Α-Synuclein in Parkinson's Disease. G 1006 buchman alpha synuclein. Α-Synuclein and neuronal cell death. Aspects of protein chemistry of α-synuclein and toxicity α-Synuclein has a strong tendency to self-associate in vitro [110, 111], and so a prime candidate for the underlying driving force for toxicity is the formation of aggregated species.
One of the important questions about this idea is which species are present in cells/tissues. Oligomeric species can be isolated from cells [112, 113, 114] and from human  and mouse (both wild type and α-synuclein transgenic) brain . In both cells and brain, oligomers are particularly found in membrane-enriched fractions [112, 115], suggesting a possible influence of the lipid environment on oligomer formation.
