CRISPR/Cas9 gene therapy represents a revolutionary approach to treating neurodegenerative diseases by directly editing disease-causing mutations or modulating gene expression. Unlike traditional small-molecule drugs, CRISPR offers the potential for single-dose, durable treatment by addressing the root genetic cause of neurodegeneration.
The CRISPR-Cas9 system utilizes a guide RNA (gRNA) to direct the Cas9 endonuclease to specific genomic loci, creating double-strand breaks that are repaired through:
| Strategy | Mechanism | Applications |
|---|---|---|
| Gene knockout | Disrupt toxic gene expression | HTT, SOD1 |
| Allele-specific editing | Target mutant allele only | HTT, SOD1 |
| Gene correction | Precise HDR-based repair | APP, PSEN1 |
| Gene silencing | Epigenetic repression | Multiple |
| Base editing | Single-nucleotide conversion | Point mutations |
| Prime editing | Precise insertions/deletions | Multiple |
HD is the most tractable target for CRISPR therapy due to its monogenic nature. Strategies include:
Preclinical studies in mouse models have demonstrated that AAV-delivered CRISPR can reduce mHTT expression and improve behavioral outcomes.
Several genetic targets exist:
Gene therapy approaches using AAV vectors to deliver CRISPR components are in preclinical development.
CRISPR applications in AD are more complex due to polygenic nature:
Genetic forms of PD are promising targets:
As of 2026, no CRISPR therapies for neurodegenerative diseases have reached clinical trials. Challenges include:
Several biotechnology companies are actively developing CRISPR platforms for neurological disorders.
