Predicting TSE transmission
Published 2008Table of Contents: “…Contents: The TSEs continue to pose a problem to animal and human health -- The vCJD epidemic appears to be in decline but new risks of human to human transmission are now apparent -- Chronic wasting disease is a major problem currently in the US although its presence has not yet been detected in Europe -- Predicting and preventing transmission of disease requires an understanding of the routes of transmission within and between animals and the host factors which determine susceptibility -- We have studied natural disease and both in vivo and in vitro model systems to unravel the basic mechanisms of disease -- PrP protein has a central role in the outcome disease and mutations and polymorphisms in host PrP can profoundly alter the host's susceptibility to a TSE agent -- Precisely how host PrP influences the outcome of disease has not been established -- Both mutations and glycosylation can profoundly influence transmission both within and between species.…”

Transgenic mouse models of prion diseases
Published 2008Table of Contents: “…Contents: Prions represent a new biological paradigm of protein-mediated information transfer -- Prions are the cause of fatal, transmissible neurodegenerative diseases, often referred to as transmissible spongiform encephalopathies (TSEs) -- Many unresolved issues remain including the exact molecular nature of the prion, the detailed mechanism of prion propagation, and the mechanism by which prion diseases can be both genetic and infectious -- The factors governing the transmission of prions between species remain unclear, in particular the means by which prion strains and PrP primary structure interact to affect inter-species prion transmission -- Dramatic advances in our understanding of prions have occurred because of their transmissibility to experimental animals and the development of transgenic (Tg) mouse models has done much to further our understanding about various aspects of prion biology.…”
