摘要

D3a 基因型柯萨奇病毒 A6(CVA6 D3a)是引起中国大陆手足口病(HFMD)的主要病原体。病毒样颗粒(VLP)疫苗是预防手足口病的潜在候选疫苗。本研究采集了使用 CVA6 D3a VLPs 免疫的 BALB/c 雌性小鼠的抗 CVA6 D3a VLPs 血清。比较了不同免疫途径的抗血清对具有代表性的 14-JX2018 株(D3a)和 N4-YN2015 株(D3b)的中和抗体水平。利用癌症研究所(ICR)七天龄小鼠肺部和骨骼肌组织的病理切片和免疫组化结果,监测了抗CVA6 D3a VLP对这些毒株的免疫保护作用。在 7 天大(血清被动免疫保护)和 14 天大(VLPs 主动免疫保护)的新生 ICR 小鼠模型中评估了对不同病毒分支的免疫保护。血清中和抗体水平与免疫次数呈正相关,且针对 14-JX2018 的抗体水平高于针对 N4-YN2015 的抗体水平。此外,腹腔注射的抗体水平明显高于肌肉注射。接种三次的 7 日龄 ICR 小鼠的免疫血清对 CVA6 D3a 14-JX2018 (致死滴度:106.25TCID50)和 CVA6 D3b N4-YN2015 (致死滴度:105.25TCID50)致命攻击的保护率分别为 100%。对于 14 天内完成两次主动免疫的 ICR 小鼠,使用 CVA6 D3a 14-JX2015 (挑战滴度:108.25 TCID50)和 CVA6 D3b N4-YN2015 (挑战滴度:107.25 TCID50)进行挑战,小鼠均能存活。总之,本研究制备的CVA6 D3a VLPs对CVA6 D3a和D3b进化分支病毒都有最佳的保护效果,是一种潜在的CVA6候选疫苗。

Preparation and immunoprotective effects of a virus-like particle candidate vaccine of the dominant epidemic D3 genotype coxsackievirus A6 in China

Coxsackievirus A6 of the D3a genotype (CVA6 D3a) is a primary pathogen causingmainland of China's hand, foot, and mouth disease (HFMD). Viral-like particle (VLP) vaccines represent a potential candidate vaccine to prevent HFMD. This study collected Anti-CVA6 D3a VLPs serum from BALB/c female mice immunized using CVA6 D3a VLPs. The neutralizing antibody levels were compared against the representative 14-JX2018 (D3a) and N4-YN2015 (D3b) strains between the antisera of different immune pathways. The immunoprotective effect of anti-CVA6 D3a VLPs against these strains was monitored using pathological sections and immunohistochemical results of lung and skeletal muscle tissues in seven-day-old Institute of Cancer Research (ICR) mice. Immunological protection against different branches of viruses was evaluated in 7-day-old (serum passive immune protection) and 14-day-old (VLPs active immune protection) neonatal ICR mice models. Serum-neutralizing antibody levels were positively correlated with the number of immunizations and higher against 14-JX2018 than against N4-YN2015. Furthermore, these levels were significantly higher with abdominal injection than intramuscular injection. The immunized serum of 7-day-old ICR mice inoculated three times was 100 % protected against CVA6 D3a 14-JX2018 (lethal titer: 106.25 TCID50) and CVA6 D3b N4-YN2015 (lethal titer: 105.25TCID50) fatal attacks, respectively. For ICR mice that have completed two active immunizations for 14 days, both CVA6 D3a 14-JX2015 (challenge titer: 108.25 TCID50) and CVA6 D3b N4-YN2015 (challenge titer: 107.25 TCID50) were used for the challenge, and the mice were able to survive. Overall, the CVA6 D3a VLPs prepared in this study are a potential vaccine candidate for CVA6, as it has the optimal protective effect against both CVA6 D3a and D3b evolutionary branches viruses.
