The fibroblast activation protein (FAP) is a known biomarker expressed on the surface of cancer-associated fibroblasts (CAF), as well as an important target that distinguishes normal fibroblasts from CAF. Researchers from National Yang-Ming University recently reported the discovery and preclinical evaluation of a novel PET tracer, [18F]FEQGP, being developed for the detection of FAB expression in CAF imaging.
Four-repeat (4R)-tauopathies are neurodegenerative diseases whose main hallmarks are brain accumulations of specific protein tau isoforms that lead to syndromes such as progressive supranuclear palsy (PSP) or corticobasal syndrome. There are yet no sensitive-enough PET tracers for 4R-tauopathies.
AC Immune SA has patented 4h-imidazo[1,5-b]pyrazole derivatives and labeled compounds targeting α-synuclein (SNCA). They are reported to be useful for diagnosis of multiple system atrophy, Parkinson’s dementia, Lewy body dementia, Alzheimer’s and Parkinson’s disease, among others.
α-Synucleinopathies constitute a set of neurological disorders including Parkinson’s disease (PD), dementia with Lewy bodies, multiple systems atrophy (MSA), and other rare disorders. The development of positron emission tomography (PET) tracers for imaging α-synuclein aggregates is essential for performing efficient and accurate diagnosis, tracking disease progression and monitoring efficacy of potential therapies.
Previous studies have identified a promising target and potential biomarker for diagnosing and treating gastrointestinal and esophageal cancers: claudin18.2 (CLDN18.2), a tight junction protein overexpressed in these and other solid tumors.
Theranocure Co. Ltd. has divulged gadolinium complexes targeting β-amyloid protein acting as magnetic resonance imaging (MRI) contrast agents reported to be useful for the diagnosis of Alzheimer's disease and the treatment of Parkinson's and Alzheimer's disease.
Researchers at Stanford University School of Medicine have developed a method to measure several thousand metabolites, including proteins, metabolites, inflammatory markers such as cytokines and, to a degree, lipids. “It’s like Theranos, except it works,” corresponding author Michael Snyder, director of the Center for Genomics and Personalized Medicine at Stanford Medicine, told BioWorld.
