RNA-Seq of human primary microglial cells treated with vehicle or human paired helical filaments (PHFs) purified from human tauopathy autopsy brain

Neuroinflammation is one of the major neuropathological hallmarks of Alzheimer's disease (AD) and related tauopathies. Activated microglia often co-exist in the same brain regions where tau protein accumulates as hyperphosphorylated and aggregated PHFs or neurofibrillary tangles (NFTs) within neurons in patients with AD and related tauopathies. However, the exact mechanisms how pathological tau could induce neuroinflammatory responses are not clear. In this study, we treated primary human microglia with purified human PHFs and performed RNA-sequence analysis.
