abstract：:The conversion of cellular prion protein (PrP(C)) to its protease-resistant isoform is involved in the pathogenesis of prion disease. Although PrP(C) is a ubiquitous glycoprotein that is present in various cell types, the physiological role of PrP(C) remains obscure. The present study aimed to determine whether PrP(C)...
