BACKGROUND: Seasonal allergic rhinitis (SAR) as a result of intermittent exposure to seasonal pollen, causes itching, nasal congestion and repeated sneezing, with profound effects on the quality of life, work productivity and school performance. While both the genotype and environmental factors may contribute to the immunological basis of allergic reactions, the molecular underpinnings associated with the pathogenesis of allergic rhinitis are not entirely clear. METHODS: To address these questions, nasal epithelial brushings were collected from 29 SAR and 31 Control individuals during and after the pollen season...

This is the first demonstration of RNA-containing exosomes in induced sputum from allergic asthmatic patients, both before and after an allergen provocation. Exosomes could serve as future candidate biomarkers in asthma.

BACKGROUND: Clonal mast cell disorders are known to occur in a subset of patients with systemic reactions to Hymenoptera stings. This observation has prompted the question as to whether clonal mast cell disorders also occur in patients with idiopathic anaphylaxis (IA). OBJECTIVE: We sought to determine the prevalence of clonal mast cell disorders among patients with IA, criteria to identify those patients who require a bone marrow biopsy and whether the pathogenesis of IA involves a hyper-responsive mast cell compartment...

Individuals experience distinct patterns of atopic dermatitis disease control over time; female sex, lower income, non-white race, atopic history and earlier age of onset were highly predictive of persistently active disease into early adulthood.

Monocytes from sepsis patients have mitochondrial DNA (mtDNA) depletion and immune deactivation. Here we find that THP-1 cell immune responses are impaired by experimentally depleting mtDNA, through dysregulated immune signalling, and rescued by interferon-γ treatment.

BACKGROUND: Autosomal dominant anhidrotic ectodermal dysplasia with immune deficiency (AD EDA-ID) is caused by heterozygous point mutations at or close to S32 and S36 or N-terminal truncations in IκBα that impair its phosphorylation and degradation, and thus activation of the canonical NF-κB pathway. The outcome of hematopoietic stem cell transplantation is poor in AD EDA-ID despite achievement of chimerism. Mice heterozygous for the S32I mutation in IκBα have impaired non-canonical NF-κB activity and defective lymphorganogenesis...

BACKGROUND: Childhood exposure to a farm environment has been shown to protect against the development of inflammatory diseases such as allergy, asthma, and inflammatory bowel disease. OBJECTIVE: We sought to investigate whether besides exposure to microbes also exposure to structures of non-microbial origin such as the sialic acid N-Glycolylneuraminic acid (Neu5Gc) may play a significant role. METHODS: Exposure to Neu5Gc was evaluated by quantifying anti-Neu5Gc antibody levels in the sera of children enrolled in two farm studies: the PARSIFAL study (n=299) and the PASTURE birth cohort (cord blood (n=836), 1 year (n=734), 4...

BACKGROUND: Mannose receptor (MRC1/CD206) has been suggested to mediate allergic sensitization and asthma to multiple glyco-allergens, including cockroach allergens. OBJECTIVE: Determine the existence of a protective mechanism through which MRC1 limits allergic inflammation through its intronic miR-511-3p. METHODS: We examined the MRC1-mediated cockroach allergen uptake by lung macrophages and lung inflammation using C57BL/6 wild-type (WT) and Mrc1(-/-) mice...

We found associations between FA and 14 GWAS-identified loci of AD and EoE: C11orf30/LRRC32, TMEM232/SLC25A46, TNFRSF6B/ZGPAT, OVOL1, KIF3A/IL13, GLB1, CCDC80, ZNF365, OR10A3/NLRP10, IL2/IL21, CLEC16A/DEXI, ZNF652, TSLP/WDR36 and STAT6. These findings improve our understanding of the complex heterogeneity of FA.

BACKGROUND: Immunoglobulin D (IgD) is an enigmatic antibody isotype best known when co-expressed with IgM on naïve B cells. However, elevated soluble IgD (sIgD) and increased IgD(+)IgM(-) B cell populations have been described in the human upper respiratory mucosa. OBJECTIVE: We assessed whether levels of sIgD and IgD(+) B cells are altered in nasal tissue from patients with chronic rhinosinusitis (CRS). We further characterized IgD(+) B cell populations and explored clinical and local inflammatory factors associated with tissue sIgD levels...

The PPAR-γ agonist, pioglitazone, was associated with significant side effects and did not improve the primary outcome measure of the Juniper Asthma Quality of Life Questionnaire (AQLQ) score in severe asthmatics. We conclude that no further studies should be performed with pioglitazone for severe asthma.

This study demonstrates the responsiveness of the Urticaria Control Test (UCT). Changes of its score by 3 points or more reflect a clinically relevant change of disease control (minimal important difference).

BACKGROUND: Mast cells (MCs), the primary effector cell of the atopic response, participate in immune defense at host/environment interfaces, yet the mechanisms by which they interact with CD4(+)-T cells has been controversial. OBJECTIVE: We utilize in situ-matured primary human MCs and matched CD4(+)-T cells to diligently assess the ability of MCs to act as antigen-presenting cells. METHODS: We examined mature human skin-derived MCs by flow cytometry for expression of antigen-presenting molecules; for their ability to stimulate CD4(+)-T cells to express CD25 and proliferate when exposed to superantigen or to CMV antigen using matched T cells and MCs from CMV seropositive or seronegative donors; and for uptake of antigens...

BACKGROUND: The inhibitory receptor, FcγRIIB, is expressed on human and murine bone marrow-derived cells and limits inflammation by suppressing signaling through stimulatory receptors. OBJECTIVE: Evaluate the effects of K9.361, a mouse IgG2a alloantibody to mouse FcγRIIB, on murine anaphylaxis. METHODS: Wild-type and FcγR-deficient mice were used to study anaphylaxis, which was induced by injection of 2.4G2 (rat IgG2b mAb that binds both FcγRIIB and the stimulatory receptor, FcγRIII); by actively immunizing IgE-deficient mice, then challenging with the immunizing Ag; and by passive immunization with IgG or IgE anti-TNP mAb, followed by injection of TNP-ovalbumin...
