In vivo editing with the AAV-BI28 capsid and third generation GFAP-SaCas9 vectors

In vivo editing with the AAV-BI28 capsid and third generation GFAP-SaCas9 vectors. Ai9 mice were injected with BI28:GFAP-SaCas9 (3E11vg/mouse) and BI28:GFAP-NLS-GFP-U6-gRNA(L1- R2) (3E11 vg/mouse) and expression and editing were assessed 4 weeks later. A. Whole brain section and Ai9 locus editing (tdTomato) enabled by AAV-BI28:GFAP-Cas9. B. Efficient co-transduction of BI28:GFAP-SaCas9 and BI28:GFAP-NLS-GFP-gRNA-L1-R2 in cortical astrocytes (S100). C. The graph shows quantification of CNS astrocyte editing measured by the fraction of tdTomato+ area above threshold within the indicated brain regions (mean ± SD, n=6 females and n=4 males). D. Image shows transduction and editing in the liver.
