Imagine a detective who can use a special test to accurately identify and magnify the tracks left by a particular suspect at a crime scene. Researchers have developed a similar technique for diagnosing Parkinson’s disease (PD) called real-time quaking-induced conversion (RT-QuIC) assay. In this study, scientists used RT-QuIC to detect misfolded α-Syn protein, which is associated with PD, in both brain and skin tissues of Chinese patients. The results were highly specific, correctly identifying PD cases while producing negative results for healthy individuals. The RT-QuIC assay showed a dose-dependent relationship between the time it took for detection and the intensity of fluorescent signals, providing important quantitative information about the disease progression. The testing limit for brain tissue was 10^-7 dilution, meaning very small amounts of α-Syn could be detected. This breakthrough test opens up new possibilities for earlier and more accurate PD diagnosis, potentially leading to improved treatment outcomes.

The real-time quaking-induced conversion (RT-QuIC) assay has been developed and used as an in vitro diagnostic tool for Parkinson’s disease (PD). In this study, we established α-Syn RT-QuIC using recombinant human α-Syn as the substrate. All 5 brain homogenates of neuropathological PD cases and 13 skin homogenates of clinical PD cases showed positive results, whereas all the samples of negative controls remain negative. Meantime, randomly selected 6 skin samples of PD cases and 6 skin samples of sCJD cases showed negative in opposite prion RT-QuIC and α-Syn RT-QuIC. Our α-Syn RT-QuIC showed dose-dependent manner between the lag times and peak ThT fluorescent values. Additionally, the detecting limitation was about 10–7 dilution for brain tissues and 10–6 for skins. Those data indicate a reliable specificity and good sensitivity of the established α-Syn RT-QuIC in identifying and amplifying the misfolded α-Syn in brain and skin tissues of patients with PD.
