    • Provided is a mAb-based method for the detection of T cell stimulatory epitopes known to be involved in CD. The method has many advantages compared to the existing methods for the detection of gluten since it is the first method that can; (i) detect T cell stimulatory epitopes of gluten; (ii) detect the epitopes separately, (iii) detect T cell stimulatory epitopes present on gliadin and glutenin homologues present in other cereals also known to be involved in CD; and (iv) detect T cell stimulatory epitopes on both intact proteins and small protein fragments. The new method is a valuable tool in the screening of basic ingredients, semi manufactured ingredients and food products that are intended to be used in the gluten free diet of CD patients. Moreover the new method can also be used for the screening of cereals and different wheat varieties for the level of toxicity for CD patients. Thereby the method can help in the selection of cereals and wheat varieties with low toxicity which might form the basis for future breeding programs. In the future these cereals will be used for the production of safe food for CD patients.
    • 提供了用于检测已知参与CD的T细胞刺激性表位的基于mAb的方法。 与现有的麸质检测方法相比,该方法具有许多优点,因为它是第一种方法; (i)检测谷蛋白的T细胞刺激性表位; (ii)分别检测表位,(iii)检测存在于已知参与CD的其他谷物中的麦醇溶蛋白和谷蛋白同源物上存在的T细胞刺激性表位; 和(iv)检测完整蛋白质和小蛋白质片段上的T细胞刺激性表位。 这种新方法是筛选旨在用于CD患者无麸质饮食的基本成分,半成品成分和食品的有用工具。 此外,该新方法还可用于筛选谷类和不同小麦品种的CD病毒毒性水平。 因此,该方法可以帮助选择低毒的谷类和小麦品种,这可能构成未来育种计划的基础。 未来这些谷物将用于为CD患者生产安全食品。

    • The present invention identifies novel epitopes from the insulin B chain which is embodied in methods and means for diagnostics and treatment of type 1 diabetes. The epitopes were found in a peptide comprising a fragment of the human insulin B chain. Using HLA-A2 tetramers having the peptide of the invention cytotoxic T-cells were found in peripheral blood cells samples from healthy individuals. The invention demonstrates that these autoreactive CTL directed against insulin B chain are able to destroy insulin producing beta-cells. Moreover, a significant proportion of cytotoxic T-cells from islet transplant recipients with recurrent autoimmunity and loss of insulin production recognized this peptide or analogue thereof. The peptide has a high affinity for the HLA-A2 allele, in particular HLA-A*0201. Based on the novel epitopes according to the invention, diagnostic and therapeutic methods and medicaments for the prevention or treatment of type 1 diabetes are provided.
    • 本发明鉴定来自胰岛素B链的新表位,其体现在用于诊断和治疗1型糖尿病的方法和手段中。 在包含人胰岛素B链的片段的肽中发现表位。 在来自健康个体的外周血细胞样品中发现使用具有本发明的肽细胞毒性T细胞的HLA-A2四聚体。 本发明证明这些针对胰岛素B链的自身反应性CTL能够破坏产生胰岛素的β细胞。 此外,来自具有复发性自身免疫和胰岛素生成丧失的胰岛移植受体的相当大比例的细胞毒性T细胞识别该肽或其类似物。 该肽对HLA-A2等位基因,特别是HLA-A * 0201具有高亲和力。 基于本发明的新型表位,提供了用于预防或治疗1型糖尿病的诊断和治疗方法和药物。
