Current Landscape of Glycogen Synthase Kinase-3β PET Tracers: Progress, Limitations, and Perspectives—A Narrative Review
Background/Objectives: Glycogen synthase kinase-3β (GSK-3β) serves as a crucial molecular target for Alzheimer’s disease and other neurological disorders. Positron emission tomography (PET) enables non-invasive quantification of GSK-3β in vivo, offering value for early diagnosis and mechanistic studies. However, despit...
