HLA class I-transgenic mice express HLA antigen on their tissues and establish self-tolerance to the expressed monomorphic and polymorphic determinants. When challenged with skin grafts and lymphoid cells of a second HLA-transgenic mouse expressing a different HLA molecule, a specific immune response is elicited that is focused on the determinants specified by the allelic HLA differences between donor and recipient transgenic mice. In the studies described, this has led to the production of a number of monoclonal antibodies with specificity for the HLA-Cw3 and HLA-B7 crossreactive groups of class I antigens. These results indicate that immunization of appropriate transgenic strains of mice with murine cells expressing a different HLA allelic transgene should permit the generation of monoclonal antibodies of narrow specificity against virtually any polymorphic epitope on HLA antigens.
HLA I类转基因小鼠在其组织上表达HLA抗原,并对所表达的单态性和多态性决定簇建立自身耐受性。当用表达不同HLA分子的第二只HLA转基因小鼠的皮肤移植物和淋巴细胞进行攻击时,会引发特异性免疫反应,该反应集中于供体和受体转基因小鼠之间等位基因HLA差异所指定的决定簇。在所描述的研究中,这已导致产生了许多对I类抗原的HLA-Cw3和HLA-B7交叉反应组具有特异性的单克隆抗体。这些结果表明,用表达不同HLA等位基因转基因的鼠细胞免疫适当的转基因小鼠品系,应该能够产生针对HLA抗原上几乎任何多态性表位的窄特异性单克隆抗体。
