Chinese Medical Team Makes Breakthrough in Prion Disease Diagnosis
Beijing, October17, 2024 – A research team led by ProfessorWu Liyong from Xuanwu Hospital of Capital Medical University, in collaboration with Professor Dong Xiaoping’s team from the Chinese Center for Disease Control and Prevention, hasmade significant progress in the diagnosis of prion diseases. Their findings were published in the renowned journal JAMA Neurology, marking a groundbreaking achievement in the field.
This research, the first of its kind globally, evaluated the effectiveness of real-time quaking-induced conversion (RT-QuIC) technology in diagnosing prion diseases using live skin samples. RT-QuIC is a highly sensitive andspecific technique that detects the misfolded prion proteins, which are the hallmark of prion diseases.
Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of fatal neurodegenerativedisorders that affect both humans and animals. These diseases are characterized by the accumulation of misfolded prion proteins in the brain, leading to severe neurological damage and ultimately death.
The current diagnostic methods for prion diseases are invasive and often require brain biopsies, which pose significant risks to patients. The development of a non-invasivediagnostic tool using skin samples has the potential to revolutionize prion disease diagnosis, enabling early detection and potentially leading to more effective treatment strategies.
Professor Wu Liyong, the lead researcher, emphasized the significance of this breakthrough, stating that this research provides a new avenue for diagnosing prion diseases in a non-invasivemanner, offering a safer and more convenient approach for patients.
The study involved a large cohort of patients with suspected prion diseases, and the results demonstrated a high degree of accuracy and sensitivity of the RT-QuIC technology using skin samples. The findings have significant implications for the early diagnosis and management of prion diseases,potentially improving patient outcomes and reducing the burden of these devastating disorders.
This research is a testament to the ongoing advancements in medical science in China, highlighting the country’s commitment to tackling challenging medical issues. The development of this non-invasive diagnostic tool for prion diseases is a significant step forward in the fight against thesedebilitating diseases.
