Strengths and limitations of SARS-CoV-2 virus-like particle systems.

Publication date: Jan 01, 2025

Virus-like particles (VLPs) resemble the parent virus but lack the viral genome, providing a safe and efficient platform for the analysis of virus assembly and budding as well as the development of vaccines and drugs. During the COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the formation of SARS-CoV-2 VLPs was investigated as an alternative to authentic virions because the latter requires biosafety level 3 (BSL-3) facilities. This allowed researchers to model its assembly and budding processes, examine the role of mutations in variants of concern, and determine how the structural proteins interact with each other. Also, the absence of viral genome in VLPs circumvents worries of gains in infectivity via mutagenesis. This review summarizes the strengths and limitations of several SARS-CoV-2 VLP systems and details some of the strides that have been made in using these systems to study virus assembly and budding, viral entry, and antibody and vaccine development.
