Display of epitopes on virus-like particles (VLPs) is a highly effective technique for enhancing the immunogenicity of antigens that are poorly immunogenic in their native context. VLP-based vaccines can be used to elicit long-lasting, high-titer antibody responses against diverse target antigens, even self-antigens. Most VLP platform-based vaccines are rationally engineered; specific target epitopes or domains are arrayed so that they are displayed at high-valency on the surface of VLPs. In this review, we describe an alternate technique for vaccine discovery using VLPs. This strategy, analogous to filamentous phage display, allows bacteriophage VLP-based vaccines to be identified from a vast library of potential vaccines by affinity selection. This technology integrates epitope discovery and immunization functions into a single platform.
在病毒样颗粒(VLP)上展示表位是一种高效技术,可增强在天然环境中免疫原性较差的抗原的免疫原性。基于VLP的疫苗可用于引发针对多种靶抗原(甚至自身抗原)的持久、高滴度抗体反应。大多数基于VLP平台的疫苗都是经过合理设计的;特定的靶表位或结构域被排列成在VLP表面高价展示。在本综述中,我们描述了一种使用VLP进行疫苗发现的替代技术。这种策略类似于丝状噬菌体展示,通过亲和选择从大量潜在疫苗库中鉴定基于噬菌体VLP的疫苗。该技术将表位发现和免疫功能整合到一个单一平台中。
