YR 2019 UL //www.qdcxjkg.com/content/54/2/1802126.abstract AB人类白细胞抗原（HLA）-G是一种非经典的HLA抑制免疫应答。其表达由单核苷酸多态性（SNP），其与移植结果相关修改。我们的目的是探讨供受者HLA-G的单核苷酸多态性与肺癌transplantation.In这种单中心研究后慢性肺移植物功能障碍（层叠）和死亡率之间的关系，我们在连续345个受援国和捐助国297调查11 HLA-G的SNP第一双侧肺移植。多变量Cox比例风险模型评估死亡和CLAD单核苷酸多态性的关联。Transbronchial biopsies (TBBx) and bronchoalveolar lavage (BAL) samples were examined using quantitative PCR, ELISA and immunofluorescence.Over a median of 4.75 years, 142 patients (41%) developed CLAD; 170 (49%) died. Multivariable analysis revealed donor SNP +3142 (GG+CG versus CC) was associated with increased mortality (hazard ratio 1.78, 95% CI 1.12–2.84; p=0.015). In contrast, five donor SNPs, -201(CC), -716(TT), -56(CC), G*01:03(AA) and 14 bp INDEL, conferred reduced mortality risk. Specific donor–recipient SNP pairings reduced CLAD risk. Predominantly epithelial HLA-G expression was observed on TBBx without rejection. Soluble HLA-G was present in higher concentrations in the BAL samples of patients who later developed CLAD.Specific donor SNPs were associated with mortality risk after lung transplantation, while certain donor–recipient SNP pairings modulated CLAD risk. TBBx demonstrated predominantly epithelial, and therefore presumably donor-derived, HLA-G expression in keeping with these observations. This study is the first to demonstrate an effect of donor HLA-G SNPs on lung transplantation outcome.This largest-ever study on HLA-G SNPs and their relationship to transplant outcomes recognises the role of lung donor HLA-G SNPs on allograft HLA-G expression and outcomes post lung transplantation, a factor previously ignored http://bit.ly/2VZURhm
