Do white cells matter in white matter damage?
Support is provided for the hypothesis that activated leukocytes, especially monocytes/macrophages, contribute to cerebral white matter damage in extremely low gestational age newborns. Much of the evidence is indirect and comes from analogies to brain diseases in adults, and from models of brain damage in adult and newborn animals. If the recruitment of circulating cells to the brain contributes to white matter damage in extremely low gestational age newborns, then minimizing the transendothelial migration of circulating cells by pharmacological manipulation might prevent or reduce the occurrence of neonatal white matter damage and the disabilities that follow.
