[From the Scrapie syndrome of sheep and goat to the mad cow disease - the history of the discovery of prion]

Abstract

Since the discovery of Scrapie Syndrome in sheep and goats in 1730, there emerged a series of diseases such as Creutzfeldt-Jakob disease, kuru disease and mad cow disease etc. In the research of kuru disease, the American scientist D. Carlteton Gajdusek found a new virus without the characteristic of DNA and RNA, which was awarded the Nobel Prize in physiology in 1976. Since then another American scientist, Stanley B. Prusiner, found a new virus-prion, taking protein as the genetic medium, which was awarded the Nobel prize in physiology and medicine in 1997. The discovery of prion is a great landmark in the research of life science, which laid a theoretical foundation for people to conquer a series of diseases such as Scrapie syndrome in sheep and goats, Creutzfeldt-Jakob disease, kuru disease and mad cow disease etc.
