This review discusses pseudoviruses, which are chimeric viral particles constructed by replacing the envelope glycoproteins of viruses such as human immunodeficiency virus (HIV) or vesicular stomatitis virus (VSV) with those of target viruses, and their advantages in the study of highly pathogenic respiratory viruses. These systems serve as valuable tools for elucidating viral entry mechanisms, screening antiviral drugs, quantitatively assessing virus-neutralizing antibodies, and evaluating vaccine efficacy, while reducing the safety risks associated with live viruses. Despite limitations such as applicability primarily to enveloped viruses, ongoing technological advances continue to improve pseudovirus systems, increasing their utility in vaccine development, antiviral research, and rapid response to emerging infectious diseases.

摘要

This review discusses pseudoviruses, which are chimeric viral particles constructed by replacing the envelope glycoproteins of viruses such as human immunodeficiency virus (HIV) or vesicular stomatitis virus (VSV) with those of target viruses, and their advantages in the study of highly pathogenic respiratory viruses. These systems serve as valuable tools for elucidating viral entry mechanisms, screening antiviral drugs, quantitatively assessing virus-neutralizing antibodies, and evaluating vaccine efficacy, while reducing the safety risks associated with live viruses. Despite limitations such as applicability primarily to enveloped viruses, ongoing technological advances continue to improve pseudovirus systems, increasing their utility in vaccine development, antiviral research, and rapid response to emerging infectious diseases.
