WebPDF Prions are infectious proteins consisting mainly of PrP(Sc), a beta sheet-rich conformer of the normal host protein PrP(C), and occur in different strains. Strain identity is thought to be encoded by PrP(Sc) conformation. We found that biologically cloned prion populations gradually became heterogeneous by accumulating "mutants," and selective … WebPrions are an enigma amongst infectious disease agents as they lack a genome yet confer specific pathologies thought to be dictated mainly, if not solely, by the conformation of the disease form of the prion protein (PrPSc). Prion diseases affect humans and animals, the latter including the food-producing ruminant species cattle, sheep, goats and deer. …
