Use of CRISPR in Infection Control

Area of Science:

• Microbiology
• Immunology
• Biotechnology

Background:

• Infectious diseases pose a significant global health threat, causing millions of deaths annually and highlighting the need for advanced diagnostic and therapeutic strategies.
• The COVID-19 pandemic underscored the unpredictable impact and potential of infectious agents, emphasizing the urgency in understanding their pathogenesis and developing effective countermeasures.

Purpose of the Study:

• To explore the potential of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas systems as a tool for combating infectious diseases.
• To highlight the role of CRISPR-Cas technology in advancing diagnostic techniques, treatment strategies, and prevention methods for infectious agents.

Main Methods:

• Review of CRISPR-Cas system classification, focusing on types II, V, and VI for diagnostic applications.
• Analysis of the molecular mechanisms by which CRISPR-Cas systems recognize and degrade foreign DNA.

Main Results:

• CRISPR-Cas systems, functioning as molecular scissors, are integral to bacterial and archaeal adaptive immunity.
• CRISPR systems are classified into 6 types and 22 subtypes, with specific types (II, V, VI) demonstrating utility in diagnostic development.

Conclusions:

• The CRISPR-Cas system presents a powerful platform for developing novel and improved diagnostic tools for infectious diseases.
• Leveraging CRISPR-Cas technology can drive innovation in delivery systems, prevention, and treatment of bacterial, viral, and fungal infections worldwide.
