Abstract
The formation of the abnormal protease-resistant, amyloidogenic isoform of PrP (PrP-res) appears to play a central role in the pathogenesis of scrapie and other transmissible spongiform encephalopathies (TSEs). Thus, it is important to understand the process by which the normal, protease-sensitive PrP (PrP-sen) is converted to the protease-resistant state. To define the cellular and molecular details of this process and how it might be inhibited, we have performed in vitro studies using both scrapie-infected tissue culture cells and cell-free reactions. This chapter summarizes the recent results from these studies.
