Interaction of alpha-synuclein (aSyn) with physiological lipid membranes leads to the disintegration of membranes, incorporation of lipids by aSyn fibrils, increased aggregation rate of aSyn fibrils, and increased uptake of lipid-associated fibrils compared to aSyn only fibrils into neurons....
The presence of 伪SN fibrils indisputably associates with the development of synucleinopathies. However, while certain fibril morphologies have been linked to downstream pathological phenotypes, others appear less harmful, leading to the concept of fibril strains, originally described in relation to prion...
Related to Alpha synuclein:Lewy bodies al·pha-sy·nu·cle·in (ăl′fə-sĭ-no͞o′klē-ĭn, -nyo͞o′-) n. A polypeptide protein found primarily in brain neurons but seen also in the fibrils in Parkinson's disease, in the amyloid plaques of Alzheimer's disease, and in br...
fragments might trigger the conversion of endogenous FL-αSyn into fragmented forms containing only the epitope of the seed. A similar scenario has been observed with fibrils produced with C-terminally truncated αSyn that activated caspase 1, which in turn converted endogenous FL-αSyn into the ...
α-Synuclein (αS) is a presynaptic small protein that has attracted much interest because its aggregation and accumulation in the form of amyloid fibrils is the hallmark of a range of neurodegenerative disorders, collectively referred to as synucleinopathies. Despite intense research on this protein...

Alpha-synuclein (α - syn) and tau polymerize into amyloid fibrils and form intraneuronal filamentous inclusions characteristic Of neurodegenerative diseases. We demonstrate that α - syn induces fibrillization of tau and that coin Fibrillization of both proteins. The in vivo rele cubation of tau and...
The following year, the basic structure of the protein fibrils was shown to be a β-pleated sheet [9]. We shall henceforth refer to such fibrils as amyloids. Since then, numerous reports, using high resolution techniques like cryo-electron microscopy (Cryo-EM), solid state nuclear magnetic ...
16 Deletion or disruption of this domain blocks the capacity of aSyn to form amyloid fibrils. The process of aSyn aggregation (Figure 1) has been studied in detail in an attempt to identify the toxic species responsible for neuronal dysfunction and death. However, it is still unclear what is...
(bottom). Monomeric α-Synuclein was used as control. The assays were performed in triplicate. (c) Electron microscopy images of negatively stained samples of the different types of α-Synuclein to confirm the presence of fibrils compared to the monomeric non-fibrilar α-Synuclein.Scale bar, ...
