Prion proteins are involved in fatal neurodegenerative brain illnesses including Jacob-Creutzfeld Disease and “Mad Cow” disease. These diseases are like other neurodegenerative diseases in that the primary pathology starts with abnormal accumulation of proteins within brain cells. This project is a collaboration between two Hope Center faculty members: David Harris is an established prion neuroscientis; Heather True is a yeast cell biologist. Together, they have developed an innovative technique which uses yeast to screen many thousands of genes at a time, to find those genes which potentially inhibit protein misfolding and aggregation.
