Antigen-stimulated Ly1:Qa1+ cells induce a nonimmune set of T-acceptor cells (surface phenotype Ly123+Qa1+) to participate in the generation of specific suppressive activity. The experiments reported here were designed to test the possibility that the interaction between T-inducer and T-acceptor cells might be governed by genes linked to the Ig locus. We find that inducer:acceptor interactions occur only if the inducer and acceptor T-cell sets are obtained from donor that are identical at the Ig locus and are independent of the Ig locus expressed on the B cells used for assay of T-helper activity. In addition, experiments using inducer and acceptor T cells from the congenic recombinant BAB. 14 strain show that T-T interactions are not governed by Ig-CH genes, per se. These data indicate that T-inducer: T-acceptor interactions are governed by Ig-linked genes that may control expression of VH-like structures on T cells, or control expression of as yet unidentified cell-surface molecules.
抗原刺激的Ly1:Qa1+细胞诱导一组非免疫性的T受体细胞(表面表型为Ly123+Qa1+)参与特异性抑制活性的产生。本文报道的实验旨在测试T诱导细胞与T受体细胞之间的相互作用可能受与Ig基因座连锁的基因调控的可能性。我们发现,只有当诱导细胞和受体T细胞系来自在Ig基因座上相同的供体,并且独立于用于检测T辅助活性的B细胞上表达的Ig基因座时,诱导细胞与受体细胞之间才会发生相互作用。此外,使用来自同源重组BAB.14品系的诱导细胞和受体T细胞进行的实验表明,T-T相互作用本身不受Ig-CH基因的调控。这些数据表明,T诱导细胞与T受体细胞之间的相互作用受与Ig连锁的基因调控,这些基因可能控制T细胞上类VH结构的表达,或控制尚未鉴定的细胞表面分子的表达。
