摘要

A novel platform was established for prevention against the SARS-CoV-2 by utilizing a customized cell line. The pseudotyped SARS-CoV-2 was efficienly captured by the overexpressed ACE2 on the cell membrane. The subsequent viral replication and transcription processes could be blocked by the intracellular shRNAs designed as comlement to the viral genome fragments.

Abstract

At present

the coronavirus disease 2019 (COVID-19) pandemic is a global health crisis. Scientists all over the globe are urgently looking forward to an effective solution to prevent the spread of the epidemic and avoid more casualties at an early date. In this study

we establish an effective platform for the prevention of SARS-CoV-2 by combining the neutralization strategy and RNAi technology. To protect normal cells from infection

the customized cells are constructed to stably express viral antigenic receptor ACE2 on the cell membrane. These modified cells are used as bait for inducing the viral entry. The transcription and replication activities of viral genome are intercepted subsequently by the intracellular shRNAs

which are complementary to the viral gene fragments. A pseudotyped virus reconstructed from the HIV lentivirus is utilized as a virus model

by which we validate the feasibility and effectiveness of our strategy

in vitro

. Our work establishes an initial model and lays the foundation for future prevention and treatment of various RNA viruses.
