Abstract

HLA-G is a nonclassic, class I HLA molecule that has important immunomodulatory properties. Previously, we identified HLA-G as an asthma-susceptibility gene and discovered that the risk of asthma in a child was determined by both the child's HLA-G genotype and the mother's affection status. Here we report a SNP in the 3' untranslated region of HLA-G that influences the targeting of three microRNAs (miRNAs) to this gene, and we suggest that allele-specific targeting of these miRNAs accounts, at least in part, for our earlier observations on HLA-G and the risk of asthma.

摘要

HLA-G是一种具有重要免疫调节特性的非经典I类HLA分子。此前,我们将HLA-G鉴定为哮喘易感基因,并发现儿童患哮喘的风险由儿童的HLA-G基因型和母亲的患病状况共同决定。在此我们报告HLA-G 3'非翻译区的一个单核苷酸多态性(SNP),该SNP影响三种微小RNA(miRNA)对该基因的靶向作用,并且我们认为这些miRNA的等位基因特异性靶向作用至少部分解释了我们之前关于HLA-G与哮喘风险的观察结果。
