Disease profile
A grounded synthesis of the condition — overview, causes, mechanism, risk factors and current standard of care.
Pathological protein aggregation is a biochemical process in which misfolded proteins accumulate as aggregates inside or outside cells. It is commonly associated with neurodegenerative and metabolic diseases, including Alzheimer disease, Parkinson disease, Huntington disease, and type 2 diabetes mellitus.
The grounding identifies mutation, post-translational modifications, and environmental stress as triggers for pathological protein aggregation. It also notes that oxidative stress can contribute to aggregation-related pathology in Alzheimer disease.
The core mechanism is failure of protein folding and quality control, allowing newly synthesized or otherwise stressed proteins to misfold and form toxic aggregate species. Molecular chaperones, protein degradation systems, and the unfolded protein response normally help maintain proteostasis, but this network declines with aging, facilitating aggregation and disease. The literature also describes aggregated species such as amyloid-beta and TDP-43, and in some settings prion-like spreading of misfolded aggregates between cells.
Aging is a major factor because proteostasis capacity declines over time, increasing susceptibility to protein misfolding and aggregation. Environmental stress and oxidative stress are also implicated, and mutation and post-translational modifications can increase risk by promoting misfolding.
