Figure Lengend Snippet: In vivo characterization of the full-length CP040 promoter packaged in the AAVDJ capsid (A) 1 × 10 13 vg/kg of AAVDJ-CP040 -eGFP or vehicle (1x PBS) was injected into the temporal vein of wild-type FVB/NJ neonatal mice (postnatal day 1–2). Necropsies were performed on the mice at six weeks of age, and tissue samples were analyzed for vg content and eGFP transcript levels. (B) Graph presenting vg copy numbers in different organs—cortex, cerebellum, kidneys, spleen, quadriceps, spinal cord, liver and heart. (C) Graph showing the fold change in e GFP transcript levels demonstrating promoter strength in the same organs as in (B). Data represent mean ± SEM, N = 10 mice, ∗∗ p < 0.01, ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001, ns, not significant by one-way ANOVA. (D) Representative IF images showing eGFP expression along with neuronal (NeuN), astrocyte (GFAP), and oligodendrocyte (olig2) markers. Scale bar = 100 uM (E) Cells found to be double-positive for eGFP and one of the other markers (NeuN, GFAP, and olig2) were quantified from the IF images captured. Data presented as mean ± SEM, N = 3 mice, ∗∗∗∗ p < 0.0001 by one-way ANOVA.

Figure Lengend Snippet: Schematic of the overall experiment design for promoter comparison study (A) Viral vectors used in the study. (B) Six-week-old wild-type FVB/NJ mice (C) were injected with AAVDJ-CBA-eGFP, AAVDJ-EF1α-eGFP, AAVDJ-hSYN-eGFP, AAVDJ-CP040-eGFP, or vehicle (1x PBS) through the ICV or IT route. (D and E) Mice were euthanized 9 weeks after AAV injection, and tissue analysis done for viral vg and eGFP transcript and protein analysis for promoter comparison.
