Nitrosative and oxidative injury to premyelinating oligodendrocytes in periventricular leukomalacia.
Periventricular leukomalacia (PVL), the major substrate of cerebral palsy in survivors of prematurity, is defined as focal periventricular necrosis and diffuse gliosis in immature cerebral white matter. We propose that nitrosative and/or oxidative stress to premyelinating oligodendrocytes complicating cerebral ischemia in the sick premature infant is a key mechanism of injury interfering with m...
متن کاملOxidative injury in the cerebral cortex and subplate neurons in periventricular leukomalacia.
We previously identified immunocytochemical evidence of nitrative and oxidative injury in premyelinating oligodendrocytes in periventricular leukomalacia (PVL). Here, we tested the hypothesis that free radical injury occurs in the overlying cerebral cortex and subplate neurons in PVL. We immunostained for nitrotyrosine, malondialdehyde, and hydroxynonenal adducts and scored neuron staining dens...
متن کاملAnimal Models of Periventricular Leukomalacia
Periventricular leukomalacia, specifically characterized as white matter injury, in neonates is strongly associated with the damage of pre-myelinating oligodendrocytes. Clinical data suggest that hypoxia-ischemia during delivery and intrauterine or neonatal infection-inflammation are important factors in the etiology of periventricular leukomalacia including cerebral palsy, a serious case exhib...
متن کاملMouse Models of Periventricular Leukomalacia
We describe a protocol for establishing mouse models of periventricular leukomalacia (PVL). PVL is the predominant form of brain injury in premature infants and the most common antecedent of cerebral palsy. PVL is characterized by periventricular white matter damage with prominent oligodendroglial injury. Hypoxia/ischemia with or without systemic infection/inflammation are the primary causes of...
متن کاملPontine hypoplasia in children with periventricular leukomalacia.
BACKGROUND AND PURPOSE The brain stem in patients with periventricular leukomalacia (PVL) appears smaller than normal on MR imaging, but few reports have described this feature, and the number of patients has been relatively small. The present study was conducted to examine the hypothesis that the pons in patients with PVL is smaller than normal. MATERIALS AND METHODS Using MR imaging, we exa...
