alpha-Synuclein (αS) is a presynaptic protein implicated in Parkinson’s disease (PD). Growing evidence implicates mitochondrial dysfunction, oxidative stress and αS-lipids interactions in the gradual accumulation of αS in pathogenic forms and its deposition in Lewy bodies, the pathological hallmark of PD and related synucleinopathies. The peroxisomal biogenesis disorders (PBD), with Zellweger syndrome serving as the prototype of this group, are characterized by malformed and functionally impaired peroxisomes. Here we utilized the PBD mouse models, Pex2-/-, Pex5-/- and Pex13-/-, to study the potential effects of peroxisomal dysfunction on αS–related pathogenesis. We found increased αS oligomerization and phosphorylation and its increased deposition in cytoplasmic inclusions in these PBD mouse models. Further, we show that αS abnormalities correlate with the altered lipid metabolism and specifically, with accumulation of long chain, n-6 polyunsaturated fatty acids, that occurs in the PBD models.
