2019-11-08 · The abnormal prion proteins then aggregate to form clumps, which are deposited throughout the nervous system where they induce cell death and cause the brain to have a sponge-like appearance.

Prions are self-propagating protein conformations. Recent research brought insight into prion propagation, but how they first appear is unknown. We pr… Request PDF | Nucleation seed size determines amyloid clearance and establishes a barrier to prion appearance in yeast | Amyloid appearance is a rare event that is promoted in the presence of Figure: Prion-affected tissue: This micrograph of brain tissue reveals the cytoarchitectural histopathologic changes found in bovine spongiform encephalopathy. The presence of vacuoles, i.e. microscopic “holes” in the gray matter, gives the brain of BSE-affected cows a sponge-like appearance when tissue sections are examined in the lab.

When extrinsic abnormal prions are introduced into the body, they interact with normal indigenous prions and cause them to change their conformation into abnormal. The prion form of HET-s spreads rapidly throughout the cellular network of a colony and can convert the non-prion form of the protein to a prion state after compatible colonies have merged. However, when an incompatible colony tries to merge with a prion-containing colony, the prion causes the "invader" cells to die, ensuring that only related colonies obtain the benefit of sharing resources.
