| Outline of Final Research Achievements |
Neonatal hypoxic-ischemia is a condition that result in severe neurologic deficits in children. Periventricular leukomalacia (PVL), a brain hypoxic-ischemia affecting premature infants is commonly associated with cerebral palsy. A brain of premature infants is particularly susceptible to cerebral white matter injury that disrupts the normal progression of developmental myelination. In this study, we investigated pathogenesis of PVL using induced culture cells and animal models. While we are performing experiments, we found that (1) monoacylglycerol lipase (MAGL), an important factor in neuroinflammation, regulates phagocytosis, but not LPS-mediated cytokine induction in microglia. (2) Cholesterol trafficking in immature oligodendrocytes play an important role in maturation of the cells and myelination. These findings will provide a possible preventive approach for white matter injury in PVL.
