CRISPR-Cas-Mediated Reprogramming Strategies to Overcome Antimicrobial Resistance

Area of Science:

• Microbiology
• Genetics
• Biotechnology

Background:

• Antimicrobial resistance (AMR) is a growing global health crisis, rendering antibiotics ineffective.
• Infections caused by resistant bacteria are increasingly difficult to treat with conventional medicines.

Purpose of the Study:

• To explore CRISPR-Cas technology as a therapeutic strategy against antimicrobial resistance.
• To highlight CRISPR's potential in restoring antibiotic susceptibility and preventing resistance spread.

Main Methods:

• Utilizing CRISPR-Cas systems to target and eliminate bacterial resistance genes.
• Employing CRISPR to disrupt biofilm formation and inhibit bacterial virulence factors.
• Leveraging CRISPR to remove mobile genetic elements, thus suppressing horizontal gene transfer (HGT).

Main Results:

• CRISPR-Cas systems demonstrate the ability to restore antibiotic susceptibility in bacteria.
• Selective bactericidal effects are achieved by eliminating key resistance genes.
• CRISPR effectively inhibits the ecological spread of AMR by targeting mobile genetic elements.

Conclusions:

• CRISPR-based antimicrobials represent a promising next-generation therapy for refractory bacterial infections.
• This technology offers a dual benefit of treating infections and curbing the dissemination of antibiotic resistance.
• Advances in delivery systems and Cas protein engineering are paving the way for clinical translation.
