Visualization of early oligomeric α-synuclein pathology and its impact on the dopaminergic system in the (Thy-1)-h[A30P]α-syn transgenic mouse model.

J Neurosci Res 2021 Jul 22. Epub 2021 Jul 22.

Department of Public Health and Caring Sciences, Uppsala University, Uppsala, Sweden.

Aggregation of alpha-synuclein (α-syn) into Lewy bodies and Lewy neurites is a pathological hallmark in the Parkinson´s disease (PD) brain. The formation of α-syn oligomers is believed to be an early pathogenic event and the A30P mutation in the gene encoding α-syn, causing familial PD, has been shown to cause an accelerated oligomerization. Due to the problem of preserving antigen conformation on tissue surfaces, α-syn oligomers are difficult to detect ex vivo using conventional immunohistochemistry with oligomer-selective antibodies.
