Project description:In this study we identified genes differentially expressed in the central nervous system (CNS) of mice during infection with mouse-adapted scrapie agents. We used cDNA microarrays to examine gene expression profiles at early, mid (pre-clinical) and late (clinical) time points after inoculation. Keywords = scrapie Keywords = prion Keywords = CNS Keywords = BMAP Keywords: other

Project description:Sheep scrapie is a transmissible spongiform encephalopathy (TSE), which are invariably fatalM- 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.

Susceptible VRQ homozygous New Zealand Cheviot sheep were infected with SSBP/1 scrapie by inoculation in the drainage area of the prescapular lymph nodes. PrPSc was consistently detected by immunohistology in the CNS at 125 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 (75dpi) and at the time point when PrPSc is consistently detected in the CNS (125 dpi).
Project description: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. For many transmissible spongiform encephalopathies (TSEs), peripheral lymphoid tissue is an important site of PrPSc amplification but without obvious immunological consequence. Susceptible VRQ homozygous New Zealand Cheviot sheep were infected with SSBP/1 scrapie by inoculation in the drainage area of the prescapular lymph nodes. PrPSc was consistently detected by immunohistology in these nodes at 50 days post infection (dpi). This study compares the genes and physiological pathways that are affected by the progression of TSE disease in the prescapular lymph nodes, focussing on time points immediately before (10 dpi) and after (50 dpi) the detection of disease-associated PrPSc.
