BACKGROUND: IL-33 plays critical role in the regulation of tissue homeostasis, injury and repair. Whether IL-33 regulates neutrophil recruitment and function independently of airways hyperresponsiveness (AHR) in ozone induced lung injury and inflammation is unclear. OBJECTIVE: To examine the role of IL-33/ST2 axis in lung inflammation upon acute ozone exposure in mice. METHODS: ST2 and IL-33 deficient mice, IL-33-citrine reporter and C57BL/6 (WT) mice underwent a single ozone exposure (1 ppm for 1h) in all studies...

BACKGROUND: IL-33 is one of the most consistently associated gene candidates for asthma identified by GWAS. Studies in mice and in human cells have confirmed the importance of IL-33 in inducing type-2 cytokine production from both group 2 innate lymphoid cells (ILC2) and Th2 cells. However, there are no pharmacologic agents known to inhibit IL-33 release from airway cells. OBJECTIVE: To determine the effect of glucagon like peptide receptor-1 GLP-1R signaling on aeroallergen-induced airway IL-33 production and release and on innate type-2 airway inflammation...

BACKGROUND: Genetic variants in the chromosomal region 17q21 are consistently associated with asthma. However, mechanistic studies have not yet linked any of the associated variants to a function that could influence asthma, and as a result, the identity of the asthma gene(s) remains elusive. OBJECTIVES: We sought to identify and characterize functional variants in the 17q21 locus. METHODS: We used the Exome Aggregation Consortium (ExAC) browser to identify coding (amino acid-changing) variants in the 17q21 locus...

BACKGROUND: Heterozygous gain-of-function mutations in PI3K110 lead to lymphadenopathy, lymphoid hyperplasia, Epstein-Barr virus (EBV) and cytomegalovirus (CMV) viremia, and sinopulmonary infections. OBJECTIVE: The known role of NK cell function in the control of EBV and CMV prompted us to investigate the functional and phenotypic effect of PI3K110δ mutations on NK cell subsets and cytotoxic function. METHODS: Patient mutations were identified by whole exome or targeted sequencing...

BACKGROUND: Early-life acute respiratory infection (ARI) with respiratory syncytial virus (RSV) has been strongly associated with the development of childhood wheezing illnesses, but the pathways underlying this association are poorly understood. OBJECTIVE: To examine the role of the nasopharyngeal microbiome in the development of childhood wheezing illnesses following RSV ARI in infancy. METHODS: We conducted a nested cohort study of 118 previously healthy, term infants with confirmed RSV ARI by RT-PCR...

BACKGROUND: Expression profiling of skin biopsies has established molecular features of the skin in atopic dermatitis (AD). Invasiveness of biopsies has prevented their use in defining individual level AD pathobiological mechanisms (endotypes) in large research studies. OBJECTIVE: To determine if minimally invasive skin tape strip transcriptome analysis identifies gene expression dysregulation in AD and molecular disease endotypes. METHODS: We sampled non-lesional and lesional skin tape strips and biopsies from adult Caucasian subjects AD patients (18 males, 12 females; age (Mean±SE) 36...

Chromosome 17q12-21 remains the most highly replicated and significant asthma locus. Genotypes in the core region defined by the first GWAS correlate with expression of two genes, ORMDL3 and GSDMB, making these prime candidate asthma genes, although recent studies have implicated GSDMA distal to and PGAP3 proximal to the core region as independent loci. We review here 10 years of studies on the 17q12-21 locus and suggest that genotype-specific risks for asthma at the proximal and distal loci are not specific to early onset asthma and mediated by PGAP3, ORMDL3, and/or GSDMA expression...

BACKGROUND: Metabolites of eicosapentaenoic acid (EPA) exert various physiological actions. 17,18-epoxyeicosatetraenoic acid (17,18-EpETE) is a recently identified new class of anti-allergic and anti-inflammatory lipid metabolite of EPA, but its effects on skin inflammation and the underlying mechanisms remain to be investigated. OBJECTIVE: We evaluated the effectiveness of 17,18-EpETE for the control of contact hypersensitivity in mouse and cynomolgus macaques...

Oral immunotherapy (OIT) has reproducibly demonstrated successful desensitization in food-allergic subjects completing clinical trials and, in some studies, sustained unresponsiveness. These clinical outcomes have been associated with characteristic modifications in the allergen-specific immune response, but a detailed synthesis of OIT's mechanisms of action is lacking. In this Rostrum, we review the current evidence regarding the human immune response to OIT, explore possible mechanisms, and identify knowledge gaps for future research...

Vaccines were originally developed in order to prevent or ameliorate infectious disease. As knowledge of immune function and the appreciation of immunodeficiency has developed, researchers have used vaccine responses as a tool to characterize the phenotypes of patients exhibiting various syndromes. Thus, it has become possible for a clinician to evaluate individual responses to vaccines in order to interrogate the immunocompetence of their patients. Although there have been many advances in these areas, we still have much to learn about the quantity and quality of humoral and cellular vaccine responses in normal and immunodeficient individuals and how that knowledge may then be extrapolated to diagnostic purposes...

BACKGROUND: Histamine is a critical mediator of IgE/mast cell-mediated anaphylaxis. Histamine is synthesized by decarboxylating the amino acid histidine, a reaction catalyzed by the Hdc-gene encoded enzyme histidine decarboxylase. However, regulation of the Hdc gene in mast cells is poorly understood. OBJECTIVE: We sought to investigate the in vivo regulation of IgE/mast cell mediated anaphylaxis by transcription factors GATA2 and MITF and the mechanisms by which GATA2 and MITF regulate Hdc gene expression in mouse and human mast cells...

BACKGROUND: Although increased accumulation of neutrophils has been noted in chronic rhinosinusitis (CRS), the function and regulation of neutrophils in CRS are largely unknown. IL-36 family cytokines may play an important role in neutrophilic inflammation. OBJECTIVE: To investigate the expression and function of IL-36 cytokines in CRS. METHODS: Quantitative RT-PCR, immunohistochemistry, immunofluorescence, and ELISA were used to investigate the expression of IL-36 cytokines and IL-36 receptor (IL-36R) in sinonasal mucosa...
