Involvement of Cellular Prion Protein in α-Synuclein Transport in Neurons

Researchers of NANBIOSIS U7 Nanotechnology Unit are coauthors of the article “Involvement of Cellular Prion Protein in α-Synuclein Transport in Neurons” by Molecular Neurobiology

The cellular prion protein, encoded by the gene Prnp, has been reported to be a receptor of β-amyloid. Their interaction is mandatory for neurotoxic effects of β-amyloid oligomers. In this study, we aimed to explore whether the cellular prion protein participates in the spreading of α-synuclein. Results demonstrate that Prnp expression is not mandatory for α-synuclein spreading. However, although the pathological spreading of α-synuclein can take place in the absence of Prnp, α-synuclein expanded faster in PrPC-overexpressing mice. In addition, α-synuclein binds strongly on PrPC-expressing cells, suggesting a role in modulating the effect of α-synuclein fibrils.
