Abstract

Cryptococcus neoformans is considered a critical fungal pathogen by the World Health Organization and developing a vaccine for cryptococcosis is a top priority. Here, we employed mRNAs encoding an antigen(s) packaged in lipid nanoparticles (LNPs) to develop vaccines for cryptococcosis. Remarkably, when coupled with capsule adjuvant, vaccination with CDA1-LNPs protected the vast majority of mice from the otherwise lethal cryptococcosis. These results support the promise of mRNA-LNP vaccines against fungal diseases.

世界卫生组织认为新生隐球菌是一种重要的真菌病原体,开发隐球菌病疫苗是当务之急。在这里,我们采用了将编码抗原的 mRNA 包装在脂质纳米颗粒(LNPs)中来开发隐球菌病疫苗。值得注意的是,当与胶囊佐剂结合使用时,CDA1-LNPs 疫苗能保护绝大多数小鼠免于致命的隐球菌病。这些结果为 mRNA-LNP 疫苗防治真菌疾病带来了希望。
