Figure 2

Representative images of in vivo and ex vivo bioluminescence imaging of the head and brain. (A) Head and (B) brain imaging, of mouse injected with AAV9-SynP-NanoLuc-A53T-a-synuclein without (a) or with (b) fibroin solution. (C,D) Quantitative analysis of bioluminescence signal detected in the head (C) or the brain (D) and expressed in p/sec/cm2/sr. Horizontal lines represent the mean. Each dot represents one head (C) (n = 15, p = 0.0025) or brain (D) (n = 15, p = 0.5) of the injected mouse without fibroin (F−, dark blue) and with fibroin (F+, pink). The bootstrapped mean difference with 95% CI (error bar) is shown on the right side of this graph.
