TREM2 and vascular dementia: Subsequent experiments confirmed that EEGE effectively downregulated serum levels of IL-6, TNF-α, and IL-1β by modulating the IGF1-TREM2 signaling axis and the AMPK-SIRT1-FoxO1-NF-κB pathway.<h4>Conclusion</h4>The improvement of cognitive dysfunction in vascular dementia by EEGE is closely associated with its regulation of the IGF1-TREM2 axis and the AMPK-SIRT1-FoxO1-NF-κB pathway, thereby mitigating neuroinflammation.
