Zhang et al. [28] confirmed through in vitro and in vivo experiments that Cyanidin-3-O-glucoside can alleviate Aβ25-35-induced damage of SH-SY5Y cells through the PPARγ pathway and increase the cognitive ability of APPswe/PSEN1dE9 double transgenic AD mice in a novel object recognition experiment. Here, PPARG is linked to Alzheimer disease.
