Discovery of the day
Researchers have developed a novel positron emission tomography (PET) tracer, [18F]JNJ-TDP43-1, designed to specifically bind to pathological TDP-43 aggregates, a proteinopathy central to several neurodegenerative diseases including ALS, frontotemporal dementia, and a subset of Alzheimer’s disease. The tracer demonstrated a high binding affinity for pathological TDP-43 (Kd = 7.1 nM) with remarkable selectivity over other proteinopathies, and PET imaging in rodents and nonhuman primates confirmed robust brain uptake, rapid washout, and in vivo target engagement in an AAV-hTDP43 disease model. For a neuroscientist developing preclinical models of pain and placebo mechanisms, this tool offers a powerful method to study protein aggregation in living brains, potentially enabling earlier diagnosis and therapeutic monitoring in the neurodegenerative conditions that intersect with chronic pain pathways.
