In a comprehensive Genomic Press perspective article published today, researchers from Fudan University and Shanghai University of Traditional Chinese Medicine have highlighted remarkable advances in the development of positron emission tomography (PET) tracers capable of visualizing ?-synuclein aggregates in the brains of patients with Parkinson's disease and related disorders. The abnormal accumulation of ?-synuclein protein is a defining pathological feature of several neurodegenerative conditions collectively known as synucleinopathies, including Parkinson's disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies (DLB). Until recently, confirming the presence of these protein aggregates required post-mortem examination, severely limiting early diagnosis and treatment...
