Comparison of the mean fluorescence intensity ratio of different types of α-synuclein in sigmoid. a OSyn/αSyn in sigmoid mucosa; b OSyn/PSyn in sigmoid mucosa; c PSyn/αSyn in sigmoid mucosa; d OSyn/αSyn in duodenum mucosa; e OSyn/PSyn in duodenum mucosa; f PSyn/αSyn in duodenum mucosa. n = 7–21; ns P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001,****P<0.0001. PD: Parkinson’s disease; OSyn/αSyn: oligomer α-synuclein/total α-synuclein; OSyn/PSyn: oligomer α-synuclein/phosphorylate α-synuclein; PSyn/αSyn: phosphorylate α-synuclein/total α-synuclein
