Alpha-synuclein Aggregates (α-syn Aggregates)

Target
α-syn Aggregates
Molecular classification
Protein Aggregate, Intracellular Inclusion
01

Overview

Alpha-synuclein aggregates are pathological accumulations of the alpha-synuclein protein, playing a central role in the development of Parkinson's disease and other synucleinopathies. These aggregates, including oligomers, protofibrils, and fibrils, disrupt cellular function and contribute to neurodegeneration. Targeting these aggregates is a major therapeutic strategy for these diseases.

Mechanism of action

Targeting alpha-synuclein aggregates aims to reduce aggregate formation, promote aggregate clearance, or mitigate downstream toxicity. Strategies under investigation include small molecule inhibitors, antibodies, and gene therapies.
