abstract = {2-Deoxy-2-[18F]fluoro-d-glucose positron emission
tomography (FDG-PET) is widely used to study cerebral
glucose metabolism. Here, we investigated whether the
FDG-PET signal is directly influenced by microglial glucose
uptake in mouse models and patients with neurodegenerative
diseases. Using a recently developed approach for cell
sorting after FDG injection, we found that, at cellular
resolution, microglia displayed higher glucose uptake than
neurons and astrocytes. Alterations in microglial glucose
uptake were responsible for both the FDG-PET signal decrease
in Trem2-deficient mice and the FDG-PET signal increase in
mouse models for amyloidosis. Thus, opposite microglial
activation states determine the differential FDG uptake.
Consistently, 12 patients with Alzheimer’s disease and 21
patients with four-repeat tauopathies also exhibited a
positive association between glucose uptake and microglial
activity as determined by 18F-GE-180 18-kDa translocator
protein PET (TSPO-PET) in preserved brain regions,
indicating that the cerebral glucose uptake in humans is
also strongly influenced by microglial activity. Our
findings suggest that microglia activation states are
responsible for FDG-PET signal alterations in patients with
neurodegenerative diseases and mouse models for amyloidosis.
Microglial activation states should therefore be considered
when performing FDG-PET.},
