Mad cow disease prions capable of evolution, even without DNA

The Scripps Research Institute has published a study in the journal Science alleging that prions, lifeless protein particles that are believed to cause serious brain diseases, are able to mutate and develop resistance to drugs in the same way that bacteria and other living things do. Abnormal prion proteins cause at least 20 fatal diseases … Continue reading Mad cow disease prions capable of evolution, even without DNA

Mad Cow Disease in the USA: Understand Prions, Part II

Prions have been known by many scientists for many years. They are believed to cause disease by triggering an immune response when they enter an animal or human body. In 1997, Stanley Prusiner, MD, won the Nobel Prize for his discovery of prions, an acronym for proteinaceous infectious particles. Prions are associated with a variety … Continue reading Mad Cow Disease in the USA: Understand Prions, Part II

Mad cow disease research breakthrough: scientists recreate prions in the lab

Scientists in California have created the first synthetic version of prions. These are the so-called "rogue proteins" that are responsible for mad cow disease. To understand the significance of this research, it helps to fully understand what prions are in the first place and how they cause mad cow disease. Prions are abnormally folded proteins, … Continue reading Mad cow disease research breakthrough: scientists recreate prions in the lab

What is a Prion?

A prion protein is a naturally occurring protein that can be found throughout our bodies, and in high concentrations in the brain. In our live blood online course we are going step by step trough and explain how a healthy prion protein changes into an unhealthy prion, causing disease. A prion is a nonliving, self-replicating … Continue reading What is a Prion?
