Abstract
Cell based models used for the study of prion diseases have traditionally employed mouse-adapted strains of sheep scrapie prions. To date, attempts to generate human prion propagation in cell culture have been unsuccessful. Rabbit kidney epithelial cells (RK13) are permissive to infection with prions from a variety of species upon expression of cognate PrP transgenes. We explored RK13 cells expressing human PrP for their utility as a cell line capable of sustaining infection with human prions. RK13 cells processed exogenously expressed human PrP similarly to exogenously expressed mouse PrP but were not permissive to infection when exposed to sporadic Creutzfeldt-Jakob disease prions. Transmi..
