Differential gene expression in CNS after scrapie infection


ABSTRACT: Sheep scrapie is a transmissible spongiform encephalopathy (TSE), which are invariably fatal neurodegenerative diseases of the central nervous system (CNS). Accumulation of the misfolded prion protein, PrPSc in the CNS results in progressive neurodegenerative disease. Susceptible VRQ homozygous New Zealand Cheviot sheep were infected with standard scrapie sheep prion (SSBP/1) scrapie by inoculation in the drainage area of the prescapular lymph nodes. PrPSc was consistently detected by immunohistology in the CNS at XX days post infection (dpi). This study compares the genes and physiological pathways that are affected by the progression of TSE disease in the CNS, focusing on time points immediately before (XX dpi) and after (XX dpi) the detection of disease-associated PrPSc.

Sheep scrapie is a transmissible spongiform encephalopathy (TSE), progressive and fatal neurodegenerative diseases of the central nervous system (CNS) linked to the accumulation of misfolded prion protein, PrP(Sc). New Zealand Cheviot sheep, homozygous for the VRQ genotype of the PRNP gene are most susceptible with an incubation period of 193 days with SSBP/1 scrapie. However, the earliest time point that PrP(Sc) can be detected in the CNS is 125 days (D125). The aim of this study was to quantif  ...[more]
