CNS pathogenesis of prion diseases.
Prion diseases or transmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative diseases, clinically characterised by cognitive decline, paralleled by severe damage to the central nervous system. Prion diseases have attracted a broad interest because of their unique mechanisms of replication and propagation; however, the underlying pathogenic mechanisms are still highly speculati...
متن کاملMolecular Pathogenesis of Prion Diseases
In humans, prion diseases occur with unique aetiology as sporadic, genetic or infectious disorders. Sporadic cases of prion diseases, which account for the majority of casualties (up to 85% of all cases), are of unknown origin; the genetic forms are less frequent (up to 15%), while the infectious cases are extremely rare with an incidence of less than 1% (Prusiner, 2001). Creutzfeldt-Jakob dise...
متن کاملCellular pathogenesis in prion diseases.
Prion diseases are characterised by neuronal loss, vacuolation (spongiosis), reactive astrocytosis, microgliosis and in most cases by the accumulation in the central nervous system of the abnormal prion protein, named PrP(Sc). In this review on the "cellular pathogenesis in prion diseases", we have chosen to highlight the main mechanisms underlying the impact of PrP(C)/PrP(Sc) on neurons: the n...
متن کاملThe peripheral nervous system and the pathogenesis of prion diseases.
Prion diseases are inevitably fatal neurodegenerative conditions which affect humans and a wide variety of animals. Unlike other protein aggregation diseases such as Alzheimer's, Parkinson's, and polyglutamine repeat diseases, prion diseases are unique in that they are transmissible. Therefore, prion diseases are also called transmissible spongiform encephalopathies. A number of prion diseases ...
متن کاملMolecular pathogenesis of sporadic prion diseases in man
The yeast, fungal and mammalian prions determine heritable and infectious traits that are encoded in alternative conformations of proteins. They cause lethal sporadic, familial and infectious neurodegenerative conditions in man, including Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker syndrome (GSS), kuru, sporadic fatal insomnia (SFI) and likely variable protease-sensitive pri...
