小麦(Triticum aestivum)是世界上种植最广泛的作物,为全球粮食和营养安全做出了重大贡献。小麦富含淀粉、蛋白质、矿物质、B族维生素和生物活性成分,具有很高的营养价值和高适口性。不幸的是,小麦通常被认定为 "八大类 "食物过敏原之一,在过敏体质的人中,它可以启动免疫球蛋白E(IgE)和非IgE介导的食物过敏。 作为最重要的谷物之一,小麦(Triticum aestivum)可引起严重的过敏反应,如面包师哮喘、过敏性鼻炎和特应性皮炎。越来越多的人对中国的小麦产生了过敏;然而,中国只有少数小麦栽培品种筛出具有致敏性。 近期,有研究人员评估了不同中国小麦品种的过敏性,并描述了过敏性鼻炎患者的小麦过敏原特征。 研究人员通过十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)测定了中国小麦的蛋白质(可溶性蛋白、胶质蛋白和谷蛋白)组成,并利用10名小麦过敏患者的阳性血清,通过酶联免疫吸附试验(ELISA)和Western blot测定了免疫球蛋白E(IgE)的结合能力。研究人员还用液相色谱-串联质谱法(LC-MS/MS)鉴定了5条具有显著IgE结合能力的凝胶带。 结果表明,可溶性蛋白
