Abstract

Microglia are key mediators of neuroinflammation and may be influenced by circadian rhythms.

  • Microglia respond to immune pathogens and toxins, playing a role in clearing debris and regulating brain function.
  • They are involved in phagocytosing amyloid-β plaques, which are linked to Alzheimer's disease.
  • Circadian clock genes are associated with the regulation of microglial functions, including phagocytosis.
  • Disruption of circadian rhythms may correlate with the progression of Alzheimer's disease.
  • Potential therapeutic targets include hormone modulation and lifestyle interventions to support brain health.
