SARS-CoV-2 gene coding capacity enables virus engineering platform for heterologous gene expression

Summary

This article presents research on leveraging SARS-CoV-2's unique gene expression strategy and genomic flexibility to create a platform for expressing heterologous genes. By expanding the virus's gene coding capacity without altering its natural genomic architecture (such as through gene deletion), the researchers established an alternative engineering platform. The work highlights the genomic flexibility of orthocoronaviruses, particularly the presence of accessory genes that vary among different viruses, and demonstrates practical applications for research, prophylactic, and therapeutic purposes.
