OBJECTIVE To establish with improved accuracy the prevalence of disease related prion protein (PrP(CJD)) in the population of Britain and thereby guide a proportionate public health response to limit the threat of healthcare associated transmission of variant Creutzfeldt-Jakob disease (vCJD). DESIGN Cross sectional opportunistic survey. Study samples(More)
Prion diseases are a group of invariably fatal neurodegenerative disorders that include Creutzfeldt-Jakob disease in humans, scrapie in sheep and goats, and bovine spongiform encephalopathy in cattle. The infectious agent or prion is largely composed of an abnormal isoform (PrPSc) of a host encoded normal cellular protein (PrPc). The conversion of PrPc to(More)
Prion diseases are associated with accumulation of strain-dependent biochemically distinct, disease-related isoforms (PrP(Sc)) of host-encoded prion protein (PrP(C)). PrP(Sc) is characterised by increased beta-sheet content, detergent insolubility and protease resistance. Recombinant alpha-PrP adopts a PrP(C)-like conformation, while beta-PrP(More)
Protective monoclonal antibodies (MAbs) to the major outer membrane protein (MOMP) of species of the family Chlamydiaceae, which is the primary vaccine candidate antigen, recognize nonlinear epitopes conferred by the oligomeric conformation of the molecule. Protective MAbs failed to recognize oligomeric MOMP of the variant strain LLG, which bears amino acid(More)
Conversion of the cellular alpha-helical prion protein (PrP(C)) into a disease-associated isoform (PrP(Sc)) is central to the pathogenesis of prion diseases. Molecules targeting either normal or disease-associated isoforms may be of therapeutic interest, and the antibodies binding PrP(C) have been shown to inhibit prion accumulation in vitro. Here we(More)
