[A review on the relationship between mitochondrial dysfunction and white matter injury in preterm infants].

White matter injury in preterm infants has a complex etiology and can lead to long-term neurocognitive and behavioral deficits, but there are still no specific treatment methods for this disease at present. More and more studies have shown that mitochondrial dysfunction plays an important role in the pathogenesis of white matter injury in preterm infants and might be a common subcellular mechanism of white matter developmental disorder, which involves oxidative stress, reduced ATP synthesis, and disequilibrium of calcium homeostasis. This article reviews the role of mitochondria in brain development and the mechanism of mitochondrial dysfunction, with a hope to perform early intervention of white matter injury in preterm infants by protecting mitochondrial function, so as to provide a reference for improving the neurodevelopmental outcome of preterm infants who survive.
