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: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:The iTRAQ analysis combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was performed to separate differentially expressed placental proteins from 4 pregnant women with ICP and 4 healthy pregnant women.
Project description:Breastfeeding protects against mucosal infections in infants. The underlying mechanisms through which immunity develops in human milk following maternal infection with mucosal pathogens are not well understood. We simulate mucosal influenza infection through live attenuated influenza vaccination (LAIV) and compared milk and blood immune responses to inactivated influenza vaccination (IIV). Transcriptomic analysis was performed on RNA extracted from human milk and whole blood. Differentially expressed genes (DEGs) and gene set enrichment analysis (GSEA) on days 1 and 7 post-vaccination were compared to pre-vaccination.
Project description:Longitudinal Gene expression profiling of whole blood from critically ill influenza and bacterial pneumonia patients. In addition before vs 7 days post influenza vaccination volunteer samples are assayed. 3 groups of samples. First is bacterial pneumonia patients with 6 subjects sampled for up to 5 days. Second group is severe influenza infection with 4 subjects sampled for up to 5 days. Third group is influenza vaccination with 18 subjects sampled before and 7 days post vaccination.
Project description:Polycystic ovary syndrome (PCOS) is the most common endocrinological disorder of fertile-aged women. PCOS has been associated with adverse pregnancy outcomes and abnormalities of the placenta. By taking a quantitative label-free quantitative proteomics approach we set out to investigate if changes in the plasma proteome of pregnant women with PCOS could elucidate the mechanisms behind the pathologies observed in PCOS pregnancies. We have performed label-free quantitative proteomics on plasma samples from pregnant women with PCOS at term (n=14) and plasma samples from pregnant control women (n = 23) matched for age, gestational length and BMI. The samples are derived from BASIC pregnancy cohort from Uppsala, Sweden. A total of 169 proteins with two or more unique peptides were identified.
