Abstract

The role of Class I major histocompatibility complex (MHC) molecules in the autologous (AMLR) and allogeneic mixed lymphocyte reactions was investigated by using monoclonal antibodies (MoAb) directed to polymorphic MHC determinants. The AMLR from subjects with the HLA-A2 phenotype was consistently inhibited by the anti-HLA-A2 MoAb, CR11-351, and the inhibition was dose-dependent and complete even at low antibody concentrations. The allogeneic MLR was inhibited by CR11-351 less than 30% when HLA-A2-bearing cells were used either as stimulator or responder cells. Addition of interleukins 1 and/or 2 to the AMLR in the presence of the inhibiting MoAbs did not restore the proliferative response. These studies suggest that Class I MHC polymorphic determinants, or closely related structures, participate in the induction of the AMLR.

摘要

通过使用针对多态性主要组织相容性复合体(MHC)决定簇的单克隆抗体(MoAb),研究了I类主要组织相容性复合体(MHC)分子在自体混合淋巴细胞反应(AMLR)和同种异体混合淋巴细胞反应中的作用。具有HLA - A2表型的受试者的AMLR始终受到抗HLA - A2 MoAb CR11 - 351的抑制,并且这种抑制是剂量依赖性的,即使在低抗体浓度下也是完全抑制。当使用携带HLA - A2的细胞作为刺激细胞或反应细胞时,CR11 - 351对同种异体混合淋巴细胞反应的抑制作用小于30%。在存在抑制性MoAb的情况下,向AMLR中添加白细胞介素1和/或2并不能恢复增殖反应。这些研究表明,I类MHC多态性决定簇或密切相关的结构参与了AMLR的诱导。
