In this chapter

In 1982, Stanley Prusiner at the University of California, San Francisco isolated the infectious agent behind spongiform encephalopathies and showed it was neither a bacterium nor a virus. He demonstrated it was simply a misfolded protein with no genetic material, capable of causing disease on its own.

  1. 01

    Prusiner coined the term prion for this new class of infectious agent.

  2. 02

    Mad cow disease is cited as an example of a prion disease.

  3. 03

    Prusiner won the 1997 Nobel Prize in Medicine for this work.

1:10:25>> Moving on to 1982, the discovery of pions. >> Yes. Um this was Stanley Prusener at University of California, San Francisco. He isolated an infectious agent behind the spongifform encphilopathies. And he showed that that pathogen is not a bacteria. It's not a virus. It's not even anything that is living. It is simply a misfolded protein with no genetic material. But it's wreaking havoc. Mhm. >> This is huge, right? Because before like for for like so much of humanity, we've been worried about viruses and bacteria

1:11:05and like sometimes um protests or like you know like little single-sellled organisms, the stuff that malaria comes from and now we've got something that's not even living and it's giving us a lot of grief. Yes. Um he coined the term pryion. I think mad cow disease is another um example of pryion disease. He won the 1997 Nobel Prize in Medicine. >> Yeah, that's a big one. >> It's a big one because it's it expands all of the things that we need to be worried about. >> Right. Right. >> There's new enemies we need to be aware of here. >> Uh 1982 discovery of uh ribosomes.
