Nrf2 Deficiency Exacerbates Cognitive Impairment and Reactive Microgliosis in a Lipopolysaccharide-Induced Neuroinflammatory Mouse Model.

ABSTRACT: The transcription factor Nrf2 is a central regulator of anti-inflammatory and antioxidant mechanisms that contribute to the development and progression of various neurological disorders. Although the direct and indirect Nrf2 regulatory roles on inflammation have been reviewed in recent years, the in vivo evidence of Nrf2 function on lipopolysaccharide (LPS)-induced cognitive decline and characteristic alterations of reactive microglia and astrocytes remains incomplete. During the 3-5 days after LPS or saline injection, 5-6-month-old wildtype (WT) and Nrf2^-/- C57BL/6 mice were subjected to the novel object recognition task. Immunohistochemistry staining was employed for analyses of brain cells. The Nrf2^-/- mice displayed exacerbated LPS-induced cognition impairment (28
