has not been established.
First described in 1936, Gerstmann-Straussler-Scheinkerr (GSS) syndrome is a familial human prion disease

Mallucci's team found that the buildup of mis-folded proteins in the brains of mice with prion disease
activated a natural defense mechanism in cells, which switches off the production of new proteins.
Of all the prion diseases

Shu Chen, associate director of the National Prion Disease
Pathology Surveillance Center at Case Western Reserve University in Cleveland, Ohio, explains why: "The current understanding is the prion is an infectious agent made up of an abnormal form of protein.
