In an extensive genomic perspective article that was published today, researchers from Fudan University and Shanghai University of Traditional Chinese medicine have emphasized remarkable progress in the development of Positron Emission Tomography (PET) Tracers who are able to visualize α-Synucleinaggregates in the brains and in the diseases in the brain.
The abnormal accumulation of A-Synuclein protein is a determining pathological feature of various neurodegenerative disorders that are jointly known as Synucleinopathies, including Parkinson’s Disease (PD), multiple system atrophy (MSA) and dementia with Lewy-Lichagen. Until recently, the confirmation of the presence of these protein aggregates required post-mortem examination, which seriously limited the early diagnosis and the monitoring monitoring options.
“The ability to visualize these protein aggregates in living patients is an important leap forward in research into neurodegenerative diseases,” says Dr. Fang Xie from, corresponding author and researcher at the Department of Nuclear Medicine & Pet Center of Huashan Hospital, Fudan University.
A suitable radio racer who can not map out -invasive synucleinopathies through PET image formation will lead to breakthroughs in early diagnosis, monitoring disease progression and evaluating treatment reactions. “

The perspective article carefully assesses recent developments in the development of PET Tracer, with special attention to promising candidates who have shown effectiveness in both laboratory and clinical environments. The researchers emphasize tracers such as [18F]F-0502B, [18F]C05-05, and [18F]ACI-12589, who have demonstrated encouraging results in distinguishing patients with synucleinopathies of healthy checks.
A particularly important breakthrough came then [18F]C05-05 Visualized Synucleinopathies with ten patients who meet the clinical diagnostic criteria for Parkinson’s disease or dementia with lewy bodies. This tracer displayed raised binding in the middle brain area that is often influenced by Lewy Body Pathologies and this binding correlated well with the severity of motor symptoms.
Another promising tracer, [18F]ACI-12589, developed by the biotech company AC Immuun, has shown remarkable results in distinguishing multiple system atrophy from other neurodegenerative diseases. This radio tracer showed a greater retention in the cerebellar white fabric from MSA patients compared to patients with PD, DLB or healthy checks.
Despite these encouraging developments, the authors recognize various challenges that remain in the development of optimum PET-PET tracers of the Aynuclein. The heterogeneous distribution and conformation of α-synuclein aggregates on different synucleinopathies, along with the relatively low density of these pathological characteristics, complicating the development of universally effective imaging agents.
The clinical implications of these progress go beyond the diagnosis. Can these image tools ultimately help stratify patients for clinical studies based on their specific pathological profiles? Could they serve as critical biomarkers for assessing the efficacy of emerging disease-modifying treatments aimed at A-Synuclein aggregation? These questions emphasize the potential far-reaching impact of this technology on personalized medicine approaches of neurodegenerative disorders.
“The field moves fast and we witness the translation of laboratory discoveries into clinical applications,” notes Dr. Yingfang he, main author of the Institute of Radiation Medicine at Fudan University. “What makes these developments particularly exciting is their potential to transform how we diagnose and treat these devastating disorders, possibly intervening before irreversible neurodegeneration occurs.”
As the world’s population gets older, the prevalence of neurodegenerative disorders is expected to rise dramatically. The development of reliable imaging biomarkers for Synucleinopathies can significantly influence both clinical management and research efforts aimed at developing disease -modifying therapies.
