Project description:Vaccination in pregnancy is an effective tool to protect both the mother and infant. Vaccines against tetanus, pertussis and influenza are recommended for use in pregnancy and new vaccines with specific indications for pregnancy are in the clinical trials pipeline. However our understanding of the immune response to vaccination in pregnancy is incomplete. We compared the effect of pregnancy on early (24 hours) transcriptional responses to vaccination. Pregnant mice and women were immunised with Boostrix-IPV, a vaccine containing pertussis antigens.

Project description:Chronic hypertension during pregnancy affects both mother and infant but its pathological mechanisms are unclear. Due to ethical limitations human data is available in term tissue only- so deeper understanding of the vascular changes during early pregnancy are unknown. This study utilises a known rat model of chronic hypertension to study changes in gene expression at an early gestational time point. After 6 days of pregnancy animals were sacrificed and main uterine arteries harvested for RNA-Seq (or age-matched virgin rats as controls).

Project description:Influenza immunization during pregnancy provides protection to the mother and the infant. Studies in adults and children with inactivated influenza vaccine (IIV) have identified changes in immune gene expression that correlated with antibody responses. We studied changes in transcriptional profiles induced by IIV in pregnant women and to identify correlates of antibody responses.

Project description:We report that the DNA methylation profile of a child’s neonatal whole blood can be significantly influenced by his or her mother’s neonatal blood lead levels (BLL). We recruited 35 mother-infant pairs in Detroit and measured the whole blood lead (Pb) levels and DNA methylation levels at over 450,000 loci from current blood and neonatal blood from both the mother and the child. We found that mothers with high neonatal BLL correlate with altered DNA methylation at 564 loci in their children’s neonatal blood. Our results suggest that Pb exposure during pregnancy affects the DNA methylation status of the fetal germ cells, which leads to altered DNA methylation in grandchildren’s neonatal dried blood spots. This is the first demonstration that an environmental exposure in pregnant mothers can have an epigenetic effect on the DNA methylation pattern in the grandchildren. For the study, we selected 35 dried blood spots (DBS) collected from mother-infant pairs from Health Fairs ran in three Detroit communities, because they have a high prevalence (8-11%) of high BLL in children. The sample set consisted of 25 male children and 18 female children. We also collected the neonatal DBS and mother neonatal DBS for these mother-infant pairs from the Michigan Neonatal Biobank. Then we measured a blood lead levels in dried blood spots using using atomic absorbtion spectrophotometry. Finally we measured the DNA methylation levels using human methylation 450K array from Illumina. Then we normalized the data for technical biases and tried to infer the the locus specific DNA methylation changes due to Pb exposure which was carried over from the grandmothers to the grandchildren by the Pb –exposed fetal germ cells of the mother using statistical model proposed by Sofer et al, 2012.

Project description:Human milk is the truest form of personalized nutrition, supporting dynamic needs of the infant with important nutritional and bioactive constituents that change throughout lactation. Additionally, human milk is individual specific and is unique for each mother-infant dyad. Proteins and endogenous peptides are 2 key classes of major human milk components making up the proteome, each with unique and synergistic functionality, working to provide protection for the healthy development of infants. Our objective was to comprehensively characterize and quantify the human milk proteome for varying early life challenges. We assessed in-depth individual variations of the human milk proteome across lactation, by mass spectrometry. Finding that the human milk proteome showed continuous and gradual changes over lactation, and that inflammatory events correlated with a strong and rapid change in the composition of human milk proteins and peptides. Personalized human milk profiling resulted in the systematic annotation of the milk proteome, and elucidated how early onset inflammatory events can lead to infant immune training from human milk.

Project description:Influenza virus transmission between mothers and nursing-infants has not been investigated although mothers and infants often develop severe disease. Ferrets are considered the most appropriate model for influenza studies. We investigated influenza transmission in infant and nursing-mother ferrets. Influenza infected infants transmitted virus to mother mammary glands leading to live virus excretion in milk and influenza virus positive mammary gland epithelial cells. Global gene expression analysis showed down-regulation of milk production and induction of breast involution and oncogenesis pathways. Our results provide insight into influenza transmission between mothers and infants which may impact fields of infectious disease, maternal/infant health and neoplasm etiology. Total RNA was obtained from nursing mother ferret mammary glands at days 3/4 and 6/7 post-intranasal kit infection with 10^5 EID50 A/California/07/2009 (H1N1). Total RNA was also collected from uninfected control nursing mother mammary gland tissues (n = 3). Changes in gene expression relative to uninfected tissue controls were then investigated.

Project description:LC-MS/MS analysis formula was performed for sera from 22 mother-infant dyads with HLA-conferred susceptibility to type 1 diabetes that were weaned to either an extensively hydrolyzed or regular infant milk. The samples included three samples from each mother (at the beginning of third trimester, at the time of delivery and 3 months postpartum) and five samples from each child (cord blood, 3, 6, 9 and 12 months). Targeted proteomics was used to validate differences observed between the feeding groups.Correlations in protein intensities within the dyads were detected together with perinatal and age-related changes.
