BACKGROUND: Nickel (Ni) is the most frequent metal allergen and induces a TH1 -dependent type-IV allergy. Although Ni(2+) is considered to bind to endogenous proteins, it currently remains unclear whether these Ni-binding proteins are involved in Ni allergy in vivo. We previously reported the adjuvant effects of lipopolysaccharide (LPS) in a Ni allergy mouse model. Since LPS induces a number of inflammatory mediators, we hypothesized that Ni-binding protein(s) are also induced by LPS...

BACKGROUND: Allergy to the German cockroach (Blattella germanica) is a significant asthma risk factor for inner-city communities. Cockroach, like other allergens, contains trypsin-like enzyme activity that contributes to allergenicity and airway inflammation by activating proteinase-activated receptors (PARs). To date, the enzymes responsible for the proteolytic activity of German cockroach allergen have not been characterized. OBJECTIVES: We aimed to identify, isolate and characterize the trypsin-like proteinases in German cockroach allergen extracts used for clinical skin tests...

Perinatal use of Lactobacillus GG (LGG) has been associated with fewer allergic diseases, mainly eczema in high-risk children at the age of two years [1,2], a phenomenon still seen at 6-9 years [2-5]. We reported earlier that in high-risk children pre- and postnatal use of a mixture of probiotics reduced the incidence of atopic eczema at two years of age, and during the first five years atopic eczema reduction was seen in Caesarean-delivered children but not in the whole cohort [1,6]. Mothers were recruited during pregnancy and randomized at 35 weeks of gestation to the probiotic or placebo group...

BACKGROUND: We previously reported that exposure to a farming environment is allergy-protective, while high proportions of neonatal immature/naïve CD5(+) B cells and putative regulatory T cells (Tregs) are risk factors for development of allergic disease and sensitization up to 3 years of age. OBJECTIVE: To examine if B- and T-cell maturation are associated with allergic disease and farming environment over the first 8 years in life. METHODS: In the prospective FARMFLORA study, including both farming and non-farming families, 48 out of 65 children took part in the 8-year follow-up study...

BACKGROUND: The precautionary allergen labelling (PAL) and Voluntary Incidental Trace Allergen Labelling (VITAL(®) ) tools were designed by industry to assist consumers with selecting safe foods for consumption. However, a sizeable proportion of food products bear no label and it is unclear whether these products are free from allergens and therefore safe to consume or have simply not undergone a risk assessment and therefore remain unlabelled for that reason. OBJECTIVE: To assess the prevalence of unlabelled products that have undergone a risk assessment process and to examine the factors influencing industry's uptake of the VITAL(®) process...

BACKGROUND: Mesenchymal stem cells (MSCs) have multiple immunomodulatory properties and hold therapeutic potential for inflammatory diseases. However, the therapeutic and immunologic effects of human umbilical cord blood-derived MSCs (huMSCs) remain largely unexamined for asthma. OBJECTIVE: This study was to investigate the immunomodulatory properties of huMSCs in an ovalbumin (OVA)-induced murine asthma model. METHODS: Mice were injected intraperitoneally with OVA and an aluminum hydroxide adjuvant...

BACKGROUND: Methazolamide (MZ), a carbonic anhydrase inhibitor, occasionally causes Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Susceptibility to MZ-induced SJS/TEN is strongly associated with HLA-B*59:01. OBJECTIVE: To characterize the T-cell response against MZ in patients with MZ-induced SJS/TEN. METHODS: We enrolled four patients with MZ-induced SJS/TEN, performed lymphocyte transformation tests, generated MZ-specific T-cell clones, and evaluated the cytotoxic activities of these clones...

BACKGROUND: Despite extensive research, the aetiology of atopic dermatitis remains largely unknown, but reduced intestinal microbiota diversity in neonates has been linked to subsequent atopic dermatitis. Consequently, postnatal antibiotics have been proposed as a risk factor, but a potential association between prenatal antibiotics and atopic dermatitis is not well studied. Overall, the current evidence suggests a positive association between exposure to prenatal antibiotics and atopic dermatitis...

BACKGROUND: Patients with systemic mastocytosis (SM) have clinical signs of mast cell (MC) activation and increased levels of MC mediators. It is unclear whether the increased mediator levels are caused by increased numbers of tissue MCs, or whether these cells in affected individuals have a hyperactive phenotype. OBJECTIVE: To determine reactivity of the skin and the airways to directly acting mediators and indirectly acting mast cell secretagogues in subjects with SM...

BACKGROUND: Hemopoietic progenitor cells (HPC) migrate to sites of allergic inflammation where, upon stimulation with epithelial cytokines, they produce Th2 cytokines and differentiate into mature eosinophils and basophils. They also express Toll-like receptors (TLR) involved in anti-microbial responses. OBJECTIVE: The objective of this study was to compare TLR expression on peripheral blood HPC and TLR-induced responses, in particular changes in epithelial cytokine receptors, in healthy and asthmatic subjects at baseline and following allergen challenge...

BACKGROUND: Clinical desensitization and oral food immunotherapy are therapeutic interventions that allow individuals who react adversely to an allergen (drug or food) to be made tolerant to the allergen. However, tolerance is brief and allergen hypersensitivity can recur within days following allergen withdrawal. OBJECTIVE: We hypothesize that the reason these treatments are temporary reflects rapid recovery of mast cells from a desensitized state. We sought to test this...

BACKGROUND: Mono- and polysensitization are different IgE-mediated allergic phenotypes in children. Allergic sensitization is associated with both allergic asthma and allergic rhinitis, however, associations between the sensitization pattern and particularly polysensitization with asthma and rhinitis remains poorly studied in adults. AIM: The aim of this study was to assess how the allergic sensitization pattern associates with asthma, rhinitis and their multimorbidity...

BACKGROUND: Dietary antioxidant intake has been hypothesized to influence the development of allergic diseases, however, few prospective studies have investigated this association. OBJECTIVE: Our aim was to study the association between total antioxidant capacity (TAC) of the diet at age 8 years and the subsequent development of asthma, rhinitis and sensitization to inhalant allergens between 8 and 16 years, and to assess potential effect modification by known risk factors...

BACKGROUND: Perinatal maternal stress and low mood have been linked to offspring atopic eczema. OBJECTIVES: To examine the relation of maternal stress/mood with atopic eczema in the offspring, focusing particularly on stress/psychological distress preconception. METHODS: At recruitment in the UK Southampton Women's Survey, preconception maternal reports of perceived stress in daily living and the effect of stress on health were recorded; in a subsample, psychological distress was assessed (12-item General Health Questionnaire)...

BACKGROUND: Mild asthmatics who smoke cigarettes may develop unstable disease and neutrophilic infiltration of the airways, features more usually associated with severe asthmatic disease. The mechanisms giving rise to this response remain unclear. OBJECTIVE: To address the hypothesis that smoking increases bronchial mucosal production of IL-17A which acts on bronchial epithelial cells directly and in concert with other environmental stimuli to induce the production of IL-6 and neutrophil chemotaxins...

BACKGROUND: Mice models suggest epigenetic inheritance induced by parental allergic disease activity. However, we know little of how parental disease activity before conception influences offspring's asthma and allergy in humans. OBJECTIVE: We aimed to assess the associations of parental asthma severity, bronchial hyperresponsiveness (BHR), and total and specific IgEs, measured before conception vs after birth, with offspring asthma and hay fever. METHODS: The study included 4293 participants (mean age 34, 47% men) from the European Community Respiratory Health Survey (ECRHS) with information on asthma symptom severity, BHR, total and specific IgEs from 1991-1993, and data on 9100 offspring born 1972-2012...

BACKGROUND: Being born and raised in a farm provides a long-lasting protection for allergies. The microbial environment provided by farm animals is crucial to induce this protective effect, although underlying immune mechanisms remain elusive. OBJECTIVE: To establish a mouse model of global exposure to the farming environment and to study immunologic changes linked to protection of allergy. METHODS: Mice colonies were bred in parallel in a farm cowshed and the University animal facility (AF)...

BACKGROUND: The antioxidant hypothesis regarding the risk of asthma in childhood has resulted in inconsistent findings. Some data indicate that the role of antioxidants in childhood asthma risk may have a critical time window of effect, but only a well-designed longitudinal cohort study can clarify this hypothesis. OBJECTIVE: To study the longitudinal associations between serum carotenoid and tocopherol concentrations during the first 4 years of life and asthma risk by the age of 5 years...

BACKGROUND: Children with risk alleles at the 17q21 genetic locus who wheeze during rhinovirus illnesses have a greatly increased likelihood of developing childhood asthma. In mice, overexpression of the 17q21 gene ORMDL3 leads to airway remodeling and hyper-responsiveness. However, the mechanisms by which ORMDL3 predisposes to asthma are unclear. Previous studies have suggested that ORMDL3 induces endoplasmic reticulum (ER) stress and production of the type I interferon (IFN) regulated chemokine CXCL10...
