Prion - Wikipedia
WEBA prion / ˈ p r iː ɒ n / ⓘ is a misfolded protein that can induce misfolding of normal variants of the same protein and trigger cellular death. Prions cause prion diseases known as transmissible spongiform encephalopathies (TSEs) that are fatal transmissible neurodegenerative diseases in humans and animals.
