A few experimental pieces of evidence show that the prions are not ordinary infectious materials. It is believed to be a “self-replicating protein”. Types of Prion Diseases Prion diseases can be of three types- acquired, sporadic, or genetic. Proteins showing prion-type behavior are also found in some fungi, which has been useful in helping to understand mammalian prions. Fungal prions do not appear to cause disease in their hosts. In yeast, protein refolding to the prion configuration is assisted by chaperone proteins such as Hsp104. All known prions induce the formation of an amyloid fold, in which the protein polymerises into an aggregate consisting of tightly packed beta sheets.
