In this study, we tested the hypothesis that the glycosylation of the pathogenic isoform of the prion protein (PrP(Sc)) might encode the selective neurotropism of prion strains. We prepared unglycosylated cellular prion protein (PrP(C)) substrate molecules from normal mouse brain by treatment with PNGase F and used reconstituted serial protein cyclic misfolding amplification reactions to produce RML and 301C mouse prions containing unglycosylated PrP(Sc) molecules. Both RML- and 301C-derived prions containing unglycosylated PrP(Sc) molecules were infectious to wild-type mice, and neuropathological analysis showed that mice inoculated with these samples maintained strain-specific patterns of PrP(Sc) deposition and neuronal vacuolation. These results show that PrP(Sc) glycosylation is not necessary for strain-dependent prion neurotropism.
