Prion


The term "prions" refers to abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins called prion proteins that are found most abundantly in the brain. The functions of these normal prion proteins are still not completely understood.

A prion disease is a type of proteopathy, or disease of structurally abnormal proteins. In humans, prions are believed to be the cause of Creutzfeldt-Jakob disease (CJD), its variant (vCJD), Gerstmann-Sträussler-Scheinker syndrome (GSS), fatal familial insomnia (FFI), and kuru.

A prion is a type of protein that can trigger normal proteins in the brain to fold abnormally. Prion diseases can affect both humans and animals and are sometimes spread to humans by infected meat products. The most common form of prion disease that affects humans is Creutzfeldt-Jakob disease (CJD). Prion diseases are rare.

Prion diseases, also known as transmissible spongiform encephalopathies or TSEs, are a group of rare, fatal brain diseases that affect animals and humans. They are caused by an infectious agent known as a prion, which is derived from a misfolded version of a normal host protein known as prion protein.

"'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.

Classic CJD is a human prion disease. It is a neurodegenerative disorder with characteristic clinical and diagnostic features. This disease is rapidly progressive and always fatal. Infection with this disease leads to death usually within 1 year of onset of illness.

To others, a prion is what forms long-term memories. To others still, a prion is what causes anti-fungal resistance and allows life forms to evolve in new environments. This wide range of variation in how we define what a prion is vs. what a prion does not leads to unproductive conversations among professionals working in relevant fields of study.

Collapse Section Prion disease represents a group of conditions that affect the nervous system in humans and animals.

A prion is a type of protein that can cause disease in animals and humans by triggering normally healthy proteins in the brain to fold abnormally. The prion mode of action is very different to bacteria and viruses as they are simply proteins, devoid of any genetic material.

The prion protein (PrP) undergoes a conformational transformation leading to aggregation into an infectious cellular pathogen. Prion-like protein spreading and transmission of aggregates between cells have also been demonstrated for other proteins associated with Alzheimer disease and Parkinson disease.

Prions are infectious agents that long defied some of our basic ideas of biology. They appear to behave like other infectious organisms, yet they lack any of the most fundamental features of organisms. In particular, they lack any genetic material (DNA or RNA).

Prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative diseases by an entirely novel mechanism. Prion diseases may present as genetic, infectious, or sporadic disorders, all of which involve modification of the prion protein (PrP). Bovine spongiform en …

Prion diseases (collectively known as transmissible spongiform encephalopathies) comprise multiple conditions that can affect both humans and other animals. The most commonly known prion disease that affects humans is Creutzfeldt-Jakob Disease (CJD) and its variations.

In animals, prion diseases include scrapie in sheep and bovine spongiform encephalopathy, commonly known as mad cow disease in cattle. In humans, diseases such as kuru and Creutzfeldt-Jakob disease (CJD) are also thought to be caused by prions.
