Species barrier prevents an abnormal isoform of prion protein from accumulating in follicular dendritic cells of mice with Creutzfeldt-Jakob disease

Abstract

The accumulation of abnormal prion protein in follicular dendritic cells did not occur in mice inoculated with materials from human Creutzfeldt-Jakob disease, whereas it always occurred in mice inoculated with mouse-adapted agents, suggesting an intense expression of the species barrier in the lymphoreticular system.
