Levetiracetam, an antiepileptic drug has neuroprotective effects on intracranial hemorrhage injury

Publication date: Available online 11 February 2020Source: NeuroscienceAuthor(s): Takahiko Imai, Tomoki Sugiyama, Sena Iwata, Shinsuke Nakamura, Masamitsu Shimazawa, Hideaki HaraAbstractIntracranial hemorrhage (ICH) is a devastating disease that induces hematoma formation with poor neuronal outcome. Levetiracetam (LEV) has been approval for epilepsy seizures. In a previous study, LEV exerted protective effects on cerebral ischemia models; however, the detail effects and the influence of LEV on ICH are still unknown. The aim of this study was to investigate whether oral administration of LEV (50 or 150 mg/kg) has protective effects on ICH injury using both in vivo and in vitro experiments.In in vivo experiments, we utilized ICH models induced by autologous blood (bICH) or collagenase (cICH) injection. Moreover, we established a neuronal injury model using SYSH5Y human neuroblastoma cell lines. In the bICH model, frequently oral administration of LEV attenuated both cerebral edema and neurological deficits. In addition, the expression levels of phosphorylation-extracellular signal‑related kinase (ERK) 1/2 and cleaved caspase-7 were increased after ICH, and LEV suppressed such alterations. In in vitro experiments, hematoma releasing factors, such as hemoglobin (Hb) and hemin, induced neuronal cell death, and LEV treatment attenuated neuronal injury in a dose-dependent manner. In the cICH model, neurological deficits induced by extensive hematoma formation were attenuated by LE...

Innate immune responses are critical in stroke pathophysiology, and microglia are key cellular effectors in the CNS response to ischemia/reperfusion. Using a transcriptional analysis approach, we identified a robust interferon (IFN)-stimulated gene res...
