CELL:开发CRISPR技术抗击新冠病毒和流感

2020-05-01 MedSci原创 MedSci原创

目前,SARS-CoV-2病毒正在引起全球冠状病毒病(COVID-19)的大流行,人们急切需要有效的对抗病毒的方法,这些方法可以针对没有有效的疫苗或药物的新兴病毒。

目前,SARS-CoV-2病毒正在引起全球冠状病毒病(COVID-19)的大流行,人们急切需要有效的对抗病毒的方法,这些方法可以针对没有有效的疫苗或药物的新兴病毒。

最近,研究人员开发了一种基于CRISPR-Cas13的策略用于病毒抑制,即PAC-MAN(人体细胞中的预防性抗病毒CRISPR),其可以有效降解人肺上皮细胞中的SARS-CoV-2病毒和活体流感A病毒(IAV)的RNA。

研究人员设计并筛选了CRISPR RNAs(crRNAs),以保守的病毒区域为靶点,确定了针对SARS-CoV-2的功能性crRNAs。这种方法有效地降低了呼吸道上皮细胞中H1N1 IAV的负荷。

此外,生物信息学分析表明,只要6个crRNAs就可以靶向90%以上的冠状病毒。

随着安全有效的呼吸道给药系统的开发,PAC-MAN有可能成为重要的泛冠状病毒抑制策略。
