在类风湿关节炎(RA)的早期检测中,合成聚丝蛋白肽可作为ELISA试验中类风湿特异性自身抗体(抗瓜氨酸肽抗体,ACPA)的抗原。在这项工作中,我们提出了一种肽,它以稳定折叠β-发夹的形式展示了ACPA的结合表位。肽折叠的均匀性被核磁共振波谱证实,并可能导致第一个被提出的抗体结合构象的表位结构。
In the early detection of rheumatoid arthritis (RA) synthetic filaggrin peptides serve as antigens for rheumatoid-specific autoantibodies (anti-citrullinated peptide antibody, ACPA) in ELISA tests. In this work we present a peptide that exhibits the binding epitope of ACPA in the form of a stable folding β-hairpin. The homogeneity of the peptide folding was confirmed by NMR spectroscopy and might lead to the first proposed structure of the antibody-bound conformation of the epitope.
