Disruption of both alleles of the prion protein gene, Prnp, renders mice resistant to prions; in a Prnp o/o line reported by some of us, mice progressively developed ataxia and Purkinje cell loss. Here we report torpedo-like axonal swellings associated with residual Purkinje cells in Prnp o/o mice, and we demonstrate abnormal myelination in the spinal cord(More)
To understand the posttranslational conversion of the cellular prion protein (PrPC) to its pathologic conformation, it is important to define the intracellular trafficking pathway of PrPC within the endomembrane system. We studied the localization and internalization of PrPC in CHO cells using cryoimmunogold electron microscopy. At steady state, PrPC was(More)
Polymorphic basic residues near the C terminus of the prion protein (PrP) in humans and sheep appear to protect against prion disease. In heterozygotes, inhibition of prion formation appears to be dominant negative and has been simulated in cultured cells persistently infected with scrapie prions. The results of nuclear magnetic resonance and mutagenesis(More)
