A number of studies have suggested that macrophages, dendritic cells, and follicular dendritic cells play an important role in the propagation of PrPSc. Both accumulation and proteolysis of PrPSchave been demonstrated in peripheral macrophages. Macrophages may act as reservoirs for PrPScparticles if the cells die during transient PrPScpropagation. However, whether cell death plays a role in PrPScpropagation in macrophages remains unclear. In this study, we investigated the possibility of propagation and transmission of PrPScbetween dead immune cells and living neural cells. We found that under specific conditions, transient PrPScpropagation occurs in dead cells, indicating that interaction between PrPCand PrPScon plasma membrane lipid rafts might be important for PrPScpropagation. Co-culturing of killed donor PrPSc-infected macrophages with recipient N2a-3 neuroblastoma cells accelerated PrPSctransmission. Our results suggest that cell death may play an important role in PrPScpropagation, whereas transient PrPScpropagation in macrophages has little effect on PrPSctransmission.
