HuVV and HuMV, transgenic mice expressing human PrP gene sequence coding for the valine-homozygous and methionine/valine-heterozygous codon 129 genotypes, respectively; NL-VV and UK-VV, patients from the Netherlands and United Kingdom, respectively, who had VPSPr and the valine-homozygous codon 129 genotype; PrP, prion protein; VPSPr, variably protease-sensitive prionopathy. Scale bars indicate 25 μm.
