PRMT8 and ischemic stroke: Similarly, protein arginine methyltransferase 8 (PRMT8) is downregulated in ischemic stroke models, thus continuous AAV‐PRMT8 injection into the lateral ventricle of tMCAO mice for 7 days not only upregulated Lin28a but also promoted M2 polarization of microglia and neuronal survival, and improved histopathological changes in the brain.51
