- PROBLEM: How maternal allergy affects the systemic and local immunological environment during pregnancy and the immune development of the offspring is unclear.METHOD OF STUDY: Expression of 40 genes was quantified by PCR arrays in placenta, peripheral blood mononuclear cells (PBMC), and cord blood mononuclear cells (CBMC) from 7 allergic and 12 non-allergic women and their offspring.RESULTS: Placental gene expression was dominated by a Th2-/anti-inflammatory profile, irrespectively of maternal allergy, as compared to gene expression in PBMC. p35 expression in placenta correlated with fetal Tbx21 (ρ = -0.88, P < 0.001) and IL-5 expression in PBMC with fetal galectin1 (ρ = 0.91, P < 0.001). Increased expression of Th2-associated CCL22 in CBMC preceded allergy development.CONCLUSIONS: Gene expression locally and systemically during pregnancy was partly associated with the offspring's gene expression, possibly indicating that the immunological milieu is important for fetal immune development. Maternal allergy was not associated with an enhanced Th2 immunity in placenta or PBMC, while a marked prenatal Th2 skewing, shown as increased CCL22 mRNA expression, might contribute to postnatal allergy development.

- Problem The boar, as human, sequentially ejaculates sperm-rich and sperm-poor fractions. Seminal plasma (SP) spermadhesins (PSP-I/PSP-II) induce a primary endometrial inflammatory response in female sows, similar to that elicited by semen deposition in other species, including human. However, the SP is also known to mitigate such response, making it transient to allow for embryo entry to a cleansed endometrium. Although cytokine involvement has been claimed, the exploration of cytokines in different SP fractions is scarce. This study determines Th1, Th2, Th17 and Th3 cytokine profiles in specific ejaculate SP fractions from boars of proven fertility. Methods SP samples from the sperm-rich fraction (SRF) and the sperm-poor post-SRF fraction (post-SRF) of manually collected ejaculates from eight boars (four ejaculates per boar) were analysed by commercial multiplex bead assay kits (Milliplex MAP, Millipore, USA) for interferon-gamma, interferon gamma-induced protein 10, macrophage-derived chemokine, growth-regulated oncogene, granulocyte-macrophage colony-stimulating factor, monocyte chemo-attractant protein-1, interleukins (IL)-6, IL-8, IL-10, IL-15, IL-17 and transforming growth factor (TGF)-beta 1-beta 3. Results Cytokine concentrations differed between the ejaculate fractions among boars, being highest in the post-SRF. Conclusion Boar SP is rich in Th1, Th2, Th17 and Th3 cytokines, with lowest concentrations in the sperm-peak-containing fraction, indicating its main immune influence might reside in the larger, protein-rich sperm-poor post-SRF.

- Problem A deficiency in regulatory T (Treg) cells causing reduced immune regulatory capacity has been proposed in preeclampsia. Objective Utilizing recent advances in flow cytometry phenotyping, we aimed to assess whether a deficiency of Treg subpopulations occurs in preeclampsia. Method of study Six-color flow cytometry was used for Treg phenotyping in 18 preeclamptic women (one early-onset, one severe and 16 both), 20 women with normal pregnancy, and 20 non-pregnant controls. Results No differences were found in major Treg populations including CD127(low)CD25(+)/CD127(ow)FOXP3(+), resting (FOXP3(dim)CD45RA(+)), and activated (FOXP3(bright)CD45RA(-)) Treg cells, whereas preeclamptic women showed increased CTLA-4(+) and CCR4(+) proportions within resting/activated Treg populations. Corticosteroid treatment prior to blood sampling (n = 10) affected the distribution of Treg populations. Conclusions Although we found no major alterations in circulating Treg frequencies, differences in CTLA-4(+) and CCR4(+) frequencies suggest a migratory defect of Treg cells in preeclampsia. Corticosteroid treatment should be taken into account when evaluating Treg cells.

- ProblemChronic pelvic pain (CPP) causes compromised the quality of life in women with endometriosis and is often attributed to local inflammation and ingrowth of nerve fibers. In this pilot study, we aimed to investigate whether the inflammation‐related vasoactive intestinal peptide (VIP) and interleukin (IL)‐6 were increased in affected patients.Method of studyEndometrial and endometriotic tissue biopsy specimens, and serum and peritoneal fluid (PF) samples, were obtained from 85 endometriosis patients and 53 controls. VIP and IL‐6 analysis and measurement of microvessel density in tissue were performed using immunohistochemistry, Western blotting, RT‐qPCR, and ELISA.ResultsCompared with controls, VIP transcript and protein levels were increased in endometrium from endometriosis patients and further elevated in patients with CPP. In addition, microvessel density, a measurement of angiogenic activity, was increased in the endometrium and in endometriosis lesions in the same subset of patients. Serum and PF levels of VIP and IL‐6 were higher in women with endometriosis and CPP compared with endometriosis patients who reported no chronic pain.ConclusionVasoactive intestinal peptide is upregulated in endometriosis patients reporting chronic pain. Increased microvessel density in tissue and peritoneal fluid concentrations of IL‐6 indicate an elevated inflammation in the pelvic microenvironment of these patients.

- Preeclampsia is a pregnancy-related disease afflicting 3-7% of pregnancies worldwide and leads to maternal and infant morbidity and mortality. The disease is of placental origin and is commonly described as a disease of two stages. A variety of preeclampsia animal models have been proposed, but all of them have limitations in fully recapitulating the human disease. Based on the research question at hand, different or multiple models might be suitable. Multiple animal models in combination with in vitro or ex vivo studies on human placenta together offer a synergistic platform to further our understanding of the etiology of preeclampsia and potential therapeutic interventions. The described animal models of preeclampsia divide into four categories (i) spontaneous, (ii) surgically induced, (iii) pharmacologically/substance induced, and (iv) transgenic. This review aims at providing an inventory of novel models addressing etiology of the disease and or therapeutic/intervention opportunities.
