Prion Protein Modulates Cellular Iron Uptake: A Novel Function with Implications for Prion Disease Pathogenesis


Converging evidence leaves little doubt that a change in the conformation of prion protein (PrP(C)) from a mainly alpha-helical to a beta-sheet rich PrP-scrapie (PrP(Sc)) form is the main event responsible for prion disease associated neurotoxicity. However, neither the mechanism of toxicity by PrP(Sc), nor the normal function of PrP(C) is entirely clear… (More)
