A prion (n) in the Scrapie form (PrPSc) is an infectious agent composed of protein in a misfolded form. This is the central idea of the Prion Hypothesis, which remains debated. This would be in contrast to all other known infectious agents, like viruses, bacteria, fungi or parasites—which must contain nucleic acids (either DNA, RNA, or both). Th...

The word, for proteinaceous infectious agent, was coined in 1982 by neurologist Stanley Prusiner as part of a hypothesis regarding ailments bearing aetiologic resemblance to those caused by slow viruses (for instance, kuru). The hypothesis has been borne out by investigation. Prions are now believed responsible for several transmissible neurodegene...

(pri´on) (pre´on) any of several pathogenic, transmissible forms of the core of prion protein that cause a group of degenerative diseases of the nervous system known as prion diseases.

A disease-causing agent that is neither bacterial nor fungal nor viral and contains no genetic material. A prion is a protein that occurs normally in a harmless form. By folding into an aberrant shape, the normal prion turns into a rogue agent. It then coopts other normal prions to become rogue prions.
