A pitfall in diagnosis of human prion diseases using detection of protease-resistant prion protein in urine. Contamination with bacterial outer membrane proteins.
Because a definite diagnosis of prion diseases relies on the detection of the abnormal isoform of prion protein (PrPSc), it has been urgently necessary to establish a non-invasive diagnostic test to detect PrPSc in human prion diseases. To evaluate diagnostic usefulness and reliability of the detection of protease-resistant prion protein in urine, we extensively analyzed proteinase K (PK)-resis...
متن کاملA Study on The Effect of Temperature on Human Prion Protein Structure through Molecular Dynamic Simulation
Background & Aims: The normal form of the prion protein is called PrPC and its infectious form is called PrPSc. This protein functions like a crystallized core for the transformation of PrPc into an abnormal PrPSc. The aim of the present study was to investigate the effect of temperature on human prion protein structure through molecular dynamic simulation. Methods: In this research, the GROMAC...
متن کاملEarly detection of chronic wasting disease prions in urine of pre-symptomatic deer by real-time quaking-induced conversion assay
Chronic wasting disease (CWD) is a prion disease of captive and free-ranging deer (Odocoileus spp), elk (Cervus elaphus nelsonii) and moose (Alces alces shirasi). Unlike in most other prion diseases, in CWD prions are shed in urine and feces, which most likely contributes to the horizontal transmission within and between cervid species. To date, CWD ante-mortem diagnosis is only possible by imm...
متن کاملMechanistic prospective for human PrPC conversion to PrPSc: Molecular dynamic insights
PrPC conversion to PrPSc isoform is the main known cause for prion diseases including Crutzfeldt-Jakob, Gerstmann-Sträussler-Sheinker syndrome and fatal familial insomnia in human. The precise mechanism underling this conversion is yet to be well understood. In the present work, using the coordinate file of PrPC (available on the Protein Data Bank) as a starting structure, separate molecular d...
متن کاملIntroducing critical residues in the human prion protein and its Asp 178 Asn mutant by molecular dynamics simulation
The molecular dynamics (MD) simulation method is used to assess structural details for humanprion protein (hereafter PrPN) and its Asp178 Asn mutant (hereafter PrPm) which causes fatalfamilial insomnia disease. The results reveal that the flexibility and instability increase in PrPmcould be related to specific amino acids exposed to the solvent. Solvation free energy of PrPm is 20kjmot1nni2 mor...
