Prions are not living organisms. Prions are infectious proteins. For unknown reasons, these proteins refold abnormally and cause a domino effect in surrounding proteins which in turn mutate into stable structures. Prions will then cause tissue damage and cell death to surrounding areas
If prion proteins refold, they can change into abnormally structured, infectious prion proteins.
Im scared im going to become a zombie, how does it spread?
When prions become misfolded, they turn into contagious pathogens that recruit any other prions they come into contact with, grouping together in clumps that damage other cells and eventually cause the brain itself to break down.
