Abstract

The development of IgG L-glutamic Acid60-L-alanine30-L-tyrosine10 (GAT)-specific plaque-forming cell responses in vitro by virgin and immune (responder X nonresponder)F1 spleen cells after stimulation with responder and nonresponder parental GAT-macrophages (Mphi) was investigated. Virgin F1 spleen cells developed comparable primary responses to both parental GAT-Mphi. By contrast, F1 spleen cells from mice immunized with GAT or responder parental GAT-Mphi developed secondary responses after stimulation with only responder parental GAT-Mphi. Spleen cells from F1 mice immunized with nonresponder parental GAT-Mphi developed secondary responses to these GAT-Mphi, but failed to respond to responder parental GAT-Mphi. These results are discussed in the context of genetic restrictions regulating Mphi-T-cell interactions in secondary antibody responses and the possible expression of Ir-gene function in Mphi.

摘要

研究了经应答者和非应答者亲本谷氨酸-丙氨酸-酪氨酸(GAT)-巨噬细胞(Mphi)刺激后,未致敏和免疫(应答者×非应答者)F1脾细胞在体外产生IgG L-谷氨酸60-L-丙氨酸30-L-酪氨酸10(GAT)特异性空斑形成细胞反应的情况。未致敏的F1脾细胞对两种亲本GAT-Mphi产生了相当的 primary反应。相比之下,用GAT或应答者亲本GAT-Mphi免疫的小鼠的F1脾细胞,仅在应答者亲本GAT-Mphi刺激后产生secondary反应。用非应答者亲本GAT-Mphi免疫的F1小鼠的脾细胞对这些GAT-Mphi产生secondary反应,但对应答者亲本GAT-Mphi无反应。在调节secondary抗体反应中Mphi-T细胞相互作用的遗传限制以及Mphi中Ir基因功能的可能表达的背景下讨论了这些结果。 (注:文中primary和secondary未找到准确对应中文术语,暂保留英文)
