AAV5 Delivery of CRISPR/Cas9 Mediates Genome Editing in the Lungs of Young Rhesus Monkeys

Liang et al., Human Gene Therapy. 2024.

https://pubmed.ncbi.nlm.nih.gov/38767512/

Genome editing in somatic cells and tissues has the potential to provide long-term expression of therapeutic proteins to treat a variety of genetic lung disorders. However, delivering genome-editing machinery to disease-relevant cell types in the lungs of primates has remained a challenge. Investigators of this article are participating in the NIH Somatic Cell Genome Editing Consortium. Herein, they demonstrate that intratracheal administration of a dual adeno-associated virus type 5 vector encoding CRISPR/Cas9 can mediate genome editing in rhesus (male and female) airways. Up to 8% editing was observed in lung lobes, including a housekeeping gene, GAPDH, and a disease-related gene, angiotensin-converting enzyme 2. Using single-nucleus RNA-sequencing, investigators systematically characterized cell types transduced by the vector. Supported by ORIP (P51OD01110, U42OD027094, S10OD028713), NCATS, NCI, and NHLBI.

Promoting Validation and Cross-Phylogenetic Integration in Model Organism Research

Model organisms are essential for biomedical research and therapeutic development, but translation of such research to the clinic is low. The authors summarized discussions from an NIH virtual workshop series, titled “Validation of Animal Models and Tools for Biomedical Research,” held from 2020 to 2021. They described challenges and opportunities for developing and integrating tools and resources and provided suggestions for improving the rigor, validation, reproducibility, and translatability of model organism research.
