Neuroinflammation reveals amyloid and tau pathology in Alzheimer's disease spectrum, suggesting targeted therapy.

This research aims to understand the role of neuroinflammation in Alzheimer's disease and its correlation with amyloid and tau pathology.
Assessed TSPO expression in human microglia under inflammatory conditions using immunoblotting.
Enrolled 96 participants across four groups related to Alzheimer's disease.
Utilized 11C-ER176 PET to measure neuroinflammation and compare it with amyloid and tau PET.
Examined correlations between neuroinflammation and Alzheimer’s pathology across different disease stages.
TSPO expression increased in microglia under AD-like inflammatory conditions.
Neuroinflammation was significantly higher in amyloid-positive individuals, especially during mild cognitive impairment.
Findings show a stronger relationship between neuroinflammation and tau pathology in specific brain regions.
Neuroinflammation became more widespread with the severity of Alzheimer's disease.
