Carina Henrikssonh PrP., a modified form of PrP.. PrP. is a normal host protein encoded by a single copy gene (.) and is found predominantly on the surface of neurons. PrP., in contrast to PrP., is resistant to protease and accumulates intracellularly. Prusiner proposed that PrP., when introduced into a nominal host
