摘要: Transmissible spongiform encephalopathies (TSEs), also known as prion diseases, including Creutzfeldt-Jakob disease (CJD) in human, Bovine Spongiform Encephalopathy (BSE) cow, and scrapie sheep, represent diseases with complex still poorly understood molecular mechanisms (Prusiner, 1998). The protein-only hypothesis postulates a possible pathogenic mechanism involving the protein. helix rich normal protein (PrPC) is found to be infected by its -sheet abnormal proteinase K (PK)-resistant form, PrPSc, converted into PrPSc This infection will lead aggregation of PrPSc-based amyloid fibrils that accumulate peripheral invade central nervous system damage neurons.
