Prion diseases or transmissible spongiform encephalopathies (TSEs) are a family of rare progressive neurodegenerative disorders that affect both humans and animals. They are distinguished by long incubation periods, ... The causative agent of TSEs is believed to be a prion. A prion is an abnormal, transmissible agent that...

Prions are proteinaceous infectious particles that lack nucleic acids.(1) Prions are composed largely, if not entirely, of an abnormal isoform of a normal cellular protein.

The disturbing link between the prions that cause Bovine Spongiform Encephalopathy (BSE) in cattle and Creutzfeld-Jakob disease (CJD) in humans comes from a study of the evolutionary relationships of prions in a wide variety of mammals.

when prions are transmitted from one species to another disease develops only after a very long incubation period, if at all, but on serial passage in the new species the incubation time often decreases dramatically and then stabilises.

Prions is an acronym for proteinaceous infectious particles. They are the causative agents of a class of disease known as transmissible spongiform encephalopathies (TSE). Prions are a fascinating group of agents that challenge the conventional concepts of microbiology and even life.

In contrast to pathogens carrying a nucleic acid genome, prions appear to encipher strain-specific properties in the tertiary structure of PrPSc. Transgenetic studies argue that PrPSc acts as a template upon which PrPC is refolded into a nascent PrPSc molecule through a process facilitated by another protein.
