CRISPR-Cas system: from diagnostic tool to potential antiviral treatment

ABSTRACT: This mini review focuses on the diagnosis and treatment of virus diseases using Crisper-Cas technology. The present paper describes various strategies involved in diagnosing diseases using Crispr-Cas-based assays. Additionally, CRISPR-Cas systems offer great potential as new therapeutic tools for treating viral infections including HIV, Influenza, and SARS-CoV-2. There are several major challenges to be overcome before this technology can be applied routinely in clinical settings, such as finding a suitable delivery tool, toxicity, and immunogenicity, as well as off-target effects. This review also discusses ways to deal with the challenges associated with Crisper-Cas technology. KEY POINTS: • Crisper technology is being applied to diagnose infectious and non-infectious diseases. • A new generation of CRISPR-Cas-based assays has been developed which detect pathogens within minutes, providing rapid diagnosis of diseases. • Crispr-Cas tools can be used to combat viral infections, specifically HIV, influenza, and SARS-CoV-2.
