Inhibition of Hepatitis B Virus with the Help of CRISPR/Cas9 Technology

Hepatitis B infection caused by hepatitis B virus (HBV) is a serious health issue worldwide. Existing therapeutic strategies hardly eradicate HBV infections, and they fail to attain complete cure. Advanced treatment strategies are urgently needed to successfully terminate further spread of HBV infection and eliminate hidden reservoirs of virus. Recently, a novel RNA-guided gene editing tool, known as the clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9 (CRISPR/Cas9) system, has been established. It facilitates site-specific mutagenesis and reveals a new way to develop applicable techniques for disease treatment, such as extermination of infectious agents like HBV This study highlights the current developments in CRISPR/Cas9 technology and its importance for target-specific inhibition of HBV genome. Benefits, challenges, feasible solutions, and proposed guidelines for forthcoming study in CRISPR/Cas9 are described to highlight the possible cures of and treatments for chronic HBV infection.
