Noroviruses (NoVs) are important pathogens causing epidemic acute gastroenteritis that affects millions of people worldwide. The protruding (P) domain of the NoV capsid protein, the surface antigen of NoV, forms a 24-mer subviral particle called the P particle that is an excellent candidate vaccine against NoVs. The P particles are easily produced in Escherichia coli, highly stable and highly immunogenic. Each P domain has three surface loops that can be used for foreign antigen presentation, making the P particles a useful platform for vaccine development against other infectious diseases. This article summarizes the discovery, structure, development and applications of the P particles as a vaccine against NoVs, as well as a vaccine platform against rotavirus, influenza virus and possibly other pathogens in the future.
诺如病毒(NoV)是导致全球数百万人感染的重要病原体,引发流行性急性肠胃炎。NoV 衣壳蛋白的突出(P)结构域是 NoV 的表面抗原,可形成一种 24 个亚单位的亚病毒颗粒,称为 P 颗粒,是 NoV 的理想候选疫苗。P 颗粒在大肠杆菌中很容易产生,高度稳定且具有高度免疫原性。每个 P 结构域有三个表面环,可用于展示外源抗原,使 P 颗粒成为针对其他传染病的疫苗开发的有用平台。本文总结了 P 颗粒作为 NoV 疫苗的发现、结构、开发和应用,以及作为轮状病毒、流感病毒疫苗平台,未来可能还有其他病原体。
