Aberrant metal binding by prion protein in human prion disease.
Human prion diseases are characterized by the conversion of the normal prion protein (PrP(C)) into a pathogenic isomer (PrP(Sc)). Distinct PrP(Sc) conformers are associated with different subtypes of prion diseases. PrP(C) binds copper and has antioxidation activity. Changes in metal-ion occupancy can lead to significant decline of the antioxidation activity and changes in conformation of the p...
متن کاملFamilial Prion Disease Cases Without Mutation in PRNPGene
Phosphorus (P), in the form of phosphate ion (Pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. The objective of the present study was to assess the influence of fungal infection on Pi metabolism in compare to the effects of phosphate stress in Arabidopsis. Quantification of total P contents showe...
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 کاملRecombinant Human Prion Protein Inhibits Prion Propagation in vitro
Prion diseases are associated with the conformational conversion of the cellular prion protein (PrP(C)) into the pathological scrapie isoform (PrP(Sc)) in the brain. Both the in vivo and in vitro conversion of PrP(C) into PrP(Sc) is significantly inhibited by differences in amino acid sequence between the two molecules. Using protein misfolding cyclic amplification (PMCA), we now report that th...
متن کاملTotal prion protein levels in the cerebrospinal fluid are reduced in patients with various neurological disorders.
We performed a study on levels of the total prion protein (PrP) in humans affected by different neurological diseases and assessed the influence of several factors such as age, gender, and disease severity on the cerebrospinal fluid PrP levels. PrP-ELISA technique was used to analyze cerebrospinal fluid (CSF) samples. 293 CSF samples of patients with Creutzfeldt-Jakob-disease (CJD), Alzheimer's...
