Impact of chorioamnionitis exposure on neonatal monocyte H3K4me3 patterning

ABSTRACT: We sought to determine the impact of chorioamnionitis exposure on the neonatal monocyte H3K4me3 histone modification landscape over the course of fetal and neonatal immune system development using ChIP-seq. H3K4me3 ChIP-seq was performed on umbilical cord blood purified CD14+ monocytes from healthy and chorioamnionitis-exposed extremely preterm neonates (under 30 weeks gestation), late preterm neonates (30-36 weeks gestation), and term neonates (37+ weeks gestation).

Plasma proteomic analysis to identify potential biomarkers of histologic chorioamnionitis in women with preterm premature rupture of membranes

Project description:Preterm premature rupture of membranes (PPROM), which precedes approximately 30–40% of preterm births, is the main cause of neonatal morbidity, mortality, and long-term sequelae. In particular, almost half of all PPRPM cases are frequently complicated by subclinical acute inflammation in the placenta and fetal tissue, commonly named as acute histologic chorioamnionitis [HCA]. Increasing evidences suggest that HCA carries additional risks to both the pregnant women and their fetuses, including greater risk of imminent preterm birth, as well as sepsis, neurologic morbidity, and mortality in neonates. More accurate and early prenatal predictive markers (especially noninvasive ones) are urgently needed for identifying subclinical HCA in the context of PPROM.To identify potential biomarkers in the plasma that could predict histologic chorioamnionitis (HCA) in women with preterm premature rupture of membranes (PPROM), using shotgun and targeted proteomic analyses.

Effect of chorioamnionitis exposure on neonatal monocyte transcription

Project description:We sought to determine the impact of chorioamnionitis exposure on term neonatal monocyte transcription. RNA-seq was performed on term healthy and chorioamnionitis-exposed umbilical cord blood purified CD14+ monocytes under unstimulated and LPS stimulated conditions.

Data in support of Prenatal intra-amniotic lipopolysaccharide induces neonatal renal immune activation after preterm birth

Project description:Preterm birth is often predisposed by chorioamnionitis (CA) and CA affects the fetal gut and lungs via intra-amniotic (IA) inflammation, thus accentuating the proinflammatory effects of preterm birth. It is not known if IA inflammation also affects other perfusion-sensitive organs (e.g., kidneys) before and after preterm birth. Using preterm pigs as model for preterm infants, we hypothesized that CA induces fetal and neonatal renal dysfunctions that can intially be detected via plasma proteome, partly explaining the frequent renal dysfunction in preterm infants. Fetal pigs (88% gestation) were given an IA dose of lipopolysaccharide (LPS, 1 mg/kg, n=28), delivered preterm by cesarean section three days later, and compared with controls (CON, n=26) at birth and postnatal day five. Plasma proteome and protein markers of inflammatory pathways were evaluated.

DNA Methylation Profile in Human Cord Blood Mononuclear Leukocytes from Term Neonates: Effects of Histological Chorioamnionitis

Project description:Genome wide DNA methylation profiling of human cord blood mononuclear leokocytes (CBML) from neonates exposed to histological chorioamnionitis (HCA) compared to healthy neonates. The Infinium HumanMethylationEPIC BeadChip array was used to obtain DNA methylation profiles across 866,836 CpGs in five HCA and five control samples.

Histological Chorioamnionitis Induces Differential Gene Expression in Human Cord Blood Mononuclear Leukocytes from Term Neonates

Project description:Human transcriptome array analysis of human cord blood mononuclear leokocytes from neonates exposed to histological chorioamnionitis and compared with healthy neonates Histological chorioamnionitis (HCA) is an infection of fetal membranes and complicates 5.2% to 28.5% of all live births. Exposure to HCA may have long-term consequences including an increased risk for allergic disorders and asthma later in childhood, the mechanism(s) of which are still not yet well understood. Our objective was to determine the mRNA transcriptome of cord blood mononuclear leukocytes from term neonates and identify key genes and pathways involved in HCA. We found several key genes differentially expressed with exposure to HCA. These transcriptomes included novel genes and pathways associated with exposure to HCA. The differential gene expression included the key genes regulating inflammatory, immune, respiratory and neurological pathways, which may contribute to disorders in those pathways in neonates exposed to HCA.

Fetal lung maturation induced by chorioamnionitis and its interaction with antenatal corticosteroids in rhesus macaque fetuses

Project description:Purpose: Our goal was to evaluate the pathways through which chorioamnionitis induces fetal lung maturation and how it interacts with a low-dose treatment with antenatal corticosteroids to further enhance fetal lung maturation. Methods: We treated pregnant rhesus macaque at 132 days (80% gestation) with intre-amniotic bacterla lipopolissacharide to model chorioamnionitis or a low-dose antenatal corticosteroids treatment with betamethasone-acetate (Beta-Ac 0.125mg/kg) or both treatments. Fetuses were delivered by c-section after 5 days and RNA-sequencing of whole lung tissue was performed. Another group of fetuses exposed to LPS was delivered 16h after treatment. Preterm controls were delivered at 132 days and term controls were delivered at 155 days and received no intervention. Results: Treatment with Beta-Ac in the setting of chorioamnionitis improves lung compliance and increases surfactant production relative to either treatment alone. RNA sequencing shows that these changes are mediated by suppression of proliferation and induction of mesenchymal cellular death. The combined exposure results in a mature-like transcriptomic profile with inhibition of extracellular matrix development by suppression of collagen genes and regulators of lung development. ACS and inflammation also suppressed signature genes associated with proliferative mesenchymal progenitors similar to the term lung. Conclusion: Treatment with ACS in the setting of inflammation may result in early respiratory advantage to preterm infants, but this advantage may come at a cost of abnormal extracellular matrix development which may be associated with increased risk of chronic lung disease.
