G)-A-L]呈Ir-1A低反应性的小鼠与Ir-1A F1高反应性小鼠之间;(b) 在两个组织不相容的Ir-1A低反应性小鼠之间。在第一种情况下,F1高反应性胚胎与低反应性胚胎共享整个H-2复合体,包括Ir基因座。
