Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) gene editing offers precise disease treatment. Effective in vivo delivery of CRISPR/Cas9 systems remains a key challenge for future therapeutic development.
Area of Science:
- Biotechnology
- Genetics
- Molecular Biology
Background:
- CRISPR/Cas9 gene editing technology shows great promise for permanent disease correction and gene disruption.
- Development of efficient Cas9 variants addresses complex genomic alterations in diseases.
- Current limitations exist in the effective in vivo delivery of CRISPR systems to target cells.
Purpose of the Study:
- To review current developments in CRISPR/Cas9 gene editing for disease treatment.
- To examine gene-editing types, delivery vectors, and disease characteristics relevant to CRISPR applications.
- To summarize clinical trial successes and identify challenges in CRISPR/Cas9 targeted delivery.
Main Methods:
- Review of CRISPR/Cas9 gene-editing technologies and their variants.
- Analysis of nonviral delivery vectors with target recognition capabilities.
- Examination of disease-specific factors for targeted delivery and gene editing strategies.
Main Results:
- CRISPR/Cas9 technology enables precise correction of mutations and disruption of disease genes.
- Nonviral vectors with targeting functions are a focus for future in vivo delivery research.
- Disease characteristics can inform targeted delivery and gene editing approaches.
Conclusions:
- Effective in vivo delivery remains a significant hurdle for CRISPR/Cas9-based disease therapies.
- Tailoring gene-editing methods and delivery vectors to specific diseases is crucial.
- Further research is needed to overcome challenges in targeted delivery and clinical application of CRISPR/Cas9.
