siRNA therapeutic applications in Parkinson’s disease.

Target gene Delivery system Model(s) Effect(s) Reference

α-synuclein
(SNCA)
Anionic liposomes decorated with a rabies virus glycoprotein
-derived peptide
In vitro:
neuronal cell from P0 newborn C57BL/6J mice
-Reducing the level of SNCA [77]
Naked siRNA In vitro:

(BE(2)-M17)
In vivo:
wild-type C57BL6
female mice
-Reducing the level of SNCA [90]*
Naked siRNA In vivo:
Primate Substantia Nigra
Reducing the level of SNCA and the first evidence of
successful anti-α-syn uclein intervention in the primate
[91]*
Viral vector
(AAV vectors))
In vivo:
Thy1-hSNCA mice
-Decreased hSNCA expression
-Rescue of hSNCA-mediated behavioral deficits
[92]*
ExCont-RNAi In vitro:

[93]*
Nanoparticle (LDH) In vitro:
human neuroblastoma cell line
(SH-SY5Y)
-Reducing the level of SNCA [165]
PEG-PEI In vitro:
PC12 cells
-Protect cells from death via apoptosis [166]
PEI F25- LMW In vitro:
