Abstract: | The immune response patterns of inbred and congenic strains of mice against terpolymers poly(glu57lys38ala5) and poly(glu54lys36ala10) have been studied. Initial recognition of the polymers is ascribed to ‘GA’ receptors (Ir-GA gene product) on T cells of mice ofH-2 haplotypes,a,b,f,k ands, and ‘GL’ receptors (Ir-GL gene product) of mice ofH-2 p,H-2 q andH-2 j haplotypes, and to GA and/or GL receptors of mice ofH- 2d andH- 2r haplotypes. The specificity of the antibody is directed predominantly against GL. The inability to elicit antibody with GA specificity has been ascribed to the lack of significant concentrations of GA sequences in the polymers to interact with appropriate receptors on B cells. The weakest responders were mice of H-2b haplotype. F1 hybrids (responders×nonresponders) were all responders demonstrating the dominant character of responsiveness. Wide variations in antibody levels produced among strains of mice of theH-2 k andH-2 b haplotypes are ascribed to genes not linked toH-2. |
