摘要：Previous studies have demonstrated that both the antibody and T-lymphocyte proliferative immune responses to poly(Glu53Lys36Phe11)n (GLphi) are under the control of two major histocompatibility-linked immune response (Ir) genes. One gene, termed Ir-GL phi-alpha, has been mapped to the I-C or I-E subregion of the major histocompatibility complex, while the other, termed Ir-GL phi-beta, has been mapped to the I-A subregion. In this paper we examine the effect of anti-I-region-associated (Ia) antisera on the T-lyphocyte proliferative response to GL phi. Antibodies directed against Ia antigens coded for by genes in either the I-A or I-C subregion were found to inhibit the proliferative response to GLphi. These results suggest that a function mediated by two Ir gene products can be blocked by anit-Ia antisera directed against either one, and thus, that both products are expressed on the cell surface.
