Figure 5. Immunohistochemical analyses of disease-associated prion protein (PrP) in the CNS of transgenic (Tg) and gene-targeted (Gt) mice infected with Finland, Norwway, and North America chronic wasting disease (CWD) isolates. A) GtQ mice (CWD-susceptible Gt mice in which the PrP coding sequence was replaced with one encoding glutamine at codon 226) infected with CWD isolate from Finland moose 1 (MF-1). B) TgE mice (Tg mice expressing cervid PrP with glutamate at residue 226) infected with M-F1. C) GtQ mice infected with CWD isolate from Norway moose 1 (M-NO1). D) GtQ mice infected with CWD isolate from US moose 1. Arrows in panels A, B, and C indicate small puncta of PrP. Immunohistochemistry sections were stained with fragment antigen binding D18.
