How are prions related to viruses?

How are prions related to viruses?

Infections: Prions and viruses can be transmitted from person to person, animal to animal. That is the only characteristic that is in common between viruses and prions. Viruses have typical genetic material, either dna or rna, and work with the host cell's own genetic machinery. Prions are abnormal proteins that encourage abnormal folding of proteins in the host. ...Read more

How common are prion diseases?

How common are prion diseases?

Not very: Hi, the most common prion disease is CJD, with a uniform incidence of approximately 1 case per million population both in the United States and internationally. Familial forms of prion diseases, such as GSS and fatal familial insomnia (FFI), are much more rare. About 10% of cases of CJD are familial, with an autosomal dominant pattern of inheritance linked to mutations in the PRNP gene. ...Read more

How do prions multiply without nucleic acids?

Structure change: Prions are abnormally folded versions of normal proteins. When a prion comes into contact with the "normal" version of itself, it changes the normal protein's structure into a prion. ...Read more

Not clear: Prions are duplications of Amino Acid chains that populate the brain and crowd out the normal brain components, causing gradual dementia and motor changes and eventually death. There is no known cure. ...Read more

How do prions enter the body?

How do prions enter the body?

By mouth: These abnormal proteins which can lead to brain degeneration are in food containing brain tissue from affected animals. Herds are checked for this so this incidence is very rare. Cooking does not destroy them. There are probably 1-3 cases of this in the us per year. ...Read more

Can you get prions from cold hot dogs ?

Can you get prions from cold hot dogs ?

Not temp: It's a good question. Many bacterially affected food can be made safe by high temperature. Not so for prion infected meat. This means that whether cold or hot, badly prion infected meat cannot be made safe by heating. The good news is that prion-dangerous beef is exceedingly rare, whether processed or butchered. ...Read more

Are prions implicated in any human illness?

Yes: Traditionally classified human prion diseases include creuztfeld-jakob diseases (cjd), gerstmann-straussler-scheinker (gss) disease, fatal familial insomnia and kuru. Certain animal prion disease can be transmitted to humans including bovine spongifrm encephalopathy (mad cow disease), chronic wasting disease of mule deer and elk, and scrapie in sheep and goats. ...Read more

How many known "species" of prions are there?

How many known "species" of prions are there?

Tough question: There are about two dozen known prion diseases caused by more or less distinct prions. Yet the underlying prions do fal, into two large classes. Then there are normal prion type proteins found throughout the body and in the brain. The truth is that this is afield of such new and active research that a solid taxonomy has not yet been developed (so far as i know). ...Read more

What is necessary for the replication of a prion?

The abnormal protein: Doesn't replicate per se, it produces more of itself by changing the conformation (folding) of the normal cellular protein. These misfolded proteins then begin to agglutinated into plaques which can damage the nerve cell. ...Read more
