CSF immune activation in Alzheimer’s disease driven by tau‐ and not amyloid pathology

Genetic studies suggest involvement of the immune system in Alzheimer’s disease (AD) development, and neuroinflammation has been suggested as a key driver of AD. We here employ cerebrospinal fluid (CSF) markers to study whether immune‐ and glial activation are primary features of early amyloid plaque deposition, or follow significant tau pathology as the disease progresses.
