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.

Abstract [en]

Background: The influence of maternal allergy on the development of immune responses and allergy in the offspring is not understood.

Objective: To investigate (i) if maternal allergy influences the gene expression locally in placenta, systemically in peripheral blood mononuclear cells (PBMC) and fetally in cord blood mononuclear cells (CBMC), (ii) if the gene expression in the placenta and PBMC influences the gene expression in CBMC and (iii) how the gene expression at birth relates to allergy development during  childhood.

Methods: A real-time PCR array was used to quantify forty immune regulatory genes in placenta, PBMC (gestational week 39) and in CBMC from 7 allergic and 12 non-allergic women and their offspring. Furthermore, quantitative real-time PCR was used to measure mRNA expression of Tbx21, GATA-3, Foxp3, RORC and CCL22 in CBMC, selected based on present PCR array results and previous protein findings in cord blood, in 13 children who developed and 11 children who did not develop allergy during childhood.

Results: The gene expression profile in the placenta revealed a T-helper (Th) 2-/anti-inflammatory environment as compared with gene expression systemically, in PBMC. Maternal allergy was associated with increased expression of p35 in PBMC and CBMC and p40 in placenta. Placental p35 expression correlated with fetal Tbx21 expression (Rho=-0.88, p<0.001) and maternal IL-5 expression in PBMC with fetal Galectin-1 (Rho=0.91, p<0.001) expression. Allergy development in the children was preceded by high mRNA expression of the Th2-associated chemokine CCL22 at birth.

Conclusion and clinical relevance: Gene expression locally and systemically during pregnancy influenced the offspring’s gene expression at birth, indicating an interplay between maternal and fetal immunity. Children developing allergy during childhood had an increased expression of the Th2-associated chemokine CCL22 at birth, indicating a Th2 skewing before disease onset. Maternal allergy was not associated with a Th2-dominance in placenta, PBMC or CBMC.

Abstract [en]

Background: Pregnancy and allergic disease have both been postulated as T-helper 2 (Th2) phenomena. Thus, the increased propensity of allergic mothers to mount Th2-responses might generate favourable effects on the maintenance of pregnancy, but might also be unfavorable, as fetal exposure to a strong Th2 environment could influence the immune development in the offspring to a Th2-like phenotype, favouring IgE production and possibly allergy development later in life. The influence of the intrauterine environment on the immunity and allergy development in the offspring needs to be further investigated.

Aim: The aim of this thesis was to explore the Th1/Th2 balance in allergic and non-allergic women during pregnancy and its influence on the shaping of the Th1/Th2 profile in the neonate and the development of allergic diseases in the offspring.

Material and methods: The study group included 20 women with and 36 women without allergic symptoms followed during pregnancy (gestational week 10-12, 15-16, 25, 35, 39) and 2 and 12 months postpartum, and their children followed from birth to 6 years of age. The circulating Th1-like chemokines CXCL9, CXCL10, CXCL11, Th2-like chemokines CCL17, CCL18 and CCL22, and the allergen-induced secretion of interleukin-4 (IL-4), IL-5, IL-10, IL-13, Interferon-γ (IFN-γ), CXCL10 and CCL17 were measured by Luminex and ELISA. The allergen-specific and total IgE levels were quantified using ImmunoCAP Technology. mRNA expression of Th1-, Th2-, Treg- and Th17-associated genes were measured by PCR arrays and real-time PCR.

Results: We found that sensitised women with allergic symptoms had increased total IgE levels and birch- and cat-induced IL-5, IL-13 and CCL17 responses during pregnancy as compared with postpartum. The non-sensitised women without allergic symptoms had elevated cat-induced IL-5 and IL-13 responses and lower birch- and cat-induced IFN-γ during pregnancy, but similar IgE levels as compared with postpartum.

Maternal total IgE levels during and after pregnancy correlated with cord blood (CB) IgE and CCL22 levels (regardless of maternal allergy status). Circulating CXCL11, CCL18 and CCL22 levels during pregnancy and postpartum correlated with the corresponding chemokine levels in the offspring at various time points during childhood. Maternal IL-5 expression in peripheral blood mononuclear cells (PBMC) was associated with neonatal Galectin-1, and placental p35 expression was negatively associated with neonatal Tbx21 expression. Increased mRNA expression of CCL22 in cord blood mononuclear cells (CBMC), and increased CCL17 and CCL22 levels in CB were observed in children later developing allergic symptoms and sensitisation as compared with children who did not. Development of allergic symptoms and sensitisation were associated with increased total IgE, CCL17, CCL18 and CCL22 levels during childhood.

Conclusions: Maternal allergy was associated with a pronounced Th2 deviation during pregnancy, shown as increased total IgE levels and birch- and cat-induced IL-5, IL-13 and CCL17 responses during pregnancy, possibly exposing their fetuses to a particular strong Th2 environment during gestation.

Correlations were shown between the maternal immunity during pregnancy and the offspring’s immunity at birth and later during childhood, indicating an interplay between the maternal and fetal immunity.

Allergy development during the first 6 years of life was associated with a marked Th2 deviation at birth and a delayed down-regulation of this Th2-skewed immunity during childhood.

Abstract [en]

The immunological milieu in the placenta may be crucial for priming the developing foetal immune system. Early imbalances may promote the establishment of immune-mediated diseases in later life, including allergies. The initial exposure to allergens seems to occur in utero, but little is known about allergen-induced placental cytokine and chemokine release. The release of several cytokines and chemokines from placenta tissue after exposure to mast cell degranulator compound 48/80 or apple allergen in placentas from allergic and healthy mothers was to be analysed. Four placentas from women with apple allergy and three controls were applied in a placental perfusion model with two separate cotyledons simultaneously perfused with and without apple allergen (Mal d 1). Two control placentas were perfused with compound 48/80. In outflow, histamine was quantified spectrophotofluorometrically, IL-2, IL-4, IL-6, IL-10, TNF and IFN-gamma by a cytometric multiplex bead array and IL-13 and CXCL10, CXCL11, CCL17 and CCL22 with an in-house multiplex Luminex assay. Compound 48/80 induced a rapid release of histamine, CXCL10, CXCL11, CCL17 and CCL22, but not of the other factors. Apple allergen induced a time-dependent release of IL-6 and TNF, but not of histamine, in placentas of women with apple allergy compared with the unstimulated cotyledon. CCL17 levels were slightly increased after allergen stimulation in control placentas. Allergens can induce placental cytokines and chemokines distinctly in allergic and healthy mothers. These mediators may affect the prenatal development of the immune system and modify the risk of diseases related to immune disorders in childhood such as allergies.

Abstract [en]

Background: The influence of the intra-uterine environment on the immunity and allergy development in the offspring is unclear. We aimed to investigate (i) whether the pregnancy magnifies the Th2 immunity in allergic and non-allergic women, (ii) whether the maternal chemokine levels during pregnancy influenced the offspring’s chemokine levels during childhood and (iii) the relationship between circulating Th1/Th2-associated chemokines and allergy in mothers and children.

Methods: The Th1-associated chemokines CXCL9, CXCL10, CXCL11, and the Th2- associated chemokines CCL17, CCL18 and CCL22 were quantified by Luminex and ELISA in 20 women with and 36 women without allergic symptoms at gestational week (gw) 10–12, 15–16, 25, 35, 39 and 2 and 12 months post-partum and in their children at birth, 6, 12, 24 months and 6 yr of age. Total IgE levels were measured using ImmunoCAP Technology.

Results: The levels of the Th2-like chemokines were not magnified by pregnancy. Instead decreased levels were shown during pregnancy (irrespectively of maternal allergy status) as compared to post-partum. In the whole group, the Th1-like chemokine levels were higher at gw 39 than during the first and second trimester and post-partum. Maternal CXCL11, CCL18 and CCL22 levels during and after pregnancy correlated with the corresponding chemokines in the offspring during childhood. Increased CCL22 and decreased CXCL10 levels in the children were associated with sensitisation and increased CCL17 levels with allergic symptoms during childhood. Maternal chemokine levels were not associated with maternal allergic disease.

Conclusions: Allergic symptoms and sensitisation were associated with decreased Th1-and increased Th2-associated chemokine levels during childhood, indicating a Th2 shift in the allergic children, possibly influenced by the maternal immunity during pregnancy.

Abstract [en]

Normal pregnancy and allergy are both characterized by a T helper (Th) 2 deviation. In the current study, we hypothesized that paternal antigen-induced cytokine responses during pregnancy would be deviated toward Th2 and an anti-inflammatory profile, and that the Th2 deviation would be more pronounced in allergic pregnant women. Blood samples were collected longitudinally on three occasions during pregnancy and two occasions post partum (pp). Of the 86 women initially included, 54 women had a normal pregnancy and completed the sampling procedures. Twelve women fulfilled the criteria for allergy (allergic symptoms and circulating immunoglobulin [Ig] E antibodies to inhalant allergens) and 20 were non-allergic (nonsensitized without symptoms). The levels of Th1- and Th2-associated cytokines and chemokines, the Th17 cytokine IL-17 and the anti-inflammatory cytokine IL-10 of the groups were compared. Paternal antigen-induced IL-4 and IL-10 responses increased between the first and the third trimester. Allergy was associated with decreased paternal antigen-induced IFN-γ and CXCL10 secretion in the nonpregnant state (one year pp) and also decreased IFN-γ/IL-4 and IFN-γ/IL-13 ratios during pregnancy. We also observed a decreased paternal antigen-induced IL-10 response in allergic compared with non-allergic women during pregnancy, along with a decreased IL-10/IL-13 ratio. In conclusion, our findings support the hypothesis of lower Th1 responses toward paternal antigens in allergic than in non-allergic women, but also indicate that allergy is associated with a lower capacity to induce anti-inflammatory IL-10 responses after paternal antigen stimulation during pregnancy.

Abstract [en]

Ro52 (TRIM21) is an E3 ligase of the tripartite motif family that negatively regulates proinflammatory cytokine production by ubiquitinating transcription factors of the interferon regulatory factor family. Autoantibodies to Ro52 are present in patients with lupus and Sjögren's syndrome, but it is not known if these autoantibodies affect the function of Ro52. To address this question, the requirements for Ro52 E3 ligase activity were first analyzed in detail. Scanning a panel of E2 ubiquitin-conjugating enzymes, we found that UBE2D1–4 and UBE2E1–2 supported the E3 ligase activity of Ro52 and that the E3 ligase activity of Ro52 was dependent on its RING domain. We also found that the N-terminal extensions in the class III E2 enzymes affected their interaction with Ro52. Although the N-terminal extension in UBE2E3 made this E2 enzyme unable to function together with Ro52, the N-terminal extensions in UBE2E1 and UBE2E2 allowed for a functional interaction with Ro52. Anti-Ro52-positive patient sera and affinity-purified anti-RING domain autoantibodies inhibited the E3 activity of Ro52 in ubiquitination assays. Using NMR, limited proteolysis, ELISA, and Ro52 mutants, we mapped the interactions between Ro52, UBE2E1, and anti-Ro52 autoantibodies. We found that anti-Ro52 autoantibodies inhibited the E3 ligase activity of Ro52 by sterically blocking the E2/E3 interaction between Ro52 and UBE2E1. Our data suggest that anti-Ro52 autoantibodies binding the RING domain of Ro52 may be actively involved in the pathogenesis of rheumatic autoimmune disease by inhibiting Ro52-mediated ubiquitination.

Abstract [en]

Exposure to a strong T-helper 2 (Th2)-like environment during fetal development may promote allergy development. Increased cord blood (CB) levels of the Th2-associated chemokine CCL22 were associated with allergy development during the first 2 y of life. The aim of the present study was to determine whether CB Th1- and Th2-associated chemokine levels are associated with allergy development during the first 6 y of life, allowing assessment of respiratory allergic symptoms usually developing in this period. The CB levels of cytokines, chemokines, and total IgE were determined in 56 children of 20 women with allergic symptoms and 36 women without allergic symptoms. Total IgE and allergen-specific IgE antibody levels were quantified at 6, 12, 24 mo, and 6 y of age. Increased CB CCL22 levels were associated with development of allergic sensitization and asthma and increased CCL17 levels with development of allergic symptoms, including asthma. Sensitized children with allergic symptoms showed higher CB CCL17 and CCL22 levels and higher ratios between these Th2-associated chemokines and the Th1-associated chemokine CXCL10 than nonsensitized children without allergic symptoms. A pronounced Th2 deviation at birth, reflected by increased CB CCL17 and CCL22 levels, and increased CCL22/CXCL10 and CCL17/CXCL10 ratios might promote allergy development later in life.

Abstract [en]

Background: Analyses of circulating chemokines offer novel tools to investigate the Th1/Th2 imbalance in allergic disease in vivo and explore the influence of pre- and postnatal factors in infancy.

Objective: To relate circulating Th1- and Th2-associated chemokines to the development of allergic disease, pre- and postnatal factors and probiotic supplementation in infancy.

Methods: Circulating levels of Th1-associated CXC-chemokine ligand (CXCL)9, CXCL10 and CXCL11 and Th2-associated CC-chemokine ligand (CCL)17, CCL18 and CCL22 were assessed with Luminex and ELISA at birth (n=109), 6 (n=104), 12 (n=116) and 24 months (n=123) in 179 infants completing a double-blind placebo-controlled allergy prevention trial with Lactobacillus reuteri during the last month of gestation and through the first year of life. The infants were followed regarding development of allergic disease and sensitization until two years of age.

Results: The Th2-associated chemokines were as highest at birth and then decreased, whereas the Th1-associated chemokines increased with age. Low Th1- and high Th2-associated chemokine levels were observed in children developing allergic disease. Sensitization was preceded by elevated CCL22 and reduced CXCL11 levels. High Th2-associated chemokine46 levels were associated with increased birth length and weight and long duration of breastfeeding, and high Th1-associated chemokine levels with day-care attendance. Presence of L. reuteri in stool the first week of life was associated with low CCL17 and CCL22 and high CXCL11 levels at 6 months.

Conclusion: Allergic disease in infancy was associated with low circulating Th1- and high Th2-associated chemokine levels during the first year of life. The chemokine levels were affected by both pre and –postnatal factors.
