    • The present invention provides methods and compositions for treating or preventing allergic responses, particularly anaphylactic allergic responses, in subjects who are allergic to allergens or susceptible to allergies. Methods of the present invention utilize administration of microorganisms to subjects, where the microorganisms produce allergens and protect the subjects from exposure to the allergens until phagocytosed by antigen-presenting cells. Particularly preferred microorganisms are gram-negative bacteria, gram-positive bacteria, and yeast. Particularly preferred allergens are proteins found in foods, venoms, drugs and latex that elicit allergic reactions and anaphylactic allergic reactions in individuals who are allergic to the proteins or are susceptible to allergies to the proteins. The proteins may also be modified to reduce the ability of the proteins to bind and crosslink IgE antibodies and thereby reduce the risk of eliciting anaphylaxis without affecting T-cell mediated Th1-type immunity.
    • 本发明提供了用于治疗或预防对过敏原过敏或容易过敏的受试者的过敏反应,特别是过敏性过敏反应的方法和组合物。 本发明的方法利用对微生物施用微生物,其中微生物产生变应原并保护受试者不被暴露于变应原,直到被抗原呈递细胞吞噬。 特别优选的微生物是革兰氏阴性细菌,革兰氏阳性菌和酵母。 特别优选的过敏原是在食物,毒液,药物和胶乳中发现的蛋白质,其对于对蛋白质过敏或易受蛋白质过敏的个体引起过敏反应和过敏性过敏反应。 也可以修饰蛋白质以降低蛋白质结合和交联IgE抗体的能力,从而降低引发过敏反应的风险,而不影响T细胞介导的Th1型免疫。
