MS2 virus-like particles as a versatile platform for multi-disease vaccines: a review

Area of Science:

• Biotechnology
• Immunology
• Virology

Background:

• The MS2 bacteriophage coat protein self-assembles into virus-like particles (VLPs).
• These VLPs are immunogenic and can be engineered for antigen display and RNA packaging.
• VLPs offer a versatile platform for vaccine and diagnostic development.

Purpose of the Study:

• To provide a comprehensive review of MS2 phage coat protein VLP-based vaccine research.
• To highlight the advancements and applications of MS2 VLPs in various immunotherapies.
• To serve as a reference for future VLP vaccine development.

Main Methods:

• Genetic engineering of MS2 coat protein for N-terminal peptide display.
• Fusion of exogenous sequences with the MS2 pac site for selective RNA incorporation.
• Review of existing literature on MS2 VLP applications in vaccine development.

Main Results:

• MS2 VLPs can display antigenic peptides up to 91 amino acids.
• Engineered MS2 VLPs facilitate the selective incorporation of heterologous RNA.
• Demonstrated applications in viral, parasitic, chlamydial, and cancer immunotherapy.

Conclusions:

• MS2 phage coat protein VLPs are a promising platform for vaccine development.
• Their versatility supports applications in diverse therapeutic areas, including cancer immunotherapy.
• Continued research on MS2 VLPs will advance vaccine and diagnostic technologies.
