Experimental details: Immunofluorescent analysis of alpha Synuclein in HeLa cells using an Alpha Synuclein recombinant rabbit monoclonal antibody (Product # 701085) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B) and actin stained with Alexa Fluor 594 phalloidin (red) (image C). Image D is a composite image showing cytoplasmic and nuclear localization of Alpha-Synuclein.

Experimental details: Immunofluorescent analysis of SNCA was performed on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0. 25% Triton X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with SNCA Recombinant Rabbit Monoclonal Antibody (Product # 701085) at a dilution of 1:1000 in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor® 488 Goat anti-Rabbit IgG secondary antibody (Product # A-11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 594 phalloidin (Product # A12381) and Panel d is a merged image showing nuclear localization and panel e is a control without primary antibody. The images were captured using a Nikon microscope at 20X magnification.

Experimental details: Flow cytometry analysis of SNCA was performed on HeLa cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0. 25% Tritonª X-100 for 20 minutes, and blocked with 5% BSA for 1 hour at room temperature. Cells were labeled with ABfinityª SNCA recombinant rabbit monoclonal antibody (Product # 701085, red histogram) or with rabbit isotype control (pink histogram) at a dilution of 1:400 in 2.5% BSA. After incubation at room temperature for 3 hours, the cells were labeled with Alexa Fluor¨ 488 goat anti-Rabbit Secondary antibody (Product # A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune¨ Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Experimental details: Figure 3 The PDE1 inhibitor vinpocetine reduces cell death and a 37 kDa alpha-Syn species. ( a ) Counts of vital, i.e. non-clumped, non-fragmented 4',6-diamidino-2-phenylindole (DAPI)-stained nuclei in untransduced control neurons (Ctrl, white bar), alpha-Syn transduced neurons (black bar) treated with solvent only, and alpha-Syn transduced neurons treated with different concentrations of vinpocetine (red bars) confirmed the compound's protective efficacy. ( b ) Confocal microscopy images of untransduced control neurons, alpha-Syn-transduced neurons treated with solvent, and alpha-Syn-transduced neurons treated with vinpocetine six days after transduction, stained with DAPI (blue), an alpha-Syn-antibody (green), and a beta-III-tubulin-antibody to demonstrate the axonal network (red). Scale bar: 20 um. ( c ) Quantification of the activated caspases signal after CellEvent TM staining in untransduced control neurons (left bar), alpha-Syn-transduced neurons treated with solvent (black bar), and alpha-Syn-transduced neurons treated with vinpocetine (red bar) showing activation of caspases 3 and 7 in alpha-Syn overexpressing neurons, which was reduced by treatment with 20 uM vinpocetine. ( d ) Representative images of the CellEvent TM staining. Scale bar 50 um. ( e ) Representative Western blot with an alpha-Syn antibody (C20, Santa Cruz) in lysates of control neurons and alpha-Syn-transduced neurons treated with solvent or with vinpocetine at different concentrations.

Experimental details: Figure 4 Mechanisms of action relevant for vinpocetine's efficacy. ( a - d ) LDH release was used to measure degeneration in untransduced control neurons (Ctrl, white bars), alpha-Syn-transduced neurons treated with solvent (black bars), and alpha-Syn-transduced neurons with different interventions (coloured bars). The sodium channel blocker tetrodotoxin ( a , green bars) and the L-type calcium channel blocker isradipine ( b , orange bars) in different concentrations did not protect against alpha-Syn-incuded toxicity. The adenylate cyclase stimulator forskolin ( c , FRK, blue bar) did also not protect, but the guanylate cyclase stimulator BAY41-2272 did ( c , yellow bar). ( d ) Western blot with an alpha-Syn antibody (C20, Santa Cruz) of untransduced control neurons (Ctrl), alpha-Syn-transduced neurons treated with solvent (second lane), and alpha-Syn-transduced neurons with forskolin (FRK) or BAY41-2272 showed that BAY41-2272 treatment also led to a reduction of a 37 kDa alpha-Syn band, while forskolin led to an increase of this band. ( e ) Quantification of the 37 kDa band. ( f ) A negative control siRNA (green bar) and siRNA against PDE1B (pink bar) did not protect, but siRNA against PDE1A (bright red bar) was strongly protective, and siRNA against PDE1C (dark red bar) was moderately protective. * P < 0.05, ** P < 0.01, *** P < 0.001, n.s. not significant, one-way ANOVA with Tukey's HSD post-hoc test.

Experimental details: Fig. 3. LUHMES cell clones differentiate into neurons and express dopaminergic markers. (A) Morphological analysis of naive and LRRK2-expressing LUHMES clones (L10WT and L14GS) was performed in live cells using the Incucyte S3 analysis system. Several parameters were analyzed with the Incucyte Neurotracker software using brightfield images. Nuclei were stained with the NucLight reagent (red). The displayed experiment is representative of two independent experiments. Scale bar: 25 um. (B) Differences in nuclear shape (eccentricity) were statistically significant between the G2019S clone L14GS and the naive LUHMES cells. WT LUHMES clone (L10WT) behaved similarly to the naive cells. Error bars show mean+-s.d. One-way ANOVA with Tukey's post-hoc test was performed. Differences with P =10 from two independent experiments. *** P
