Abstract:
The emergence and global epidemic of antimicrobial resistance (AMR) poses a serious threat to global public health in recent years. AMR genes are shared between bacterial pathogens mainly via horizontal gene transfer (HGT) on mobile genetic elements (MGEs), thereby accelerating the spread of antimicrobial resistance (AMR) and increasing the burden of drug resistance. There is an urgent need to develop new strategies to control bacterial infections and the spread of antimicrobial resistance. The clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated proteins (Cas) are an RNA-guided adaptive immune system in prokaryotes that recognizes and defends against invasive genetic elements such as phages and plasmids. Because of its specifically target and cleave DNA sequences encoding antibiotic resistance genes, CRISPR/Cas system has been developed into a new gene-editing tool for the prevention and control of bacterial drug resistance. CRISPR-Cas plays a potentially important role in controlling horizontal gene transfer and limiting the spread of antibiotic resistance. In this review, we will introduce the structure and working mechanism of CRISPR-Cas systems, followed by delivery strategies, and then focus on the relationship between antimicrobial resistance and CRISPR-Cas. Moreover, the challenges and prospects of this research field are discussed, thereby providing a reference for the prevention and control of the spread of antibiotic resistance.
Insights
Antimicrobial resistance (AMR) is a global threat. The CRISPR-Cas system offers a novel gene-editing tool to combat AMR by targeting resistance genes and controlling their spread.
Area of Science:
- Microbiology
- Genetics
- Biotechnology
Background:
- Antimicrobial resistance (AMR) is a growing global health crisis, driven by the spread of resistance genes via horizontal gene transfer (HGT) on mobile genetic elements (MGEs).
- Existing strategies to combat AMR are insufficient, necessitating novel approaches to control bacterial infections and resistance dissemination.
Purpose of the Study:
- To review the structure, mechanism, and applications of CRISPR-Cas systems in combating antimicrobial resistance.
- To explore the potential of CRISPR-Cas as a gene-editing tool for controlling HGT and limiting the spread of AMR.
Main Methods:
- Review of existing literature on CRISPR-Cas systems and their role in bacterial immunity and gene editing.
- Analysis of the mechanisms by which CRISPR-Cas targets and cleaves antibiotic resistance genes.
- Discussion of delivery strategies for CRISPR-Cas systems in therapeutic applications.
Main Results:
- CRISPR-Cas systems function as adaptive immune mechanisms in prokaryotes, targeting and cleaving foreign genetic material.
- The specificity of CRISPR-Cas allows for precise targeting of DNA sequences encoding antibiotic resistance genes.
- CRISPR-Cas technology shows promise for controlling HGT and mitigating the spread of AMR.
Conclusions:
- CRISPR-Cas systems represent a powerful and versatile tool for developing new strategies against bacterial infections and antimicrobial resistance.
- Further research into CRISPR-Cas delivery and application is crucial for its effective implementation in clinical settings.
- This technology holds significant potential for controlling horizontal gene transfer and limiting the global burden of drug resistance.
