Implication

Overexpressing SOD2 in astrocytes mitigates cognitive impairment and cellular senescence, suggesting therapeutic potential.

Key Points

  • aSOD2OE significantly enhanced spatial working memory performance in aged mice, indicating cognitive benefits.
  • Molecular analysis revealed reduced markers of cellular senescence and reactive gliosis following SOD2 elevation.
  • AAV(PHP.eB)-GFAP-hSOD2 viral vector was used to target SOD2 overexpression in astrocytes of aged mice for assessment.
  • This research highlights astrocyte redox biology as a key therapeutic avenue for age-related cognitive decline.
