Outline of Final Research Achievements

Hypoxic ischemic encephalopathy (HIE) in neonates is a leading cause of neurological impairment. We investigated the function of the prostaglandin in rodent models of neonatal HIE and human induced pluripotent stem cells (iPSCs). Pharmacologic activation of the EP4 receptor with a selective agonist (AE1-329) was significantly cerebroprotective through the improvement of cerebral perfusion. On the other hand, activation of EP2-4 receptors with the agonist misoprostol significantly reduced the oxidative stress in human iPSC-derived neural precursors subjected to oxygen glucose deprivation. These data indicate that the G-protein coupled EP receptors may be amenable to pharmacologic targeting in the acute setting of neonatal HIE.
