Abstract
Microglia are associated with multiple mechanisms of dysfunction in Alzheimer's disease.
- Microglia contribute to breakdown through neuroinflammation and oxidative stress.
- They induce mitochondrial dysfunction in neurons, affecting energy balance and cellular health.
- Microglia can promote abnormal contraction of cerebral vessels and loss of pericytes in Alzheimer's disease.
- Dysfunction in astrocytes and pericytes, mediated by microglia, may compromise the integrity of the neurovascular unit.
- Therapeutic advancements are being explored to restore microglial and neurovascular unit functions in Alzheimer's disease.
