The engagement of microglia in tau-targeted immunotherapy in Alzheimer's disease.

Alzheimer's disease (AD) is an age-related neurodegenerative disease characterized by progressive memory decline, histopathological lesions such as amyloid β plaques and neurofibrillary tangles, and neuroinflammation driven by glial cells. Microglia, the innate immune cells of the brain, dynamically survey their environment for signs of infection and cell damage. Although our understanding of microglia and their modes of activation has expanded in recent years, their role in AD is still not completely understood.
