美国麻省理工学院研究团队研制出一种新型纳米递送颗粒，可显著提升信使核糖核酸（mRNA）疫苗效 力，因此有望大幅降低单剂疫苗成本。相关成果发表于新一期《自然·纳米技术》杂志。 最新研制的AMG1541脂质纳米颗粒展现出两大优势：一是显著提升"内体释放"效率——当颗粒进入细 胞后，能更快速突破内体隔室的束缚，释放mRNA发挥作用；二是酯基尾部设计使颗粒完成使命后迅速 降解，既加速体内清除过程，又可降低副作用风险。 为验证实际效果，团队以mRNA流感疫苗为模型，将新型颗粒与莫德纳新冠疫苗采用的SM-102脂质进 行对比。试验证实，新型颗粒仅需百分之一剂量即可引发同等水平的抗体反应。 该项技术不仅有助于开发更精准匹配当年流行毒株的流感疫苗，更为艾滋病等重大传染病的防控开辟了 新的技术路径。 （文章来源：科技日报） 动物试验显示，采用新型纳米颗粒递送的mRNA流感疫苗，仅需传统疫苗百分之一的剂量，即可在小鼠 体内激发同等强度的免疫反应。值得注意的是，该颗粒不仅适用于流感疫苗，也有望用于新冠、艾滋病 等多种传染病的防控体系。 为了让mRNA在体内输送过程中保持稳定，通常将疫苗包裹在脂质纳米颗粒中。这些微脂球体既能护送 m ...
