Prion disease: All you need to know - Medical News Today

A prion /ˈpriːɒn/ (listen) is a misfolded protein that can transmit its misfolded shape onto normal variants of the same protein. Prions are the causative agent of several transmissible and fatal neurodegenerative diseases in humans and other animals. It remains unknown what causes a normal protein to misfold into a … See more The word prion, coined in 1982 by Stanley B. Prusiner, is derived from protein and infection, hence prion, and is short for "proteinaceous infectious particle", in reference to its ability to self-propagate and transmit its … See more Structure The protein that prions are made of (PrP) is found throughout the body, even in healthy people and animals.

Some of these proteins have been implicated in the ontogeny of age-related neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration with ubiquitin-positive inclusions See more The first hypothesis that tried to explain how prions replicate in a protein-only manner was the heterodimer model. This model assumed that a single PrP molecule binds to a single PrP molecule and catalyzes its conversion into PrP . The two PrP molecules then … See more Proteins showing prion-type behavior are also found in some fungi, which has been useful in helping to understand mammalian prions.
