WebPrions multiply in the lymphoreticular system, but this activity is not essential for neuroinvasion. The misfolded proteins aggregate into rod-shaped fibrils, and prions at the ends of the rods continue converting normal PrP into PrP Sc (Caughey, 2002). WebPrions are a distinct type of protein — they can self-replicate, said Adriano Aguzzi, professor of neuropathology at the University of Zurich, who led the study. When a prion comes into contact with a normal protein, it makes the normal protein alter its shape, and become a prion, too.
