Prion spread at cellular level
Prion spread. Artwork of a theoretical basis for 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-Jakob disease) in humans. They cause fatal brain and nerve degeneration. A normal form of prion protein (tiny green balls,lower centre) is made with instructions from cell nuclei (brown,one at bottom right). The prions (pink balls,upper right) are a different shape of this normal prion protein,and cause the normal ones to flip to the abnormal shape. Spread may be by nerve cells (top left) & white blood cells (lower left)
