有效和安全的疫苗是防治传染病的宝贵工具。导致2019年冠状病毒病大流行的严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)的快速传播凸显了开发快速有效疫苗开发方法的必要性。DNA折纸纳米颗粒(DNA-NPs)提出了多个抗原在规定的纳米级模式,最近出现了作为一个安全,有效,易于扩展的替代合理设计的疫苗。在这里,我们利用这些DNA-NP的独特性质,并证明了在DNA-NP上沿着CpG佐剂的SARS-CoV-2受体结合结构域(RBD)的重建三聚体的10个拷贝的精确图案化能够在小鼠模型中引发针对SARS-CoV-2的强大保护性免疫。我们的研究结果表明,我们的DNA-NP为基础的方法开发安全有效的纳米疫苗,以对抗感染性疾病的病毒挑战的背景下,延长抗体反应和有效的保护的潜力。基于DNA折纸纳米颗粒的SARS-Cov-2疫苗共递送病毒RBD抗原和CpG佐剂,并在小鼠模型中激发针对病毒的强大保护性免疫。
Effective and safe vaccines are invaluable tools in the arsenal to fight infectious diseases. The rapid spreading of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the coronavirus disease 2019 pandemic has highlighted the need to develop methods for rapid and efficient vaccine development. DNA origami nanoparticles (DNA-NPs) presenting multiple antigens in prescribed nanoscale patterns have recently emerged as a safe, efficient, and easily scalable alternative for rational design of vaccines. Here, we are leveraging the unique properties of these DNA-NPs and demonstrate that precisely patterning ten copies of a reconstituted trimer of the receptor binding domain (RBD) of SARS-CoV-2 along with CpG adjuvants on the DNA-NPs is able to elicit a robust protective immunity against SARS-CoV-2 in a mouse model. Our results demonstrate the potential of our DNA-NP-based approach for developing safe and effective nanovaccines against infectious diseases with prolonged antibody response and effective protection in the context of a viral challenge. A DNA origami nanoparticle-based vaccine against SARS-Cov-2 co-delivers viral RBD antigen and CpG adjuvant and elicits a robust protective immunity against the virus in a mouse model.
