Integrating Statistical Evidence and Legal Theory to Challenge the Selection of Grand and Petit Jurors

The increasing allergy prevalence in affluent countries may be caused by reduced microbial stimulation and a decreased dietary ω-3/ω-6 long-chain polyunsaturated fatty acid (LCPUFA) ratio, resulting in an abnormal postnatal immune maturation. The timing of allergy-preventive probiotic and ω-3 LCPUFA interventions is critical, as early-life events occurring during critical windows of immune vulnerability can have long-term impact on immune development. The maternal dietary and microbial environment during pregnancy may programme the immune development of the child. Prenatal environmental exposures may alter gene expression via epigenetic mechanisms, aiming to induce physiological adaptations to the anticipated postnatal environment, but potentially also increasing disease susceptibility in the offspring if exposures are mismatched. Although the importance of fetal programming mostly has been studied in cardiovascular and metabolic disease, this hypothesis is also very attractive in the context of environmentally influenced immune-mediated diseases. This review focuses on how prenatal, perinatal or postnatal ω-3 LCPUFA interventions regulate childhood immune and allergy development, and if synergistic effects may be obtained by simultaneous probiotic supplementation. We propose that combined pre- and postnatal preventive measures may be most efficacious. Increasing knowledge on the immunomodulatory effects of prenatal, perinatal and postnatal interventions will help to direct future strategies to combat the allergy epidemic.Funding Agencies|Swedish Research Council||Ekhaga Foundation||Research Council for the South-East Sweden||Swedish Asthma and Allergy Association||Olle Engkvist Foundation||Vardal Foundation - for Health Care Sciences and Allergy Research||</p

Ashcroft v. Iqbal: The Question of a Heightened Standard of Pleading in Qualified Immunity Cases

Background We have previously shown that Lactobacillus reuteri supplementation from pregnancy week 36 and to the infant through the first year of life decreased the prevalence of IgE-associated eczema at 2 years. The underlying immunological mechanisms are unknown, however. Objective To investigate the immunomodulatory effect of probiotic supplementation on allergen- and mitogen-induced immune responses in children until 2 years of age. Methods Blood mononuclear cells were collected at birth, 6, 12 and 24 months from 61 children (29 probiotic and 32 placebo treated) and cultured with ovalbumin, birch and cat extract and Phytohaemagglutinin (PHA). Cytokine and chemokine secretion was determined using an in-house multiplexed Luminex assay and ELISA. Real-time PCR was performed to investigate the Ebi3, Foxp3, GATA-3 and T-bet mRNA expression. Results Probiotic treatment was associated with low cat-induced Th2-like responses at 6 months (IL-5, P = 0.01, and IL-13, P = 0.009), with a similar trend for IL-5 at 12 months (P = 0.09). Cat-induced IFN-γ responses were also lower after probiotic than after placebo treatment at 24 months (P = 0.007), with similar findings for the anti-inflammatory IL-10 at birth (P = 0.001) and at 12 months (P = 0.009). At 24 months, Th2-associated CCL22 levels were lower in the probiotic than in the placebo group after birch stimulation (P = 0.02), with a similar trend after ovalbumin stimulation (P = 0.07). Lower CCL22 levels were recorded at 12 and 24 months (P = 0.03 and P = 0.01) after PHA stimulation. Conclusion and Clinical Relevance Lactobacillus reuteri supplementation decreases allergen responsiveness and may enhance immunoregulatory capacity during infancy. L. reuteri supplementation from week 36 and during the first year of life significantly decreases IgE-associated eczema and lowers allergen and mitogen responsiveness.Funding Agencies|Swedish Research Council|K2011-56X-21854-01-06|Ekhaga Foundation||Olle Engkvist Foundation||Heart and Lung foundation||Research Council for the South-East Sweden|F2000-106|Swedish Asthma and Allergy Association||Cancer and Allergy Association||BioGaia AB, Stockholm, Sweden||University Hospital of Linkoping, Sweden||</p

Reconsidering Res Judicata: A Comparative Perspective

We aimed to prospectively investigate the paternal antigen-induced cytokine secretion by peripheral blood mononuclear cells (PBMCs) in response to hormone treatment in women undergoing in vitro fertilisation (IVF) and to examine the predictive value of the cytokine secretion profile in the outcome of IVF treatment, in a pilot study. Twenty-five women were included and IVF treatment was successful for six and unsuccessful for 19 women. Blood samples were collected before IVF treatment, on four occasions during IVF and four weeks after embryo transfer. The numbers of Th1-, Th2- and Th17-associated cytokine-secreting cells and cytokine levels in cell supernatants were analysed by enzyme-linked immunospot-forming (ELISpot), enzyme-linked immune-sorbent (ELISA) or Luminex assay. None of the cytokines (IFN-γ, IL-4, IL-5, IL-10, IL-12, IL-13, IL-17, TNF and GM-CSF) had any predictive value regarding IVF outcome. The majority of the cytokines reached their peak levels at ovum pick-up, suggesting an enhancing influence of the hormonal stimulation. Pregnancy was associated with a high number of IL-4-, IL-5- and IL-13-secreting cells four weeks after ET. In conclusion, the results do not support our hypothesis of a more pronounced peripheral Th1 and Th17 deviation towards paternal antigens in infertile women with an unsuccessful IVF outcome, although this is based on a small number of observations. A larger study is required to confirm this conclusion. Higher numbers of Th2-associated cytokine-secreting cells in pregnant women four weeks after ET do corroborate the hypothesis of a Th2 deviation during pregnancy

Chemokines may contribute to the systemic inflammation that is linked to the increased risk of co-morbidities in patients with psoriasis. The aim of this study was to investigate circulating chemokines in patients with psoriasis and their relationship to disease severity. Analysis of plasma levels of chemokines in patients with psoriasis before narrowband ultraviolet B (UVB) therapy revealed increased expression of Th1-associated CXCL9 and -10, Th2-associated CCL17 and CCL22, and Th17-associated CCL20. CCL20 correlated with disease severity. UVB therapy reduced skin symptoms, but did not affect the chemokine levels in plasma. Anti-CD3 and anti-CD28-mediated activation of peripheral blood mononuclear cells (PBMCs) caused a higher secretion of Th2 cytokine interleukin (IL)-13 by PBMCs from patients with psoriasis than from healthy controls. The sustained high expression of inflammatory chemokines is a potential link to systemic inflammation in psoriasis. UVB therapy may be a more effective treatment of local rather than systemic inflammation

Type 2 T-helper cell (Th2)-skewed immunity is associated with successful pregnancy and the ability to easily direct immune responses to a Th2-polarised profile may be an evolutionary benefit. The Th2-like immunity associated with allergic disease might generate favourable effects for the maintenance of pregnancy, but could also promote development of Th2-like immune responses and allergic disease in the offspring. The aim of this study was to explore, by using IgE as a stable proxy for Th2, the Th1/Th2 balance in allergic and non-allergic women by measuring allergen-specific and total IgE antibody levels in plasma during pregnancy and after delivery. Specific and total IgE antibody levels were determined by ImmunoCAP technology at five occasions during pregnancy (gestational weeks 10-12, 15-16, 25, 35 and 39), as well as at 2 and 12 months after delivery. Thirty-six women without and 20 women with allergic symptoms were included, of whom 13 were sensitised with allergic symptoms and 30 were non-sensitised without allergic symptoms. The levels of total IgE, but not allergen-specific IgE, were increased during early pregnancy when compared to 12 months after delivery in the sensitised women with allergic symptoms, but not in the non-sensitised women without allergic symptoms (pandlt;0.01). This increase in total IgE levels during early pregnancy only in the sensitised women with allergic symptoms indicates that allergy is associated with an enhanced Th2 deviation during pregnancy.Original Publication: Martina Sandberg, Anne Frykman, Yvonne Jonsson, Marie Persson, Jan Ernerudh, Göran Berg, Leif Matthiesen, Christina Ekerfelt and Maria Jenmalm, Total and allergen-specific IgE levels during and after pregnancy in relation to maternal allergy, 2009, JOURNAL OF REPRODUCTIVE IMMUNOLOGY, (81), 1, 82-88. http://dx.doi.org/10.1016/j.jri.2009.04.003 Copyright: Elsevier Science B.V., Amsterdam. http://www.elsevier.com/</p

Functional SARS-CoV-2 cross-reactive CD4+ T cells established in early childhood decline with age.

Pre-existing SARS-CoV-2-reactive T cells have been identified in SARS-CoV-2-unexposed individuals, potentially modulating COVID-19 and vaccination outcomes. Here, we provide evidence that functional cross-reactive memory CD4+ T cell immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is established in early childhood, mirroring early seroconversion with seasonal human coronavirus OC43. Humoral and cellular immune responses against OC43 and SARS-CoV-2 were assessed in SARS-CoV-2-unexposed children (paired samples at age two and six) and adults (age 26 to 83). Pre-existing SARS-CoV-2-reactive CD4+ T cell responses targeting spike, nucleocapsid, and membrane were closely linked to the frequency of OC43-specific memory CD4+ T cells in childhood. The functional quality of the cross-reactive memory CD4+ T cell responses targeting SARS-CoV-2 spike, but not nucleocapsid, paralleled OC43-specific T cell responses. OC43-specific antibodies were prevalent already at age two. However, they did not increase further with age, contrasting with the antibody magnitudes against HKU1 (β-coronavirus), 229E and NL63 (α-coronaviruses), rhinovirus, Epstein-Barr virus (EBV), and influenza virus, which increased after age two. The quality of the memory CD4+ T cell responses peaked at age six and subsequently declined with age, with diminished expression of interferon (IFN)-γ, interleukin (IL)-2, tumor necrosis factor (TNF), and CD38 in late adulthood. Age-dependent qualitative differences in the pre-existing SARS-CoV-2-reactive T cell responses may reflect the ability of the host to control coronavirus infections and respond to vaccination
