Research Progress and Applications of the Rotavirus Reverse Genetics System

Area of Science:

• Virology
• Molecular Biology
• Infectious Diseases

Background:

• Rotavirus (RV) is a major cause of severe diarrhea in infants and animals globally.
• Research was historically limited by challenges in RV reverse genetics due to its complex genome and poor cell culture adaptation.
• Early helper virus-dependent systems (2006) showed low efficiency.

Purpose of the Study:

• To review the evolution of rotavirus reverse genetics systems.
• To highlight key technological advancements and their impact.
• To discuss applications and future prospects.

Main Methods:

• Narrative review of scientific literature.
• Analysis of technological milestones in rotavirus reverse genetics.
• Discussion of system optimizations, including plasmid-based systems, codon modification, and CRISPR/Cas9 integration.

Main Results:

• A breakthrough in 2017 established the first fully plasmid-based system, eliminating helper viruses.
• Subsequent optimizations have dramatically increased system efficiency for diverse RV strains.
• Reverse genetics is now a viable tool for RV research.

Conclusions:

• Rotavirus reverse genetics has transformed the field, enabling detailed viral gene function analysis.
• This technology is crucial for developing novel vaccines and antiviral drugs.
• Future applications include investigating cross-species transmission and refining therapeutic strategies.
