The deposition of α-synuclein (α-syn) fibrils in Lewy bodies is a characteristic feature of individuals with neurodegenerative disorders. The central hydrophobic region of α-synuclein, resembled by the peptide α-synuclein (71-82), is believed to be responsible for the protein aggregation. In addition, α-synuclein (71-82) forms amyloid fibrils of similar morphology to α-synuclein, suggesting that this region contributes to the fibrillogenic core of the full-length protein, referring to the studies of Madine and coworkers.
