针头疫苗通过将抗原靶向皮肤驻留树突状细胞并触发皮肤中的局部炎症反应来模拟皮肤病原体入侵的几个方面,这与增强的免疫反应相关。在这里,我们测试了对疫苗递送动力学的控制是否可以通过进一步模拟自然急性感染期间存在的动力学特征来增强免疫力。我们报告了一种方法,用于制造的丝绸/聚(丙烯酸)(PAA)复合微针组成的丝绸尖端支持上的PAA基地。在将微针贴片短暂应用于皮肤时,PAA基质快速溶解以递送蛋白质亚单位疫苗推注,同时还将持久性丝水凝胶储库植入皮肤中,以在1-2周内进行低水平持续皮肤疫苗释放。使用该平台递送具有优化的释放动力学的模型全蛋白疫苗导致相对于传统的基于注射针的胃肠外免疫,抗原特异性T细胞和体液免疫应答增加>10倍。
Microneedle vaccines mimic several aspects of cutaneous pathogen invasion by targeting antigen to skin-resident dendritic cells and triggering local inflammatory responses in the skin, which are correlated with enhanced immune responses. Here we tested whether control over vaccine delivery kinetics can enhance immunity through further mimicry of kinetic profiles present during natural acute infections. We report an approach for the fabrication of silk/poly(acrylic acid) (PAA) composite microneedles composed of a silk tip supported on a PAA base. On brief application of microneedle patches to skin, the PAA bases rapidly dissolved to deliver a protein subunit vaccine bolus, while also implanting persistent silk hydrogel depots into the skin for a low-level sustained cutaneous vaccine release over 1-2 weeks. Use of this platform to deliver a model whole-protein vaccine with optimized release kinetics resulted in >10-fold increases in antigen-specific T-cell and humoral immune responses relative to traditional parenteral needle-based immunization.
