CPP reveals structural changes in the proteome in Alzheimer disease

Neurodegenerative diseases are characterized by an accumulation of misfolded proteins. Cells normally recognize misfolded proteins and attempt to refold or to pass them on for proteasomal degradation. Chaperone proteins are central to recognizing and in refolding client proteins. When chaperone proteins fail to fulfill this function, conformationally altered proteins accumulate and can cause cell death.
