Figure Lengend Snippet: Figure 2 ｜Postnatal expression of PINK1 and PINK1 knockdown in monkey brain. (A) Western blotting of the monkey cortex from WT and PINK1 mutant (M6) monkeys showing that both BC100-494 and S086D antibodies specifically recognize endogenous PINK1 that is knocked down in M6. (B) Western blot of cortical lysates from monkeys at ages postnatal day 1 (P1), P140, 2 years, and 10 years, and human cortex. Three different PINK1 antibodies (E7B6, BC100-494, and S086D) were used to probe the tissue. (C) E7B6 western blotting analysis of lysates from the cortex of WT monkeys (WT1, P1; WT2, 5 years) and PINK1 mutant monkeys (M7, aborted embryo day 139; M1, P7; M2, P7) and a 5-year-old monkey injected with AAV9-PINK1 gRNA/Cas9 to knock down PINK1 (KD). Knocking down PINK1 can cause neuronal loss in developing and adult monkey brains. (D) AAV9 viral expression of CRISPR/Cas9 to target the PINK1 gene in the prefrontal cortex in the 5-year-old WT adult monkey for 6 weeks resulted in a remarkable loss of neuronal cells, which was evident by the reduced number of NeuN-positive cells. E7B6 immunostaining showed a significant reduction of PINK1 protein in the AAV9- PINK1 gRNA/Cas9-injected region compared with that in the control gRNA/Cas9 injected-region. Arrows indicate AAV-infected cells. Green: PINK1 sgRNA-targeted cells; pink: PINK1 (E7B6) staining; red: NeuN staining; blue: nuclear (DAPI) staining. (E) Glial fibrillary acidic protein (GFAP) immunostaining of the cortex from the same brain sections in D showing that the remaining GFP-positive cells in the AAV9-PINK1 gRNA/Cas9-injected region are GFAP-positive astrocytes. Green: AAV-PINK1 gRNA expression; red: GFAP staining; blue: nuclear staining (DAPI). (F) Quantitative assessment of NeuN-positive neurons in D and GFAP-positive astrocytes in E (n = 5 sections for each group). Data shown as mean ± SEM (n = 5). *P < 0.05, ***P < 0.001 (two-tailed Student’s t-test). In D and E, scale bars: 20 μm. For immunocytochemical analysis, the numbers of cells labeled by specific antibodies per image (40×) from at least three independent experiments were quantified. DAPI: 4′,6-Diamidino-2-phenylindole; ns: not significant; PSD95: postsynaptic density protein-95.
