So we see that usually the misfolding of a protein doesn't actually do much because our body is capable of denaturing and breaking down that misfolded protein or folding it correctly into that correct shape. But sometimes we get something called a Pryon, and these are very, very dangerous infectious agents. So up until recently, we thought that only bacterial cells and viruses are capable of infecting our bodies and the bodies of other animals. But now we know that these aggregate of misfolded proteins, those prions, can also act as infectious agents. They can easily be passed down from one individual to another and even from one organism to another. As we saw.
