The effect of microglial DMT1 inhibition on neuroinflammation in male and female mice

Neuroinflammation and microglial activation are critical components of Alzheimer’s Disease neuropathology as observed in patients and animal models. Microglia have multiple functions in addition to their inflammatory phenotype that can contribute to disease. Specifically, iron accumulates in AD‐associated brain regions, and we and others have shown enhanced iron load in activated microglia surrounding amyloid‐beta (Aβ) plaques. Furthermore, we and others have shown a distinct upregulation in the microglial iron importer, divalent metal transporter 1 (DMT1) in response to Aβ. Our aim is to further elucidate the role of microglial iron‐handling in age and AD‐associated inflammation.
