Key Points

The research aims to explore the relationship between tau-PET uptake and neuropathological findings in cases of glial tauopathy.
Case series analysis of glial tauopathy (GGT) cases
Histopathological examination to identify tau pathology
Autoradiographic analysis to assess uptake mechanisms
Flortaucipir uptake suggests possible underlying 4R tau presence
Autoradiographic analysis indicates off-target binding as a likely explanation
Need for larger cohorts to clarify the pathological basis of observed uptake

Abstract

Histopathologic findings suggest that some flortaucipir uptake in GGT may represent underlying 4R tau, whereas autoradiographic analysis suggests that uptake is likely due to off-target binding. Further studies with larger cohorts are needed to determine the pathological basis of flortaucipir uptake in GGT.
