Article
Full-text available
Chorioamnionitis and intrauterine growth retardation (IUGR) are risk factors for cerebral palsy (CP). Common bacteria isolated in chorioamnionitis include group B Streptococcus (GBS) serotypes Ia and III. Little is known about the impact of placental inflammation induced by different bacteria, including different GBS strains. We aimed to test the i...
Article
Full-text available
Group B Streptococcus (GBS) is one the most common bacterium responsible of maternal infections during pregnancy. Offspring in utero-exposed to GBS-induced placental inflammation displayed sex-specific forebrain injuries. Sex differences have been reported in several neuropsychiatric disorders. Hence, we hypothesized that female rats in utero-expos...
Chapter
It is known that gestational and/or perinatal inflammation combined or not with hypoxia-ischemia (HI) is a risk factor for brain injuries, but the mechanisms underlying are still unclear. This chapter discusses about animal models mimicking those conditions, allowing scientists to uncover mechanisms involved and to study the adverse effects on the...
Article
Full-text available
Inflammation due to remote pathogen exposure combined to hypoxia/ischemia (HI) is one of the most common causes of neonatal encephalopathy affecting at-term or near-term human newborn, which will consequently develop cerebral palsy. Within term-equivalent rat brains exposed to systemic lipopolysaccharide (LPS) plus HI, it was previously showed that...
Article
Full-text available
Infection-inflammation combined with hypoxia-ischemia (HI) is the most prevalent pathological scenario involved in perinatal brain damage leading to life-long neurological disabilities. Following lipopolysaccharide (LPS) and/or HI aggression, different patterns of inflammatory responses have been uncovered according to the brain differentiation sta...
Article
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-1β, in the pathophysiological pathway leading to neonatal brain damage is increasingly recognized and represents an attractive therapeutic targe...
Article
Full-text available
Preterm and term newborns are at high risk of brain damage as well as subsequent cerebral palsy and learning disabilities. Indeed, hypoxia-ischemia (HI), pathogen exposures, and associated intracerebral increase of pro-inflammatory cytokines have all been linked to perinatal brain damage. However, the developmental effects of potential variations o...
Article
Inflammatory molecules are promptly upregulated in the fetal environment and postnatally in brain-damaged subjects. Intrauterine infections and inflammation are often associated with asphyxia. This double-hit effect by combined infection or inflammation and hypoxia is therefore a frequent concomitant in neonatal brain damage. Animal models combinin...
