Antibodies specific for the immunizing Ag (Ab1) (Id+ Ag+) and Ab3 (Id+ Ag+ or Id+ Ag-) of the (Glu60 Tyr10 Ala30) (GAT) idiotypic cascade express similar pGAT public determinants in BALB/c and C57BL/6 strains. These determinants have been shown to be dependent upon both VH and Vkappa encoded segments. The VH of the BALB/c Ab1 (germ-line gene H10) and that of the C57BL/6 Ab1 (germ-line gene V186-2) are only 75% homologous, whereas VK are much more conserved. C57BL/6 mice were immunized with BALB/c Ab2 (anti-idiotypic) antibodies and monoclonal Ab3 were derived after fusion of immunized spleen cells with the nonsecreting hybridoma cell line Sp/2.0-Ag. From 13 cell lines, five clones (four Id+ Ag- and one Id+ Ag+) were isolated and the mRNA V regions sequenced. Immunization with BALB/c anti-idiotypes elicits expression of the same or closely related C57BL/6 VH and Vkappa genes as when C57BL/6 mice were immunized with GAT, although functional VH BALB/c equivalents have been isolated in the B6 strain. Our results suggest that manipulation of the repertoire via antigenic or idiotypic stimulation both lead to the expression of different genes in different strains. They further confirm that the immune system is largely degenerate, for both idiotype expression and Ag recognition.
