New therapeutic strategies are needed to protect neonates, especially premature
newborns, against brain injury and associated neurobehavioral deficits. The role
of pro-inflammatory cytokines, especially IL-1?, in the pathophysiological
pathway leading to neonatal brain damage is increasingly recognized and
represents an attractive therapeutic target. We investigated the therapeutic
potential of postnatal systemic administration of the interleukin (IL)-1 receptor
antagonist (IL-1Ra) in an animal model of perinatal brain injury using the
insults most common to human neonates, i.e. prenatal exposure to inflammation
and/or postnatal hypoxia-ischaemia (HI). We found that postnatal administration
of IL-1Ra preserved motor function and exploratory behavior after either prenatal
exposure to inflammatory agent lipopolysaccharide (LPS) or postnatal HI insult.
The deleterious effect of combined prenatal LPS and postnatal HI on brain
development was also alleviated by administration of IL-1Ra, as seen by the
protected neural stem cell population, prevention of myelin loss in the internal
capsule, decreased gliosis, and decreased neurobehavioral impairment. This study
showed the distinct pattern of functional deficits induced by prenatal
inflammation as compared to postnatal HI and the therapeutic potential of IL-1Ra
administration against neonatal brain injury. Furthermore, our results highlight
the potential for postnatal treatment of prenatal inflammatory stressors.
