    • Transcutaneous immunization can deliver antigen to the immune system through the stratum corneum without physical or chemical penetration to the dermis layer of the skin. This delivery system induces an antigen-specific immune response. Use of skin-active adjuvants is preferred. Although perforation of intact skin is not required, superficial penetration or micropenetration of the skin can act as an enhancer; similarly, hydration may enhance the immune response. This system can induce antigen-specific immune effectors after epicutaneous application of a formulation containing one or more antigen and adjuvant. The formulation may initiate processes such as antigen uptake, processing, and presentation; Langerhans cell activation, migration from the skin to other immune organs, and differentiation to mature dendritic cells; contacting antigen with lymphocytes bearing cognate antigen receptors on the cell surface and their stimulation; and combinations thereof. Systemic and/or regional immunity may be induced; immune responses that result in prophylaxis and/or therapeutic treatments are preferred. Antigen and adjuvant activities in the formulation may be found in the same molecule, two or more different molecules dissociated from each other, or multiple molecules in a complex formed by covalent or non-covalent bonds. For antigens and adjuvants which are proteinaceous, they may be provided in the formulation as a polynucleotide for transcutaneous genetic immunization. Besides simple application of a liquid formulation, patches or other medical devices may be used to deliver antigen for immunization.
    • 经皮免疫可以通过角质层将免疫系统的抗原递送到皮肤的真皮层,而不会物理或化学地渗透到真皮层。 该递送系统诱导抗原特异性免疫应答。 优选使用皮肤活性佐剂。 虽然不需要完整皮肤的穿孔,但皮肤的表面渗透或微穿透可以作为增强剂; 类似地,水合可以增强免疫应答。 该系统在表皮施用含有一种或多种抗原和佐剂的制剂后可以诱导抗原特异性免疫效应物。 制剂可以引发诸如抗原摄取,加工和表达的过程; 朗格汉斯细胞活化,从皮肤迁移到其他免疫器官,并分化成成熟树突状细胞; 使抗原与淋巴细胞接触细胞表面的同源抗原受体及其刺激; 及其组合。 可能诱发全身和/或区域免疫; 导致预防和/或治疗性治疗的免疫应答是优选的。 制剂中的抗原和佐剂活性可以在相同的分子中发现,两个或更多个不同的分子彼此离解,或者是通过共价或非共价键形成的复合物中的多个分子。 对于蛋白质的抗原和佐剂,它们可以作为经皮基因免疫的多核苷酸提供在制剂中。 除了液体制剂的简单应用之外,可以使用贴片或其他医疗装置来递送用于免疫的抗原。
