Nowadays, viruses are not only seen as causative agents of viral infectious diseases but also as valuable research materials for various biomedical purposes, including recombinant protein production. When expressed in living or cell-free expression systems, viral structural proteins self-assemble into virus-like particles (VLPs). Mimicking the native form and size of viruses and lacking the genetic material, VLPs are safe and highly immunogenic and thus can be exploited to develop antiviral vaccines. Some vaccines based on VLPs against various infectious pathogens have already been licenced for human use and are available in the commercial market, the latest of which is a VLP-based vaccine to protect against the novel Coronavirus. Despite the success and popularity of VLP subunit vaccines, many more VLPs are still in different stages of design, production, and approval. There are still many challenges that require to be addressed in the future before this surface display system can be widely used as an effective vaccine strategy in combating infectious diseases. In this review, we highlight the use of structural viral proteins to produce VLPs, emphasising their intrinsic properties, structural classification, and main expression host systems. We also compiled the recent scientific literature about VLP-based vaccines to underline the recent advances in their application as a vaccine strategy for preventing and fighting virulent human pathogens. Finally, we presented the key challenges and possible solutions for VLP-based vaccine production.
如今,病毒不仅被视为病毒性传染病的病原体,还被视为各种生物医学用途的有价值的研究材料,包括重组蛋白生产。当在活细胞或无细胞表达系统中表达时,病毒的结构蛋白会自我组装成病毒样颗粒(VLPs)。VLPs 模拟病毒的天然形态和大小,且缺乏遗传物质,因此安全且具有高度免疫原性,可以用于开发抗病毒疫苗。一些基于 VLPs 的针对各种传染性病原体的疫苗已经获得许可用于人类,并在商业市场上销售,最新的一种是基于 VLP 的疫苗,可预防新型冠状病毒。尽管 VLP 亚单位疫苗取得了成功并广受欢迎,但仍有许多 VLPs 处于不同的设计、生产和批准阶段。在这种表面展示系统能够广泛用于对抗传染病的有效疫苗策略之前,仍有许多挑战需要解决。在本文中,我们强调了使用结构病毒蛋白生产 VLPs,重点介绍了它们的固有特性、结构分类和主要表达宿主系统。我们还汇编了最近关于基于 VLP 的疫苗的科学文献,强调了它们作为预防和对抗致命人类病原体的疫苗策略的最新进展。最后,我们提出了基于 VLP 的疫苗生产的关键挑战和可能的解决方案。
