The prion diseases illustrate three manifestations of CNS degeneration: (1) infectious (2) sporadic and (3) dominantly inherited forms. TME, CWD, BSE, FSE, EUE are all thought to occur after consumption of prion-infected foodstuffs.<ref>PMID:19936054</ref> <ref>PMID:1671440</ref> <ref>PMID:1975028</ref> <ref>PMID:8461023</ref> <ref>PMID:7902693</ref> <ref>PMID:7906019</ref> <ref>PMID:7913755</ref> <ref>PMID:8909447</ref> <ref>PMID:9266722</ref> <ref>PMID:10790216</ref> Defects in PRNP are the cause of Creutzfeldt-Jakob disease (CJD) [MIM:[http://omim.org/entry/123400 123400]]. CJD occurs primarily as a sporadic disorder (1 per million), while 10-15% are familial. Accidental transmission of CJD to humans appears to be iatrogenic (contaminated human growth hormone (HGH), corneal transplantation, electroencephalographic electrode implantation, etc.). Epidemiologic studies have failed to implicate the ingestion of infected annimal meat in the pathogenesis of CJD in human. The triad of microscopic features that characterize the prion diseases consists of (1) spongiform degeneration of neurons, (2) severe astrocytic gliosis that often appears to be out of proportion to the degree of nerve cell loss, and (3) amyloid plaque formation. CJD is characterized by progressive dementia and myoclonic seizures, affecting adults in mid-life. Some patients present sleep disorders, abnormalities of high cortical function, cerebellar and corticospinal disturbances. The disease ends in death after a 3-12 months illness.<ref>PMID:19936054</ref> <ref>PMID:1671440</ref> <ref>PMID:1975028</ref> <ref>PMID:8461023</ref> <ref>PMID:7902693</ref> <ref>PMID:7906019</ref> <ref>PMID:7913755</ref> <ref>PMID:8909447</ref> <ref>PMID:9266722</ref> <ref>PMID:10790216</ref> Defects in PRNP are the cause of fatal familial insomnia (FFI) [MIM:[http://omim.org/entry/600072 600072]].

The dementia was characterized clinically by frontotemporal features, including early personality changes.

May play a role in iron uptake and iron homeostasis. Soluble oligomers are toxic to cultured neuroblastoma cells and induce apoptosis (in vitro). Association with GPC1 (via its heparan sulfate chains) targets PRNP to lipid rafts.

+ | Prion infection is characterized by the conversion of host cellular prion protein (PrP(C)) into disease-related conformers (PrP(Sc)) and can be arrested in vivo by passive immunization with anti-PrP monoclonal antibodies. Here, we show that the ability of an antibody to cure prion-infected cells correlates with its binding affinity for PrP(C) rather than PrP(Sc). We have visualized this interaction at the molecular level by determining the crystal structure of human PrP bound to the Fab fragment of monoclonal antibody ICSM 18, which has the highest affinity for PrP(C) and the highest therapeutic potency in vitro and in vivo. In this crystal structure, human PrP is observed in its native PrP(C) conformation. Interactions between neighboring PrP molecules in the crystal structure are mediated by close homotypic contacts between residues at position 129 that lead to the formation of a 4-strand intermolecular beta-sheet. The importance of this residue in mediating protein-protein contact could explain the genetic susceptibility and prion strain selection determined by polymorphic residue 129 in human prion disease, one of the strongest common susceptibility polymorphisms known in any human disease. | ||
