We examined the effects of the developmental milieu on the capacity of B cells to undergo immune response gene-controlled, T cell-dependent polyclonal proliferation. Although I-Aq poly(Glu60 Ala30 Tyr10)n (GAT)-nonresponder T cells developing in a responder environment become phenotypic GAT-responders, I-Aq B cells remain unresponsive to GAT, even after maturation in a GAT-responder animal. Conversely, (B10.A x B10.Q)F1 ([GAT responder x GAT nonresponder]F1) T cells developing in a B10.Q GAT nonresponder host fail to respond to GAT, but F1 B cells from the same F1 leads to parent chimeras make excellent proliferative responses in the presence of GAT and responder T cells. Thus, by this assay, B cell immune response gene function is genetically determined and is not affected by the developmental milieu.
我们研究了发育环境对B细胞进行免疫应答基因控制的、T细胞依赖性多克隆增殖能力的影响。尽管在应答者环境中发育的I-Aq多聚(Glu60 Ala30 Tyr10)n(GAT)无反应性T细胞会变成表型上的GAT反应者,但I-Aq B细胞即使在GAT反应者动物体内成熟后,对GAT仍无反应。相反,在B10.Q GAT无反应性宿主中发育的(B10.A×B10.Q)F1([GAT反应者×GAT无反应者]F1)T细胞对GAT无反应,但来自同一F1与亲代嵌合体的F1 B细胞在有GAT和反应性T细胞存在的情况下能产生良好的增殖反应。因此,通过该检测方法,B细胞免疫应答基因功能是由基因决定的,不受发育环境的影响。
