ABSTRACT
Antigen-stimulated Ly1Qa1+ 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 induceracceptor 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.
