Amyloid Beta Peptide Aggregation

Molecular classification
Peptide aggregation, Protein aggregation
01

Overview

Amyloid beta (Aβ) peptide aggregation refers to the process by which Aβ peptides self-associate into various aggregated forms, including oligomers, protofibrils, fibrils, and plaques. This process is a hallmark of Alzheimer's disease (AD), with the accumulation of Aβ aggregates, particularly in the form of amyloid plaques, contributing to neurotoxicity and cognitive decline. Small soluble oligomers are considered the most neurotoxic species. Inhibiting or modulating amyloid beta peptide aggregation is a major therapeutic strategy for AD.
