Abstract

(ZGP) treatment for 60 days significantly improved cognitive performance in a transgenic Alzheimer's disease mouse model.

  • ZGP treatment reduced hippocampal amyloid-β deposition and BACE1 expression.
  • Suppression of tau phosphorylation was observed at multiple pathological sites (T205, S396, S404).
  • Restoration of synaptic markers and increased dendritic spine density were noted.
  • ZGP decreased levels of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α in the hippocampus.
  • Inhibition of the RAGE/NF-κB signaling pathway was associated with neuroinflammation reduction.
