PPARG and ischemic stroke: We showed that Olig2-OPCs increased the gene expression of the PPARγ signaling pathway, and activated CEPT1-mediated phospholipogenesis, Strikingly, we also found that transplantation of Olig2-OPCs could enhance the recovery of learning and memory deficits by promoting neuron survival and increasing remyelination in rats with ischemic stroke.
