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.
