Abstract: | Prions are self-replicating protein aggregates and are the primary causative factor in a number of neurological diseases in mammals. The prion protein (PrP) undergoes a conformational transformation leading to aggregation into an infectious cellular pathogen. Prion-like protein spreading and transmission of aggregates between cells have also been demonstrated for other proteins associated with Alzheimer disease and Parkinson disease. This protein-only phenomenon may therefore have broader implications in neurodegenerative disorders. The minireviews in this thematic series highlight the recent advances in prion biology and the roles these unique proteins play in disease. |
