Gastrointestinal dysfunctions represent one of the main non-motor symptoms in Parksinon’s disease (PD). Prof. Angelo Antonini (Professor of Neurology, University of Padua, Padua, Italy) discusses a study that investigated α-Synuclein seeding activity in stomach-duodenum biopsies of PD patients by real-time quaking induced conversion (RT-QuIC) assay. The results suggest a deeper investigation in detection of α-Synuclein seeding activity in the early stages of PD in gastrointestinal biopsies via RT-QuIC as an early biomarker of disease.
The abstract entitled: ‘Detection of α-Synuclein Seeding Activity by RT-QUIC Assay in Gastrointestinal Biopsies of Patients with Advanced Parkinson’s Disease’ was presented at the International Conference of Alzheimer’s and Parkinson’s diseases and related neurological disorders (AD/PD), 13-15 October 2021.
