ENO2 and ischemic stroke: The aim of this study was to determine age-dependent features of neuronal metabolism and cellular degradation in ischemic stroke based on immunohistochemical assessment of NeuN, NSE, and Caspase-3 markers in human cerebral cortex neurons, as well as to conduct a comparative analysis of gene expression in the PI3K/Akt/mTOR and PI3K/Akt/FOXO3a signaling pathways involved in the regulation of neuronal survival and apoptosis.
