Abstract This review summarises the current field of prions including our understanding of the underlying mechanisms involved in the development of neurodegenerative disorders alongside current treatments. Transmissible spongiform encephlopathies (TSEs), also known as prion diseases, describe a group of these neurodegenerative disorders affecting animals and humans. Formation of protein amyloid aggregates leading to accumulation of misfolded protein is thought to be the event greatly responsible for the manifestation of these disorders. Computational models have assisted in the understanding of protein folding by recreating protein folding events that have allowed the mechanism of aggregation of protein into fibrillar species to surface. This article describes the pathways involved in protein folding, aggregation and self-assembly of proteins including the consequences involved when aberrant folding occurs. Therapeutic strategies in treating patients with prion disease are also discussed.
