Prion proteins can adopt self-propagating alternative conformations that account for the infectious nature of transmissible spongiform encephalopathies (TSEs) and the epigenetic inheritance of certain traits in yeast. Recent evidence suggests a similar propagation of misfolded proteins in the spreading of pathology of neurodegenerative diseases including(More)
To test if Caenorhabditis elegans could be established as a model organism for prion study, we created transgenic C. elegans expressing the cytosolic form of the mouse prion protein, MoPrP(23-231), which lacks the N-terminal signal sequence and the C-terminal glycosylphosphatidylinisotol (GPI) anchor site. We report here that transgenic worms expressing(More)
The infectious agent of prion diseases is believed to be nucleic acid-free particles composed of misfolded conformational isomers of a host protein known as prion protein (PrP). Although this "protein-only" concept is generally accepted, decades of extensive research have not been able to elucidate the mechanisms by which PrP misfolding leads to(More)
