However, our knowledge of prions in higher organisms is limited to a handful of examples associated to serious illnesses, thereby the need for strategies that can point out new putative candidates that might be coupled to other cellular functions.
Detailed knowledge of the mechanisms controlling prion colonization of muscle may help to explain the role of muscle in neuroinvasion of prions from the periphery to the brain [ 43, 44].
This is, to our knowledge, the first formal demonstration of prion propagation in a non-eukaryote.
Prions: The New Biology of Proteins describes the current state of knowledge about the enigmatic world of prion diseases.
This article provides a review of the current state of genetic knowledge regarding prion diseases in cattle.
However, as present knowledge of structure-function correlations in prion proteins consists primarily of the observation, that the same polypeptide chain can be found either in PrPC or PrPSc, and neither typical protein functions nor possible functional sites have been unambiguosly identified for PrPC, searches for physiologically relevant structural features have so far been highly speculative.
Moreover, the reported association analysis contributes to the knowledge of the molecular mechanisms underlying the pathogenesis of prion diseases.
This book will be valuable to prion disease researchers, to scientists who want to gain more knowledge about the progress made in understanding the mechanisms of prion propagation, and to persons just beginning to study these unconventional, fatal brain diseases.
The ability of genetic background to influence prion strain selection together with knowledge of numerous other factors that may influence clinical and neuropathological presentation strongly emphasises the requirement to identify distinct human prion strains in appropriate transgenic models, where host genetic variability and other modifiers of phenotype are removed.
The urinary prion seems to be an excellent marker for the progression of prion diseases, Dr. Gabizon said.
