Respiratory syncytial virus (RSV) is a leading cause of respiratory disease in infants, the elderly and immunocompromised individuals. Despite the global burden, there is no licensed vaccine for RSV. Recent advances in the use of nanoparticle technology have provided new opportunities to address some of the limitations of conventional vaccines. Precise control over particle size and surface properties enhance antigen stability and prolong antigen release. Particle size can also be modified to target specific antigen-presenting cells in order to induce specific types of effector T-cell responses. Numerous nanoparticle-based vaccines are currently being evaluated for RSV including inorganic, polymeric and virus-like particle-based formulations. Here, we review the potential advantages of using different nanoparticle formulations in a vaccine for RSV, and discuss many examples of safe, and effective vaccines currently in both preclinical and clinical stages of testing.
呼吸道合胞病毒(RSV)是婴儿、老年人和免疫功能低下者呼吸道疾病的主要病因。尽管其造成了全球负担,但目前尚无获批的RSV疫苗。纳米颗粒技术应用方面的最新进展为解决传统疫苗的一些局限性提供了新机遇。对颗粒大小和表面性质的精确控制可增强抗原稳定性并延长抗原释放时间。颗粒大小也可进行调整以靶向特定的抗原呈递细胞,从而诱导特定类型的效应T细胞反应。目前正在对多种基于纳米颗粒的RSV疫苗进行评估,包括无机、聚合物和基于病毒样颗粒的制剂。在此,我们综述了在RSV疫苗中使用不同纳米颗粒制剂的潜在优势,并讨论了目前处于临床前和临床测试阶段的许多安全有效的疫苗实例。
