pSer129-αSyn immunoblotting and Thioflavin S/αSyn staining on F2 mCherry-αSyn 5 dpf larvae. (A) Western blot analysis showed the presence of high molecular weight pSer129-αSyn bands in the total protein extracted from F2 mCherry-αSyn pools of 20 larvae at 5 dpf. (B) Graph shows relative densitometric quantification relative to β-actin of the bands in the upper red box. Boxplots represent the distribution of 75 %, 50 %, and 25 % of the values, with experiments done in triplicate, n = 5, and samples loaded in double, Mann-Whitney U test, **** p < 0.0001. (C) Confocal images of double fluorescent immunolabelling with anti-pS129-αSyn (AF488) and anti-αSyn (2A7) (Cy5) antibodies (Table 2) on 5 dpf larval sagittal sections of control and F2 mCherry-αSyn midbrains. Non-specific signal in green is marked with a star. Scalebar 20 μm. (D) Orthogonal projection of 4× crop from image C, showing accumulation of anti-pS129-αSyn positive inclusions (arrows). Scalebar 20 μm. (E) Confocal images of the Thioflavin S-positive signal, indicative of fibrillary aggregation, in co-localization with αSyn (2A7) immunopositive labeling in the lateral medulla oblongata (MO) of transgenic and control larvae at 5 dpf. Please note that an asterisk is located nearby non-specific signals, while yellow arrows indicate Thioflavin-S/ αSyn-positive inclusions. Scalebar 10 μm. (F) Orthogonal projection of the x-axis (green rectangle) and y-axis (red rectangle) of the image presented for the mCherry-αSyn transgenic larva in panel E. Scalebar 10 μm. (G) Image adapted from online Developmental Atlas, showing region of the section displayed in (Csingle bondF) (red arrow).
