目的研究外表面蛋白A(OspA)和人淋巴细胞功能相关抗原1(hLFA-1)多肽与5种主要组织相容性复合物(MHC)分子的结合。在难治性莱姆关节炎患者中,HLA-DRB 1 * 结合与5种MHC分子的频率相关。0401分子与OspA 163 - 175和hLFA-1αL330- 342结合良好。尽管结合的幅度较小,但DRB 1 *0404分子也显示出两种肽的结合。DRB 1 *0101分子与OspA 163 - 175结合良好,但与hLFA-1αL330- 342结合较弱; DRB 1 *0801或 *1101分子与两种肽结合较弱(如果有的话)。OspA 163 - 175结合强度与耐药关节炎患者DRB 1等位基因频率相关,而hLFA-1αL330- 342结合强度仅与DRB*04等位基因相关。结论OspA 163 - 175是引发抗生素耐药莱姆关节炎的关键表位。然而,DRB*0101分子不能结合hLFA-1αL330- 342,表明该肽可能不是相关的自身抗原,至少在DRB 1 *0101阳性患者中是如此。
ObjectiveTo assess the binding of outer surface protein A (OspA) and human lymphocyte function–associated antigen 1 (hLFA‐1) peptides to 5 major histocompatibility complex (MHC) molecules.MethodsPeptide binding to the MHC molecules was determined by in vitro binding assays, and binding was correlated with the frequencies of the 5 MHC molecules in patients with treatment‐resistant Lyme arthritis.ResultsThe HLA–DRB1*0401 molecule bound both OspA163–175and hLFA‐1αL330–342well. Although the magnitude of the binding was less, the DRB1*0404 molecule also showed binding of both peptides. The DRB1*0101 molecule bound OspA163–175well, but hLFA‐1αL330–342only weakly; the DRB1*0801 or *1101 molecule bound both peptides weakly, if at all. The magnitude of OspA163–175binding correlated well with the frequencies of the DRB1 alleles in patients with treatment‐resistant arthritis, but the binding of hLFA‐1αL330–342showed only an association with the DRB*04 alleles.ConclusionThese correlations support the hypothesis that OspA163–175is the critical epitope in triggering antibiotic treatment–resistant Lyme arthritis. However, the inability of the DRB*0101 molecule to bind hLFA‐1αL330–342suggests that this peptide may not be a relevant autoantigen, at least in DRB1*0101‐positive patients.
