NEUROG2 and brain ischemia: We confirmed that the TAT‐LBD‐Ngn2 could attenuate cerebral ischemia‐reperfusion injury by inhibiting neuronal degeneration and apoptosis, and improve short‐term cognition by regulating caspase‐dependent and mitochondrial apoptotic pathways (Deng et al., 2013; Zhao et al., 2018).
