Proteopathic Seeds and Neurodegenerative Diseases (Research and Perspectives in Alzheimer's Disease) by Mathias Jucker, Yves Christen

The misfolding and aggregation of specific proteins is an early and compulsory occasion in most of the age-associated neurodegenerative illnesses of humans. The initial cause of this pathogenic cascade and the means whereby disease spreads through the nervous system, stay uncertain. A current surge of research, first instigated by pathologic similarities between prion disease and Alzheimer’s disease, increasingly implicates the conversion of illness-specific proteins into an mixture-inclined b-sheet-wealthy state as the prime mover of the neurodegenerative process. This prion-like corruptive protein templating or seeding now characterizes such clinically and etiologically diverse neurological problems as Alzheimer´s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, and frontotemporal lobar degeneration. Understanding the misfolding, aggregation, trafficking and pathogenicity of the affected proteins could due to this fact reveal universal pathomechanistic rules for a number of the most devastating and intractable human brain disorders. It's time to settle for that the prion concept is now not confined to prionoses however is a promising idea for the understanding and remedy of a outstanding number of illnesses that afflict primarily our getting old society. ​
