After transport through the intestinal mucosa, PrP Sc particles are captured by several types of cells including macrophages, lymphocytes and dendritic cells DCs and presented to follicular dendritic cells FDCs in the lamina propia. In vitro generation of infectious scrapie prions. The used sources of information were medical records and results of arterial gasometry.

One of these theories postulates the inter-species transmission from scrapie-infected sheep to cattle. During the last years, substantial efforts have been applied in the development of PrP Sc -specific antibodies for the potential diagnostic of infectivity in fluids and tissues.
