Abstract
Understanding the interactions involved during the immunological synapse between peptide, HLA-E molecules, and TCR is crucial to effectively target protective HLA-E-restricted T-cell responses in humans. Here we describe three techniques based on the generation of MHC-E/peptide complexes (MHC-E generically includes HLA-E-like molecules in human and nonhuman species, while HLA-E specifically refers to human molecules), which allow to investigate MHC-E/peptide binding at the molecular level through binding assays and by using peptide loaded HLA-E tetramers, to detect, isolate, and study peptide-specific HLA-E-restricted human T-cells.
摘要
了解免疫突触中肽、HLA-E 分子和 TCR 之间的相互作用对于有效地靶向人类保护性 HLA-E 限制的 T 细胞反应至关重要。在这里，我们描述了三种基于 MHC-E/肽复合物生成的技术（MHC-E 通常包括人类和非人类物种中的 HLA-E 样分子，而 HLA-E 则专门指人类分子），这些技术允许通过结合测定和使用负载肽的 HLA-E 四聚体在分子水平上研究 MHC-E/肽结合，以检测、分离和研究肽特异性 HLA-E 限制的人类 T 细胞。
