This pretty big news. The first model of the infectious prion, which is a misfolded protein that causes disease in humans, sheep, and cows. It is particularly scary as a misfolded infectious protein can not be made inert with heat. Once injested it sets off a chain reaction causing the misfold to replicate and disrupt cellular functioning.

Protein folding is still a very mystery, simply from the number of combinations. Our computer processing power is still not robust enough to model it well.

Proteins can misfold and probably do regularly. it is not entirely understood. Recently it was demonstrated that a single copper ion can cause a misfold.

The body does have mechanism to find and degrade them so they don't build up in the body.

While mad cow disease is very scary, it appears that checks and regulation in the food supply where cow brain matter potentially enters the food supply works well. None the less. The infectious diesases are very scary.

Understanding protein folding and how misfolds happen is key to eliminating many non-infectious (thought to be noninfectious) protein misfold disease such as Alzheimers, Parkinson, ALS. Here is a list of disease where protein misfolding plays a significant part in the disease and/or disease progression.

That was a very good post. Thank you.

I would like to add that all prion diseases are untreatable and fatal.

I always been fascinated with prions, as far as "are they life", but I was not aware they affect us in so many ways.
The moment you declare a set of ideas to be immune from criticism, satire, derision, or contempt, freedom of thought becomes impossible. - Salman Rushdie

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts. - Bertrand Russell
