    • Conjugated peptides include a first peptide component which is an antigen associated with autoimmune disease, allergy, asthma or transplantation rejection and binds to an antigen-specific receptor on a T cell, and a second peptide component which corresponds to an "antigen presenting molecule", namely, a peptide binding to a T cell surface receptor, which would normally promote T cell activation when the first peptide is bound to its antigen-specific T cell receptor. However, in this invention, the second peptide component has an amino acid sequence which is a modification of an antigen presenting T cell binding peptide, such modification blocking or inhibiting the engagement of receptor sites on the T cell surface (other than the antigen-specific T cell receptor). As a result, T cell activation is prevented, and is directed through antigen-specific T cell receptor occupation, without T cell activation, leading to antigen-specific T cell anergy and cell death. Administration of the conjugated peptide to an animal will provide protection against disease associated with the first peptide component, resulting from the elimination of the T cells bearing the antigen-specific receptors for that antigenic peptide. The conjugated peptides of this invention provide antigen-specific protection without impairing the immune response to other antigens.
    • 共轭肽包括与自身免疫疾病,变态反应,哮喘或移植排斥相关的抗原的第一肽组分和与T细胞上的抗原特异性受体结合的第一肽组分和对应于“抗原呈递分子”的第二肽组分, 即结合T细胞表面受体的肽,当第一个肽与其抗原特异性T细胞受体结合时,其通常促进T细胞活化。 然而,在本发明中,第二肽成分具有作为抗原呈递T细胞结合肽的修饰的氨基酸序列,这种修饰阻断或抑制T细胞表面上的受体位点(除抗原特异性 T细胞受体)。 结果,T细胞激活被阻止,并且通过抗原特异性T细胞受体占据被引导,没有T细胞活化,导致抗原特异性T细胞无反应性和细胞死亡。 将缀合肽施用于动物将提供针对与第一种肽组分相关的疾病的保护,这是由于消除具有该抗原肽的抗原特异性受体的T细胞而产生的。 本发明的缀合肽提供抗原特异性保护,而不损害对其他抗原的免疫应答。

    • The present invention relates to the use of milk and milk-related products as a carrier or delivery vehicle for allergens in the process of oral tolerance induction. In one preferred embodiment, infants are subjected to primary oral tolerance through provision of a cocktail of allergens in infant milk formula. In another preferred embodiment, secondary oral tolerances is induced through administration of one or more allergens mixed with milk to a mammal of any age. The benefits of using milk as a carrier are evident from experiments which show that ovalbumin tolerance can effectively be induced in an allergic dog model at low dosages. A possible explanation for this is that milk stabilizes the allergen and presents it to the immune system in such a way that it is very potent in effecting a tolerance response.
    • 本发明涉及在口服耐受诱导过程中使用乳和乳相关产品作为过敏原的载体或递送载体。 在一个优选的实施方案中,通过在婴儿奶粉配方中提供过敏原的混合物,对婴儿进行初步口服耐受。 在另一个优选的实施方案中,通过向任何年龄的哺乳动物施用与乳混合的一种或多种过敏原诱导次要口服耐受性。 使用牛奶作为载体的好处从实验中可以看出,这表明卵白蛋白耐受能够以低剂量在过敏性狗模型中有效诱导。 这样做的一个可能的解释是,牛奶可以稳定变应原,并将其呈递给免疫系统,使其在实现耐受反应方面非常有效。
