WebAbstract. Prions, a self-templating amyloidogenic state of normal cellular proteins such as PrP, have been identified as the basis of a number of disease states, particularly diseases of the nervous system. This finding has led to the notion that protein aggregation, namely prionogenic aggregates and amyloids, is primarily harmful for the organism.
