Summary
Transmissible spongiform encephalopathies (TSEs), or prion diseases, are fatal neurodegenerative disorders caused by misfolded prion proteins (PrP). This review explores the structural basis of prion diseases and their unique transmissibility.
Area of Science:
- Neurodegenerative diseases
- Structural biology
- Mammalian prion biology
Background:
- Transmissible spongiform encephalopathies (TSEs), also known as prion diseases, are fatal neurodegenerative disorders affecting humans and mammals.
- These diseases stem from the misfolding and aggregation of the host prion protein (PrP).
- Prion diseases are unique due to their transmissibility and the existence of distinct strains associated with specific in vivo phenotypes.
Purpose of the Study:
- To review existing structural data for the prion protein (PrP).
- To correlate structural information with the known biology of prion diseases.
- To provide an overview of the molecular underpinnings of prion disease pathogenesis.
Main Methods:
- Literature review of biological and biophysical studies on PrP structure.
- Analysis of existing structural information for PrP.
- Integration of structural data with prion disease biology.
Main Results:
- Evidence suggests that protein conformation encodes the molecular basis of prion diseases.
- Structural insights into PrP aggregation are crucial for understanding disease mechanisms.
- Different PrP conformations may underlie prion disease strain diversity.
Conclusions:
- Prion disease pathogenesis is closely linked to the structural conformation of the prion protein (PrP).
- Understanding PrP structure is key to unraveling the mechanisms of TSEs.
- Further structural studies are essential for developing therapeutic strategies against prion diseases.

03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

01:25Protein Folding
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

03:00Molecular Chaperones and Protein Folding
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
