2019 年冠状病毒病 (COVID-19) 是由人类感染严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 引起的。尽管出现了几种新的疫苗,但仍然没有可验证的专门针对该病毒的治疗方法。在这里,我们使用新型脂质纳米颗粒(LNP)递送系统提出了一种针对 SARS-CoV-2 感染的高效小干扰 RNA(siRNA)疗法。筛选了多种针对 SARS-CoV-2 病毒高度保守区域的 siRNA,并出现了三种候选 siRNA,它们单独或相互组合可有效抑制病毒 90% 以上。我们同时开发和筛选了两种新型 LNP 制剂,用于将这些候选 siRNA 疗法输送到肺部,而肺部是一个在 SARS-CoV-2 感染期间遭受巨大损害的器官。将 siRNA 封装在这些 LNP 中,然后进行体内注射,证明了对肺部病毒的强大抑制,并对治疗的小鼠具有明显的生存优势。我们的 LNP-siRNA 方法具有可扩展性,可以在人类出现 SARS-CoV-2 感染的第一个迹象时进行施用。我们认为,siRNA-LNP 治疗方法作为当前疫苗策略的辅助疗法,在治疗 COVID-19 疾病方面可能非常有用。这里描述的是第一个报道的基于脂质纳米颗粒递送小干扰 RNA 的治疗方法,其目标是抑制 SARS-COV-2 基因组,作为治疗 COVID-19 的方法。
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in humans. Despite several emerging vaccines, there remains no verifiable therapeutic targeted specifically to the virus. Here we present a highly effective small interfering RNA (siRNA) therapeutic against SARS-CoV-2 infection using a novel lipid nanoparticle (LNP) delivery system. Multiple siRNAs targeting highly conserved regions of the SARS-CoV-2 virus were screened, and three candidate siRNAs emerged that effectively inhibit the virus by greater than 90% either alone or in combination with one another. We simultaneously developed and screened two novel LNP formulations for the delivery of these candidate siRNA therapeutics to the lungs, an organ that incurs immense damage during SARS-CoV-2 infection. Encapsulation of siRNAs in these LNPs followed by in vivo injection demonstrated robust repression of virus in the lungs and a pronounced survival advantage to the treated mice. Our LNP-siRNA approaches are scalable and can be administered upon the first sign of SARS-CoV-2 infection in humans. We suggest that an siRNA-LNP therapeutic approach could prove highly useful in treating COVID-19 disease as an adjunctive therapy to current vaccine strategies. Described here is the first reported therapeutic based on lipid-nanoparticle delivery of small interfering RNAs targeted to inhibit the genome of SARS-COV-2 as a treatment for COVID-19.
