Abstract

Prion is an infectious particle composed of an abnormal isoform of the prion protein (PrPSc) and causes prion diseases such as bovine spongiform encephalopathy (BSE), Creutzfeldt-Jakob disease (CJD) and scrapie. Host cells express cellular prion protein (PrPC), which plays roles in normal functions such as anti-oxidative stress. PrPSc is derived from PrPC and produced by conformational conversion. Prion is notorious as a resistant pathogen, being difficult to inactivate with conventional sterilization procedures. Therefore, to prevent prion-caused iatrogenic diseases, the use of appropriate procedures to inactivate prions is important. For examples, alcohol treatment, autoclave (121˚C, 20 min) and γ-ray irradiation, which are used for disinfection, antisepsis or sterilization of viruses and bacteria, are not effective against prion. This is a fundamental review of prions and methods of their inactivation.
