The neurobiology of Alzheimer's disease (AD) is unclear due to its multifactorial nature. Although a wide range of studies revealed several pathomechanisms of AD, dementia is yet unmanageable with current pharmacotherapies. The recent growing literature illustrates the role of microglia-mediated neuroinflammation in the pathogenesis of AD. Indeed, microglia serve as predominant sentinels of the brain, which diligently monitor the neuroimmune axis by phagocytosis and releasing soluble factors. In the case of AD, microglial cells are involved in synaptic pruning and remodeling by producing inflammatory mediators. The conditional inter-transformation of classical activation (proinflammatory) or alternative activation (anti-inflammatory) microglia is responsible for most brain disorders. In this review, we discussed the role of microglia in neuroinflammatory processes in AD following the accumulation of amyloid-β and tau proteins. We also described the prominent phenotypes of microglia, such as disease-associated microglia (DAM), dark microglia, interferon-responsive microglia (IRMs), human AD microglia (HAMs), and microglial neurodegenerative phenotype (MGnD), which are closely associated with AD incidence. Considering the key role of microglia in AD progression, microglial-based therapeutics may hold promise in mitigating cognitive deficits by addressing the neuroinflammatory responses.
