RNA-seq of coding RNA of peripheral lymphoid tissue immediately before and after the detection of PrPSc in sheep scrapie


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. 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.
