Development of A High-Throughput System For Screening of Anti-Prion Molecules
<p>The misfolded prion protein causes and transmits disease in both humans and animals. As other infectious agents, prions display strain variation, which can generate different pathological outcomes in affected individuals. Unfortunately, there are no known therapies for these diseases, which at …

Yeast Prion Variants as Models of the Phenotypic and Pathological Consequences of Amyloid Polymorphism
… disorders such as Alzheimer's disease and prion diseases. Prions are infectious proteins that propagate a self- templating amyloid structure, and have become a model for studying these diseases. Interestingly, a single protein can form a variety of distinct amyloid structures, a phenomenon …

Prions Propagate as Dynamic Strain Mixtures
Prions are the agent responsible for a group of transmissible and inevitably fatal neurodegenerative disease in humans and other mammals. Prion disease is caused by the misfolding of a host encoded protein, PrPC, into the infectious conformation PrPSc. Phenotypic differences in disease (i.e., …

Mechanism of yeast prion portein aggregation and strain formation
Misfolding and aggregation of the prion protein: PrP) causes fatal neurodegenerative diseases in many mammalian species, including humans. Mutations in the gene encoding PrP are associated with ~15% of the incidences, while, the vast majority of the cases are sporadic. Interestingly, prion diseases …

Cross-Seeding Potential of Misfolded Amyloid-Beta Strains On Tau Protein: Examining The Puzzle Pieces of Alzheimer'S Disease
… features similar to those seen in infectious prions, such as their conformational strain diversity. Prion strains trigger diseases that may substantially vary in their pathological and clinical aspects. One example of strain diversity in Aβ can be found in the synthetic 2F and 3F fibrils. …

Mechanisms of Prion Strain Interference
Prion diseases are infectious neurodegenerative disorders that affect humans and other mammals and are inevitably fatal. The infectious agent in prion disease (PrPSc) is an abnormal isoform of an endogenous host protein (PrPC). Prion conversion involves a conformational change of PrPC into PrPSc, …

Deciphering the Molecular Basis of the Species Barrier in Prion Disease Using Bank Vole PrP
Prion disease is an infectious and fatal neurodegeneration condition which depends on the structural reconfiguration of a predominantly α-helical cellular protein called PrPC into a β-sheet rich conformer referred to as scrapie or PrPSc. The infectious nature of this conformer enables it to …
