The clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) systems are RNA-guided sequence-specific prokaryotic antiviral immune systems. In prokaryotes, small RNA molecules guide Cas effector endonucleases to invading foreign genetic elements in a sequence-dependent manner, resulting in DNA cleavage by the endonuclease upon target binding. A rewired CRISPR/Cas9 system can be used for targeted and precise genome editing in eukaryotic cells. CRISPR/Cas has also been harnessed to target human pathogenic viruses as a potential new antiviral strategy. Here, we review recent CRISPR/Cas9-based approaches to combat specific human viruses in humans and discuss challenges that need to be overcome before CRISPR/Cas9 may be used in the clinic as an antiviral strategy.

UI	MeSH Term	Description	Entries
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000072669	Gene Editing	Genetic engineering or molecular biology techniques that involve DNA REPAIR mechanisms for incorporating site-specific modifications into a cell's genome.	Base Editing,Genome Editing,Editing, Base,Editing, Gene,Editing, Genome
D000094704	RNA, Guide, CRISPR-Cas Systems	A component of CRISPR-Cas SYSTEMS. Cas endodeoxyribonucleases assemble with a guide RNA complex, a hybrid of CRISPR RNA (crRNA) and transactivating crRNA (tracrRNA) molecules, to form an active complex that cleaves DNA. crRNA and tracrRNA can be synthetically fused into a single RNA molecule, namely single guide RNA. Synthetic sgRNA is used with CRISPR-Cas SYSTEMS for targeted GENE EDITING.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
