Abstract:

Accumulation of amyloid beta (Aβ) in the brain in Alzheimer disease drives pathophysiology. A study in this issue of PLOS Biology revealed that Aβ from the liver can promote brain pathology, supporting that peripheral Aβ can contribute to neurodegeneration.

Amyloid Fibrils

10.8K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...
