Toxicity of extracellular alpha-synuclein is independent of intracellular alpha-synuclein
Scientific Reports, 2022 Abstract Parkinson′s disease (PD) pathology progresses throughout the nervous system affecting numerous neuronal structures. It has been postulated that the progression of the pathology is based on a prion-like disease mechanism partly due to the seeding effect of endocytosed alpha-synuclein (ASYN) on the endogenous ASYN. The appearance

The Membrane Interaction of Alpha-Synuclein [PDF]
Frontiers in Cellular Neuroscience, 2021 A presynaptic protein closely related to Parkinson's disease (PD), α-synuclein (α-Syn), has been studied extensively regarding its pathogenic mechanisms. As a physiological protein in presynapses, however, α-Syn's physiological function remains unclear.

SUMOylation of Alpha-Synuclein Influences on Alpha-Synuclein Aggregation Induced by Methamphetamine [PDF]
Frontiers in Cellular Neuroscience, 2018 Methamphetamine (METH) is an illegal and widely abused psychoactive stimulant. METH abusers are at high risk of neurodegenerative disorders, including Parkinson's disease (PD). Previous studies have demonstrated that METH causes alpha-synuclein (α-syn) aggregation in the both laboratory animal and human.

Mitochondrial localization of alpha-synuclein protein in alpha-synuclein overexpressing cells [PDF]
Neuroscience Letters, 2008 Alpha-synuclein (alpha-syn) is implicated in the pathogenesis of Parkinson's disease (PD). Mutations in alpha-syn gene or alpha-syn locus (SNCA) triplication are associated with mitochondrial abnormalities and early onset of familial PD. The goals of the present study were to examine whether alpha-syn is localized in the mitochondria of alpha-syn ...

Gastrointestinal Immunity and Alpha-Synuclein [PDF]
Journal of Parkinson’s Disease, 2019 The gastrointestinal (GI) tract is equipped with robust immune defenses which protect the organism from infection. Enteric nerves are front and center in this defensive network, even in the most primitive organisms. Neuropeptides exhibit potent antimicrobial activity in the vicinity of the nerve and attract the innate and adaptive immune systems to ...

Alpha synuclein and inflammaging
HeliyonThe α-synuclein protein is an established molecule in Lewy body pathology, especially Parkinson's disease (PD). While the pathological role of α-synuclein (α-syn) in PD has been well described, novel evidence may suggest that α-syn interacts with inflammasomes in response to aging.

Alpha-Synuclein FRET Biosensors Reveal Early Alpha-Synuclein Aggregation in the Endoplasmic Reticulum [PDF]
Life, 2020 Endoplasmic reticulum (ER) dysfunction is important for alpha-synuclein (αS) acquired toxicity. When targeted to the ER in SH-SY5Y cells, transient or stable expression of αS resulted in the formation of compact αS-positive structures in a small subpopulation of cells, resembling αS inclusions. Thus, because of the limitations of immunofluorescence, we

Alpha Synuclein: Neurodegeneration and Inflammation
International Journal of Molecular Sciences, 2023 Alpha-Synuclein (α-Syn) is one of the most important molecules involved in the pathogenesis of Parkinson’s disease and related disorders, synucleinopathies, but also in several other neurodegenerative disorders with a more elusive role. This review analyzes the activities of α-Syn, in different conformational states, monomeric, oligomeric and fibrils ...

Intercellular transmission of alpha-synuclein [PDF]
Frontiers in Molecular NeuroscienceAn emerging theme in Parkinson’s disease (PD) is the propagation of α-synuclein pathology as the disease progresses. Research involving the injection of preformed α-synuclein fibrils (PFFs) in animal models has recapitulated the pathological spread observed in PD patients.

Alpha-synuclein spreading in Parkinson’s disease [PDF]
Frontiers in Neuroanatomy, 2014 Formation and accumulation of misfolded protein aggregates are a central hallmark of several neurodegenerative diseases. In Parkinson's disease (PD), the aggregation-prone protein alpha-synuclein (α-syn) is the culprit. In the past few years, another piece of the puzzle has been added with data suggesting that α-syn may self-propagate, thereby ...
