    • The present invention describes the isolation and purification of histidine-tagged functional portions of intimin (his-tagged intimin or his-intimin), a protein associated with the ability of certain strains of pathogenic bacteria to adhere to epithelial cells. The invention further describes the use of intimin as an antigen to promote a protective immune response. In addition, the invention describes the combination of intimin with one or more other antigens and administration of the combination to promote a protective immune response against intimin and the one or more antigens. One aspect of the invention is the administration of intimin to target specific epithelial cells to promote a protective immune response to intimin proteins. Additional aspects of the invention include the use of intimin or intimin combined with one or more antigens and administration of the combination to target gastrointestinal mucosa and stimulate an immune response. Additionally, the invention describes administration of the combination of intimin combined with drugs, to provide a means for targeted delivery of drugs to specific epithelial cells. Other aspects of the invention include the production of antibodies directed against his-intimin and methods of using such antibodies to provide passive immune protection, and in an assay system.
    • 本发明描述了分泌和纯化组蛋白标记的功能性部分的intimin(his-tagged intimin或his-intimin),一种与某些病原菌菌株粘附于上皮细胞的能力相关的蛋白质。 本发明进一步描述了作为抗原的肠溶蛋白作为促进保护性免疫应答的用途。 此外,本发明描述了肠溶蛋白与一种或多种其它抗原的组合以及组合的施用,以促进针对胰岛素和一种或多种抗原的保护性免疫应答。 本发明的一个方面是给予内膜以靶向特异性上皮细胞以促进对肠溶蛋白的保护性免疫应答。 本发明的另外的方面包括使用与一种或多种抗原组合的肠溶蛋白或肠溶蛋白和给予组合以靶向胃肠粘膜并刺激免疫应答。 另外,本发明描述了与药物组合的联合应用,以提供用于将药物靶向递送到特定上皮细胞的手段。 本发明的其它方面包括产生针对他的肠溶蛋白的抗体以及使用这些抗体提供被动免疫保护的方法,以及在测定系统中。
