The YHG ameliorates cognitive dysfunction and attenuates synaptic impairment in APP/PS1 mice. The underlying mechanism may involve the inhibition of GSK-3β activity, which subsequently activates PGC-1α-mediated mitochondrial biogenesis, enhances mitochondrial quality, and mitigates oxidative stress, ultimately leading to the restoration of synaptic structural integrity.
Zhong et al. (Fri,) studied this question.
