Studies on Prion Replication in Spleen
Some of the early events following scrapie infection take place in the lymphoreticular system (LRS) and result in significant replication of prions in lymphoid organs. The identity of the cells in the LRS that produce prions and their role in neuroinvasion are still unknown. We find that in the spleen of scrapie-infected mice, prions are associated with T and B cells and to a somewhat lesser de...
متن کاملFollicular Dendritic Cell-Specific Prion Protein (PrPc) Expression Alone Is Sufficient to Sustain Prion Infection in the Spleen
Prion diseases are characterised by the accumulation of PrP(Sc), an abnormally folded isoform of the cellular prion protein (PrP(C)), in affected tissues. Following peripheral exposure high levels of prion-specific PrP(Sc) accumulate first upon follicular dendritic cells (FDC) in lymphoid tissues before spreading to the CNS. Expression of PrP(C) is mandatory for cells to sustain prion infection...
متن کاملPrion disease induced alterations in gene expression in spleen and brain prior to clinical symptoms
Prion diseases are fatal neurodegenerative disorders that affect animals and humans. There is a need to gain understanding of prion disease pathogenesis and to develop diagnostic assays to detect prion diseases prior to the onset of clinical symptoms. The goal of this study was to identify genes that show altered expression early in the disease process in the spleen and brain of prion disease-i...
متن کاملStrain-specific spleen remodelling in Plasmodium yoelii infections in Balb/c mice facilitates adherence and spleen macrophage-clearance escape
Knowledge of the dynamic features of the processes driven by malaria parasites in the spleen is lacking. To gain insight into the function and structure of the spleen in malaria, we have implemented intravital microscopy and magnetic resonance imaging of the mouse spleen in experimental infections with non-lethal (17X) and lethal (17XL) Plasmodium yoelii strains. Noticeably, there was higher pa...
متن کاملFrom the Escape Property to Escape Analysis
operations for its analysis. We show that the analysis induced by E is very imprecise. Hence, in Section 5 we refine the domain E into the more precise domain ER for escape analysis. In Section 6, we discuss our prototype implementation and experimental results. Section 7 concludes the paper by highlighting the differences between previous proposals and our own approach. Section 8 contains the ...
