title: Influence of kappa and IgH genes on the T helper cell response to p-azobenzenearsonate tyrosine.
abstract: Immunization of mice with the p-azobenzenearsonate-L-tyrosine conjugate (ABA-Tyr) leads to the activation of ABA-specific T helper cells capable of proliferating in vitro in the presence of the corresponding antigen. This response is under a dual genetic regulation by H-2 and non-H-2 linked genes, and H-2d mice are high-responder. We demonstrate here, using strains congenic to BALB/c for chromosomes (Chr.) 6 or 12 that this T cell response is also influenced by kappa and IgH linked genes. Double congenic mice indicate that Chr.6 and Chr.12 genes have a complementary effect on the response which cannot be predicted solely by the alleles expressed on either of the two chromosomes. In addition, responses in Bailey's inbred recombinant mice allow a possible mapping of the Chr.12 gene at the 5' end of the IgH complex and of the VH-dextran gene family. The mechanisms which may account for the influence of immunoglobulin gene products on the ABA-specific T cell repertoire are discussed.
