Pseudotyped Viruses for Coronaviruses.Adv Exp Med Biol. 2023; 1407:133-151.AE
Seven coronaviruses have been identified that can infect humans, four of which usually cause mild symptoms, including HCoV-229E, HCoV-NL63, HCoV-OC43, and HCoV-HKU1, three of which are lethal coronaviruses, named severe acute respiratory syndrome coronavirus, Middle East respiratory syndrome coronavirus, and severe acute respiratory syndrome coronavirus 2. Pseudotyped virus is an important tool in the field of human coronavirus research because it is safe, easy to prepare, easy to detect, and highly modifiable. In addition to the application of pseudotyped viruses in the study of virus infection mechanism, vaccine, and candidate antiviral drug or antibody evaluation and screening, pseudotyped viruses can also be used as an important platform for further application in the prediction of immunogenicity and antigenicity after virus mutation, cross-species transmission prediction, screening, and preparation of vaccine strains with better broad spectrum and antigenicity. Meanwhile, as clinical trials of various types of vaccines and post-clinical studies are also being carried out one after another, the establishment of a high-throughput and fully automated detection platform based on SARS-CoV-2 pseudotyped virus to further reduce the cost of detection and manual intervention and improve the efficiency of large-scale detection is also a demand for the development of SARS-CoV-2 pseudotyped virus.
