Generating recombinant C-terminal prion protein fragments of exact native sequence

Abstract

Transmissibility and distinctive neuropathology are hallmark features of prion diseases differentiating them from other neurodegenerative disorders, with pathogenesis and transmission appearing closely linked to misfolded conformers (PrPSc) of the ubiquitously expressed cellular form of the prion protein (PrPC). Given the apparent pathogenic primacy of misfolded PrP, the utilisation of peptides based on the prion protein has formed an integral approach for providing insights into misfolding pathways and pathogenic mechanisms. In parallel with studies employing prion peptides, similar approaches in other neurodegenerative disorders such as Alzheimer Disease, have demonstrated that differentia..
