. LPS-stimulated J774 and BMDM cells, was quite unexpected, and gives rise to the hypothesis that these cells are able to transiently convert RML-PrP Sc . It is worth noting that J774 and primary BMDM cells. synthesis of PrP Sc . To verify this in activated phagocytic cells, we stimu- lated J774 and BV-2 cells with LPS and CpG-ODN for 4 h. As a control, cells were treated with nonstimu- lating G...
