α-Synuclein Oligomers Induced by Docosahexaenoic Acid Affect Membrane Integrity

A key feature of Parkinson disease is the aggregation of α-synuclein and its intracellular deposition in fibrillar form. Increasing evidence suggests that the pathogenicity of α-synuclein is correlated with the activity of oligomers formed in the early stages of its aggregation process. Oligomers toxicity seems to be associated with both their ability to bind and affect the integrity of lipid m...

α-Synuclein: membrane interactions and toxicity in Parkinson's disease.

In the late 1990s, mutations in the synaptic protein α-synuclein (α-syn) were identified in families with hereditary Parkinson's disease (PD). Rapidly, α-syn became the target of numerous investigations that have transformed our understanding of the pathogenesis underlying this disorder. α-Syn is the major component of Lewy bodies (LBs), cytoplasmic protein aggregate...

Kinetic measurements give new insights into lipid membrane permeabilization by α-synuclein oligomers.

Interactions of oligomeric aggregates of the intrinsically disordered protein α-synuclein with lipid membranes appear to play an important role in the development of Parkinson's disease. The permeabilization of cellular membranes by oligomers has been proposed to result in neuronal death. The detailed mechanisms by which α-synuclein oligomers permeabilize lipid bilayers remain unknown. Two diff...

Sumoylation inhibits α-synuclein aggregation and toxicity

Posttranslational modification of proteins by attachment of small ubiquitin-related modifier (SUMO) contributes to numerous cellular phenomena. Sumoylation sometimes creates and abolishes binding interfaces, but increasing evidence points to another role for sumoylation in promoting the solubility of aggregation-prone proteins. Using purified α-synuclein, an aggregation-prone protein implicated...

Corrigendum: Structural basis of synaptic vesicle assembly promoted by α-synuclein

α-synuclein (αS) is an intrinsically disordered protein whose fibrillar aggregates are the major constituents of Lewy bodies in Parkinson's disease. Although the specific function of αS is still unclear, a general consensus is forming that it has a key role in regulating the process of neurotransmitter release, which is associated with the mediation of synaptic vesicle interactions and assembly...
