Immunohistochemical examination demonstrated widespread granular deposits of alpha-synuclein (alphaSN) in the brains of sheep and goats with natural scrapie, especially in the cornu ammonis and subiculum of the hippocampus; this contrasted with the diffuse and non-granular immunolabelling seen in healthy controls. There was non-regular "co-localization" of PrP(Sc) and alphaSN. The findings resembled those reported in Creutzfeldt-Jakob disease and in experimental prion disease in hamsters and mice. The results suggest that perturbation of alphaSN metabolism plays a role in human and animal prion diseases.

UI MeSH Term Description Entries
D011328 Prions Small proteinaceous infectious particles which resist inactivation by procedures that modify NUCLEIC ACIDS and contain an abnormal isoform of a cellular protein which is a major and necessary component. The abnormal (scrapie) isoform is PrPSc (PRPSC PROTEINS) and the cellular isoform PrPC (PRPC PROTEINS). The primary amino acid sequence of the two isoforms is identical. Human diseases caused by prions include CREUTZFELDT-JAKOB SYNDROME; GERSTMANN-STRAUSSLER SYNDROME; and INSOMNIA, FATAL FAMILIAL. Mink Encephalopathy Virus,Prion,Encephalopathy Virus, Mink
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
