Prion spread at cellular level

Prion spread. Artwork of a theoretical basisfor the spread of prions at a cellular level.Prions are abnormal proteins that are the cause of transmissible spongiform encephalopathies (TSEs), such as BSE in cows, scrapie in sheep and CJD (Creutzfeldt-Jakobdisease) in humans. They cause fatal brain andnerve degeneration. A normal form of prion protein(tiny green balls, lower centre) is made withinstructions from cell nuclei (brown, one atbottom right). The prions (pink balls, upperright) are a different shape of this normal prionprotein, and cause the normal ones to flip to theabnormal shape. Spread may be by nerve cells (topleft) & white blood cells (lower left)
