    Molecular docking models of Astragaloside IV (AS-IV) binding to the core targets. Representative binding poses of AS-IV (shown in stick representation) within the predicted binding pockets of the key target proteins. The calculated binding free energy (kcal/mol) for each complex is indicated.

    Figure Lengend Snippet: Age was not associated with any of the brain protein loads in the DS and DSAD groups. In the controls, we found associations between age and LepR ( p = 0.01), pSTAT3‐727 ( p = 0.04), and pSTAT3‐705 ( p = 0.002).
