| Cell Lines Or Primary Cells | |
| Animal Model | PDGF/α-syn transgenic mouse model of PD/DLB; non-transgenic mice also used for uptake controls |
| Administration Route | intraperitoneal injection, twice weekly for 4 weeks |
| Output Type | α-syn knockdown, neuronal protection, reduced neuroinflammation |
| Output Value | Reduced α-syn immunoreactivity by ~65–70% in neocortex, ~40–50% in hippocampus, and ~50–55% in striatum; ameliorated NeuN neuronal loss and TH fiber loss; reduced GFAP/Iba1 neuroinflammation |
| Output Units | |
| Output Notes | FITC-siα-syn delivered across BBB to neurons and astrocytes; co-localized with α-syn-accumulating neurons |
| Toxicity Notes | No observable CNS toxicity stated for siα-syn delivery; study noted no TH loss/inflammation from partial knockdown |
