Interleukin-8 receptor modulates IgE production and B-cell expansion and trafficking in allergen-induced pulmonary inflammation. (1/3663)We examined the role of the interleukin-8 (IL-8) receptor in a murine model of allergen-induced pulmonary inflammation using mice with a targeted deletion of the murine IL-8 receptor homologue (IL-8r-/-). Wild-type (Wt) and IL-8r-/- mice were systemically immunized to ovalbumin (OVA) and were exposed with either single or multiple challenge of aerosolized phosphate-buffered saline (OVA/PBS) or OVA (OVA/OVA). Analysis of cells recovered from bronchoalveolar lavage (BAL) revealed a diminished recruitment of neutrophils to the airway lumen after single challenge in IL-8r-/- mice compared with Wt mice, whereas multiply challenged IL-8r-/- mice had increased B cells and fewer neutrophils compared with Wt mice. Both Wt and IL-8r-/- OVA/OVA mice recruited similar numbers of eosinophils to the BAL fluid and exhibited comparable degrees of pulmonary inflammation histologically. Both total and OVA-specific IgE levels were greater in multiply challenged IL-8r-/- OVA/OVA mice than in Wt mice. Both the IL-8r-/- OVA/OVA and OVA/PBS mice were significantly less responsive to methacholine than their respective Wt groups, but both Wt and IL-8r mice showed similar degrees of enhancement after multiple allergen challenge. The data demonstrate that the IL-8r modulates IgE production, airway responsiveness, and the composition of the cells (B cells and neutrophils) recruited to the airway lumen in response to antigen.

Molecular cloning and epitope analysis of the peanut allergen Ara h 3. (2/3663)Peanut allergy is a significant IgE-mediated health problem because of the increased prevalence, potential severity, and chronicity of the reaction. Following our characterization of the two peanut allergens Ara h 1 and Ara h 2, we have isolated a cDNA clone encoding a third peanut allergen, Ara h 3. The deduced amino acid sequence of Ara h 3 shows homology to 11S seed-storage proteins. The recombinant form of this protein was expressed in a bacterial system and was recognized by serum IgE from approximately 45% of our peanut-allergic patient population. Serum IgE from these patients and overlapping, synthetic peptides were used to map the linear, IgE-binding epitopes of Ara h 3. Four epitopes, between 10 and 15 amino acids in length, were found within the primary sequence, with no obvious sequence motif shared by the peptides. One epitope is recognized by all Ara h 3-allergic patients. Mutational analysis of the epitopes revealed that single amino acid changes within these peptides could lead to a reduction or loss of IgE binding. By determining which amino acids are critical for IgE binding, it might be possible to alter the Ara h 3 cDNA to encode a protein with a reduced IgE-binding capacity. These results will enable the design of improved diagnostic and therapeutic approaches for food-hypersensitivity reactions. (+info)
Cockroach allergy and asthma in a 30-year-old man. (3/3663)A growing body of evidence has implicated allergens derived from cockroaches as an important environmental factor that may aggravate asthma in sensitized persons. We present the case of a 30-year-old man with asthma and a cockroach allergy. Allergy skin testing confirmed hypersensitivity to cockroach extract, and a home visit revealed visual evidence of infestation and the presence of Bla g 1 German cockroach allergen in vacuumed dust. As is typical of patients with a cockroach allergy and asthma, multiple factors in addition to cockroach allergen appeared to aggravate the patient's asthma. A multimodality therapeutic regimen, which included medications as well as cleaning of the home, integrated pest management, and professional application of chemical controls, resulted in substantial clinical improvement. The pathophysiology, epidemiology, and clinical features of cockroach-allergic asthma are reviewed, and an approach to diagnosis and management is suggested. (+info)
Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness. (4/3663)Exhaled nitric oxide is a potential marker of lower airway inflammation. Allergic rhinitis is associated with asthma and bronchial hyperresponsiveness. To determine whether or not nasal and exhaled NO concentrations are increased in allergic rhinitis and to assess the relation between hyperresponsiveness and exhaled NO, 46 rhinitic and 12 control subjects, all nonasthmatic nonsmokers without upper respiratory tract infection, were randomly selected from a large-scale epidemiological survey in Central Norway. All were investigated with flow-volume spirometry, methacholine provocation test, allergy testing and measurement of nasal and exhaled NO concentration in the nonpollen season. Eighteen rhinitic subjects completed an identical follow-up investigation during the following pollen season. Exhaled NO was significantly elevated in allergic rhinitis in the nonpollen season, especially in perennially sensitized subjects, as compared with controls (p=0.01), and increased further in the pollen season (p=0.04), mainly due to a two-fold increase in those with seasonal sensitization. Nasal NO was not significantly different from controls in the nonpollen season and did not increase significantly in the pollen season. Exhaled NO was increased in hyperresponsive subjects, and decreased significantly after methacholine-induced bronchoconstriction, suggesting that NO production occurs in the peripheral airways. In allergic rhinitis, an increase in exhaled nitric oxide on allergen exposure, particularly in hyperresponsive subjects, may be suggestive of airway inflammation and an increased risk for developing asthma.

Compliance and stability of the bronchial wall in a model of allergen-induced lung inflammation. (5/3663)Airway wall remodeling in response to inflammation might alter load on airway smooth muscle and/or change airway wall stability. We therefore determined airway wall compliance and closing pressures in an animal model. Weanling pigs were sensitized to ovalbumin (OVA; ip and sc, n = 6) and were subsequently challenged three times with OVA aerosol. Control pigs received 0.9% NaCl (n = 4) in place of OVA aerosol. Bronchoconstriction in vivo was assessed from lung resistance and dynamic compliance. Semistatic airway compliance was recorded ex vivo in isolated segments of bronchus, after the final OVA aerosol or 0.9% NaCl challenge. Internally or externally applied pressure needed to close bronchial segments was determined in the absence or presence of carbachol (1 microM). Sensitized pig lungs exhibited immediate bronchoconstriction to OVA aerosol and also peribronchial accumulations of monocytes and granulocytes. Compliance was reduced in sensitized bronchi in vitro (P < 0.01), and closing pressures were increased (P < 0.05). In the presence of carbachol, closing pressures of control and sensitized bronchi were not different. We conclude that sensitization and/or inflammation increases airway load and airway stability.

A genome-wide screen for asthma-associated quantitative trait loci in a mouse model of allergic asthma. (6/3663)Asthma is the most common illness of childhood, affecting one child in seven in the UK. Asthma has a genetic basis, but genetic studies of asthma in humans are confounded by uncontrolled environmental factors, varying penetrance and phenotypic pleiotropy. An animal model of asthma would offer controlled exposure, limited and consistent genetic variation, and unlimited size of sibships. Following immunization and subsequent challenge with ovalbumin, the Biozzi BP2 mouse shows features of asthma, including airway inflammation, eosinophil infiltration and non-specific bronchial responsiveness. In order to identify genetic loci influencing these traits, a cross was made between BP2 and BALB/c mice, and a genome-wide screen carried out in the F2progeny of the F1intercross. Five potentially linked loci were identified, four of which corresponded to human regions of syntenic homology that previously have shown linkage to asthma-associated traits. (+info)
Strain-dependent induction of allergic sensitization caused by peanut allergen DNA immunization in mice. (7/3663)To investigate the potential application of allergen gene immunization in the modulation of food allergy, C3H/HeSn (C3H) mice received i.m. injections of pAra h2 plasmid DNA encoding one of the major peanut allergens, Ara h2. Three weeks following pDNA immunization, serum Ara h2-specific IgG2a, IgG1, but not IgE, were increased significantly in a dose-dependent manner. IgG1 was 30-fold higher in multiply compared with singly immunized mice. Ara h2 or peanut protein injection of immunized mice induced anaphylactic reactions, which were more severe in multiply immunized mice. Heat-inactivated immune serum induced passive cutaneous anaphylaxis, suggesting that anaphylaxis in C3H mice was mediated by IgG1. IgG1 responses were also induced by intradermal injection of pAra h2, and by i.m. injection of pOMC, the plasmid DNA encoding the major egg allergen protein, ovomucoid. To elucidate whether the pDNA immunization-induced anaphylaxis was a strain-dependent phenomenon, AKR/J and BALB/c mice also received multiple i.m. pAra h2 immunizations. Injection of peanut protein into these strains at weeks 3 or 5 following immunization did not induce reactions. Although IgG2a was increased significantly from week 2 in AKR/J mice and from week 4 in BALB/c mice and remained elevated for at least 6 wk, no IgG1 or IgE was detected. These results indicate that the type of immune responses to pDNA immunization in mice is strain dependent. Consequently, models for studying human allergen gene immunization require careful selection of suitable strains. In addition, this suggests that similar interindividual variation is likely in humans. (+info)
Process and current status of the epidemiologic studies on cedar pollinosis in Japan. (8/3663)This paper reviews the present situation and future aspects of epidemiologic studies on Japanese cedar pollinosis. Increase of allergic rhinitis patients is observed in both the Patient Survey and the Reports on the Surveys of Social Medical Care Insurance Services, however, these surveys are conducted when cedar pollens do not pollute the air. Many have reported on the prevalence of pollinosis in limited areas but only a few nationwide epidemiologic surveys have been conducted. Most of the studies were conducted at special medical facilities such as university hospitals. There is a high possibility that patients who visit the specific facilities do not exactly represent the actual number of patients and epidemiologic pictures of pollinosis in Japan. The rapid advances in laboratory test methods may change the diagnostic criteria and increase the number of reported patients. Therefore, the prevalence of Japanese cedar pollinosis in Japan has not been determined yet. Determination of the prevalence of cedar pollinosis and description of the epidemiologic pictures constitute the essential steps toward the control of this clinical entity. Thus it is necessary to conduct an epidemiologic survey on Japanese representative samples with a standardized survey form with clear and concise diagnostic criteria. (+info)

MicroRNAs are small non-coding RNAs that regulate gene expression at the post-transcriptional level. While they have been implicated in various diseases, the profile changes in allergen inhalation challenge are not clarified in human. We aimed to evaluate changes in the microRNA profiles in the peripheral blood of asthmatic subjects undergoing allergen inhalation challenge. Seven mild asthmatic subjects participated in the allergen inhalation challenge. In addition, four healthy control subjects (HCs) were recruited. MicroRNA profiles in peripheral blood samples (pre-challenge and 2 hours post-challenge) were measured by the NanoString nCounter assay to determine changes in miRNA levels as these asthmatic subjects underwent an allergen inhalation challenge. One common miRNA, miR-192, was significantly expressed in both comparisons; HCs vs. pre-challenge and pre- vs. post-challenge, showing that miR-192 was significantly under-expressed in asthmatics compared to HCs and decreased in post-challenge at an

Methods: Five patients with ragweed-allergic asthma underwent bronchoscopy and segmental bronchial challenge with either normal saline or short ragweed extract in two segments of one lung. In a third segment of the opposite lung, 12 successive BALs ...
p,Asthma is a chronic respiratory disease which is characterized by reversible bronchoconstriction, airway hyperresponsiveness, and airway inflammation. Allergen inhalation by sensitized atopic asthmatics enhances airway hyperresponsiveness and inflammation, providing a model to study mild asthma exacerbation. Airway inflammation can be measured non-invasively from airway secretions by sputum induction. Prior to starting this thesis, information on allergen-induced inflammation measured from sputum was limited. Furthermore, the pro- or anti-inflammatory effects of asthma therapies had not been investigated using this model of allergen-induced airway inflammation. The aim of this thesis was to first characterize the allergen-induced changes in sputum inflammatory cells and determine the repeatability of measurements of sputum inflammatory cells following allergen inhalation challenge. In addition, this thesis was aimed to investigate the pro- or anti-inflammatory effects of asthma therapies on ...
Allergen exposure leads to allergen sensitization in susceptible individuals and this might influence allergic rhinitis (AR) phenotype expression. We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age. In a national, cross-sectional study AR patients (2-70 y) seen by allergists underwent blinded skin prick testing with a panel of 18 allergens and completed a validated questionnaire on AR phenotypes. 628 patients were recruited. The major sensitizing allergen was house dust mite (HDM) (56%), followed by Bermuda grass (26%), ash (24%), oak (23%) and mesquite (21%) pollen, cat (22%) and cockroach (21%). Patients living in the tropical region were almost exclusively sensitized to HDM (87%). In the central agricultural zones sensitization is primarily to grass and tree pollen. Nationwide, most study subjects had perennial (82.2%), intermittent (56.5%) and moderate-severe (84.7%) AR. Sensitization was
BACKGROUND: The cysteinyl leukotrienes (LTC4, LTD4 and LTE4) have been implicated in the pathogenesis of allergen-induced airway responses. The effects of pretreatment with BAYx 1005, an inhibitor of leukotriene biosynthesis via antagonism of 5-lipoxygenase activating protein, on allergen-induced early and late asthmatic responses has been evaluated. METHODS: Eight atopic subjects with mild asthma participated in a two period, double blind, placebo controlled, cross-over trial. Subjects were selected on the basis of a forced expiratory volume in one second (FEV1) of , 70% predicted, a methacholine provocative concentration causing a 20% fall in FEV1 (PC20) of , 32 mg/ ml, a documented allergen-induced early response (EAR, , 15% fall in FEV1 0-1 hour after allergen inhalation) and late response (LAR, , 15% fall in FEV1 3-7 hours after allergen inhalation), and allergen-induced airway hyperresponsiveness (at least a doubling dose reduction in the methacholine PC20 30 hours after allergen ...
Using a combination of in vitro and in vivo experiments and both artificial and natural allergen particles, we have presented evidence that the cross-linking of IgE/FcεRI complexes on MCs by particulate allergens induces not only MC degranulation but also phagocytosis of the activating allergens. Following phagocytosis, the allergens avoid intracellular degradation and acquire the potential for extracellular release. This remarkable phenomenon is directly attributable to lipid raft-mediated phagocytosis of allergen followed by the conversion of allergen-containing phagosomes into secretory compartments within the cells. Evidence that the IgE/FcεRI-mediated MC phagocytosis of particulate allergens involves lipid raft entities comes from the observations that: 1) the phagocytic event is preceded by the association of IgE/FcεRI complexes with lipid rafts; and 2) the disruption of lipid rafts in MCs blocked the phagocytosis of allergens. Lipid rafts have previously been reported to be essential ...
Expression of pulmonary eotaxin protein and mRNA was determined in six subjects with atopic asthma and five nonatopic normal subjects. Levels of eotaxin expression and eosinophil mobilization were compared before and after segmental allergen challenge in subjects with atopic asthma. In the absence o …
Researchers suspect that allergies to common inhaled allergens (such as house dust mite, cat dander, and grass pollens) are a major cause of childhood asthma. Recent evidence suggests that if allergies to inhaled allergens are prevented, this can cause changes in the immune system that may inhibit the development of asthma. Although strategies to prevent allergies generally focus on avoiding the allergen, complete avoidance of the common allergens linked to asthma would require extreme measures and is impractical.. Oral mucosal immunoprophylaxis (OMIP) therapy is an allergy treatment that can induce long-lasting immune tolerance in people already suffering from allergies. By exposing the patient to small, repeated, but increasing doses of the problem allergen over a long period of time, the patients immune system is eventually desensitized to that particular allergen. OMIP therapy has been shown to be safe in children as young as 2 years old. This study will evaluate if OMIP therapy against ...

The AOAC Food Allergen Community has published its first newsletter for 2017, with a focus on reference materials for food allergen analysis. Contributing author Roland Poms from MoniQA Association describes the first validated set of reference materials, commercially released in January 2017. Katharina Scherf from the German Institute for Food Chemistry provides details about her investigations into gluten protein types from wheat, rye, barley and oats that can be used as reference materials.. As Editorial Board Member Bert Popping points out in his introductory comments, there are several factors that complicate the development of standardized reference materials for allergen analysis. For example, peanuts in USA and China can be significantly different in their composition, while internationally-standardised reference materials for allergen analysis must reflect what is currently traded on the market as a food ingredient.. While several food allergen reference materials have been developed ...
Allergen analysis is central to implementing and monitoring food allergen risk assessment and management processes by the food industry but current methods for determination of allergens in foods give highly variable results. The EU-funded iFAAM project has been working to address gaps in knowledge regarding food allergen management and analysis, including the development of novel mass spectrometry (MS) and immuno -based allergen determination methods. Common allergenic food ingredients (peanut, hazelnut, walnut, cows milk and hens egg) and common food matrices (chocolate dessert and cookie) have been used for both clinical studies and analytical method development to ensure that the new methods are clinically relevant. Allergen molecules have been used as analytical targets and allergenic ingredients incurred into matrices at levels close to reference doses that may trigger the use of precautionary allergen labelling. An inter-laboratory method comparison has been undertaken for the ...
TY - JOUR. T1 - IgE sensitization patterns to commonly consumed foods determined by skin prick test in Korean adults. AU - Kim, Sung Ryeol. AU - Park, Hye Jung. AU - Park, Kyung Hee. AU - Lee, Jae Hyun. AU - Park, Jung Won. PY - 2016. Y1 - 2016. N2 - Offending food allergens can vary with regional preferences in food consumption. In this study, we analysed sensitization rates to commonly consumed foods in Korean adults suspected of having food allergy. One hundred and thirty four subjects underwent a skin prick test (SPT) with 55 food allergens, of which 13 were made by our laboratory and the rest were commercially purchased. Of the 134 patients, 73 (54.5%) were sensitized to one or more food allergens. Sensitization to chrysalis was detected most frequently, at a rate of 25.4%. Sensitization rates to other food allergens were as follows: maize grain (13.4%), shrimp (11.9%), almond (11.1%), wheat flour (8.2%), lobster (8.2%), buckwheat (8.2%), mackerel (5.2%), pollack (5.2%), halibut (4.5%), ...
Detect possible allergic responses to various substances in the environment and evaluate for hay fever, asthma, atopic eczema, and respiratory allergy. The quantitative allergen-specific IgE test is indicated (1) to determine whether an individual has elevated allergen-specific IgE antibodies; (2) if specific allergic sensitivity is needed to allow immunotherapy to be initiated; (3) when testing individuals for agents that may potentially cause anaphylaxis; (4) when evaluating individuals who are taking medication (eg, long-acting antihistamines) that may interfere with other testing modalities (eg, skin testing); (5) if immunotherapy or other therapeutic measures based on skin testing results have not led to a satisfactory remission of symptoms; (6) when an individual is unresponsive to medical management where identification of offending allergens may be beneficial. ...
That exposure to high levels of house dust mite allergen was associated with deteriorating BHR was not an unexpected finding. House dust mite allergens include a number of proteases and trypsins that may disrupt cell membranes and have direct pro-inflammatory actions, and they also mediate airway inflammation through IgE activation . They may therefore contribute to the persistence of airway inflammation over time, and perhaps a consequent increase in bronchial hyperresponsiveness.. Early-life exposure to dogs is associated with a reduced likelihood of developing asthma in children, but there are no data for adults with asthma. It is interesting therefore that we have found an association between exposure to high levels of dog allergen and improvement of BHR. We considered the possibility that subjects may have gotten rid of their dog between visits, but even after controlling for this, we discovered that the association remained the same. It is also possible that dog ownership per se ...
Food allergens continue to be a significant issue for FSIS. From 2008 through 2013, there has been a sustained increase in the number of recalls of FSIS-regulated product that contained undeclared allergens. The proportion of recalls attributed to undeclared allergens and ingredients of public health concern has also increased, from 13% in 2008 to 35% in 2012. Furthermore, 14% of undeclared allergen recalls from 2000 through 2012 were the result of investigations following consumer complaints, 9 of which were associated with reports of allergic reactions.. The trend of allergen recalls in FDA-regulated products from fiscal year 2007 through 2012 follows a similar increasing trend over time, with the exception of fiscal year 20091. Approximately 12% of the 732 allergen recalls over the six year study period resulted from the report of a consumer reaction1.. In a 2001 study, of individuals with self-reported food allergies who recalled their last allergic reaction to food, approximately 50% ...
The mechanisms by which immune responses to nonpathogenic environmental antigens lead to either allergy or nonharmful immunity are unknown. Single allergen-specific T cells constitute a very small fraction of the whole CD4(+) T cell repertoire and can be isolated from the peripheral blood of humans according to their cytokine profile. Freshly purified interferon-gamma-, interleukin (IL)-4-, and IL-10-producing allergen-specific CD4(+) T cells display characteristics of T helper cell (Th)1-, Th2, and T regulatory (Tr)1-like cells, respectively. Tr1 cells consistently represent the dominant subset specific for common environmental allergens in healthy individuals; in contrast, there is a high frequency of allergen-specific IL-4-secreting T cells in allergic individuals. Tr1 cells use multiple suppressive mechanisms, IL-10 and TGF-beta as secreted cytokines, and cytotoxic T lymphocyte antigen 4 and programmed death 1 as surface molecules. Healthy and allergic individuals exhibit all three ...
The availability of allergen molecules (components) from several protein families has advanced our understanding of immunoglobulin E (IgE)-mediated responses and enabled component-resolved diagnosis (CRD). The European Academy of Allergy and Clinical Immunology (EAACI) Molecular Allergology Users Guide (MAUG) provides comprehensive information on important allergens and describes the diagnostic options using ... read more CRD. Part A of the EAACI MAUG introduces allergen molecules, families, composition of extracts, databases, and diagnostic IgE, skin, and basophil tests. Singleplex and multiplex IgE assays with components improve both sensitivity for low-abundance allergens and analytical specificity; IgE to individual allergens can yield information on clinical risks and distinguish cross-reactivity from true primary sensitization. Part B discusses the clinical and molecular aspects of IgE-mediated allergies to foods (including nuts, seeds, legumes, fruits, vegetables, cereal grains, ...

SDAP (Structural Database of Allergenic Proteins) is a Web server that provides database information and various cobputational tools for the study of allergenic proteins. The database component of SDAP contains information the allergen name, source, sequence, structure, IgE epitopes, and literature references, and links to the major protein (PDB, SWISS-PROT, PIR, NCBI) and literature (PubMed, MEDLINE) servers. The computational component in SDAP uses an original algorithm based on conserved properties of amino acid side chains to identify regions of known allergens similar to user-supplied peptides or selected from the SDAP database of IgE epitopes. This and other bioinformatics tools can be used to rapidly determine potential cross-reactivities between allergens and to screen novel proteins for the presence of IgE epitopes they may share with known allergens. SDAP was developed guided by the allergens list from the IUIS (International Union of Immunological Societies) website, ...
A radioimmune method based on detection of IgE antibodies (RAST) has been used for allergen quantitation, both as a direct test and as an inhibition test. Commercially available allergen extracts from birch pollen, timothy pollen and horse dandruff were studied. Variations of the allergen concentration up to a thousandfold were found between some extracts and these differences were confirmed by the results obtained with the chopped human lung test and in provocation tests. The use of RAST for estimation of allergen concentrations seems to be of great value, since the method combines easy performance with high capacity and independence of allergic patients as test objects. The same set of test sera can be used for several years, ensuring standardized conditions.. ...
Figure 4. Contact dermatitis to gold is seen in areas of skin where eye makeup, foundation or sunscreens containing harder metals (eg, titanium, zinc) are applied.. Conclusion. The Allergen of the Year is an annual "award" of dubious distinction voted upon by members of the ACDS. When Ponciano Cruz, MD, created the section, the original intent was to call attention to individual allergens and specifically draw attention to allergens that are very common, underrecognized, merit more attention (because they are causing significant ACD) and are no longer causing significant relevant disease (as in thimerosal in the United States). The core intent is academic in nature - to highlight societal and public awareness. Nominations for the Allergen of the Year are solicited from the ACDS, and final determination is made through a committee, chaired by Donald Belsito, MD. Afterwards, an expert on the allergen is selected to review and author a manuscript on the allergen for publication in Dermatitis. ...
Immunoglobulin E (IgE)-mediated allergy occurs when our immune system causes a reaction to otherwise harmless substances (allergens). Allergens are predominantly proteins present in biological materials such as pollens, mites, animal epithelia, moulds and foods. In vitro tests for specific IgE antibodies usually employ an allergen source extract as an antibody capturing reagent. The proportion of allergenic molecules in these biochemically complex extracts may vary.. Recombinant allergens may be obtained in large quantities with biotechnological techniques. These proteins can be characterized biochemically and immunologically, resulting in tests with minimal batch-to-batch variation. This thesis describes different uses of recombinant allergens in component-resolved diagnostics (CRD).. In CRD, single allergenic proteins are used to establish a sensitization profile of the patient. Two timothy grass (Phleum pratense) pollen allergens, Phl p 11 and Phl p 4, were cloned and expressed as recombinant ...

Egg proteins represent one of the most important sources evoking food allergic reactions. In order to improve allergy diagnosis, purified and well-characterized proteins are needed. Although the egg white allergens Gal d 1, 2, 3 and 4 (ovomucoid, ovalbumin, ovotransferrin, and lysozyme) are commercially available, these preparations contain impurities, which affect exact in vitro diagnosis. The aim of the present study was to set up further purification protocols and to extend the characterization of the physicochemical and immunological properties of the final batches. The egg white allergens Gal d 1-4 were purified from commercial preparations, whereas Gal d 5 (a-livetin) was purified from egg yolk. The final batches of Gal d 1-5 consisted of a range of isoforms with defined tertiary structure. In addition, the IgE binding capacity of the purified egg allergens was tested using allergic patients sera. The allergen batches will be further used to set up allergen specific diagnostic assays and ...
Due to the amount of air a whole house fan moves when properly sized to the home, dust does not have any time to settle in the home! Most customer, even in the dustiest of area, do not notice a big increase in the amount of dust in the home.. As well, because the fan moves so much air, it is taking any allergens that may be inside or outside the home and exhausting it so fast they have no chance to circulate inside of the home. The fan sucks any allergens into the attic and then exhausts it through the attic vents. In fact, the allergens inside the home can be much worse than the allergens outside of the home. We even have some customers who have very bad allergies state that their allergies almost went away after installing the QuietCool!. For customers that are still concerned with bringing in dust or allergens, we have a new product to help. We have partnered with PollenTec, a manufacturer of window screens that block 99.9% of dust and allergens from entering the home. The screens are very ...
TY - JOUR. T1 - Effects of overexpression of IL-10, IL-12, TGF-β and IL-4 on allergen induced change in bronchial responsiveness. AU - Fu, Chi Ling. AU - Ye, Yi Ling. AU - Lee, Yueh L.. AU - Chiang, Bor Luen. PY - 2006/5/8. Y1 - 2006/5/8. N2 - Background: An increasing prevalence of allergic diseases, such as atopic dermatitis, allergic rhinitis and bronchial asthma, has been noted worldwide. Allergic asthma strongly correlates with airway inflammation caused by the unregulated production of cytokines secreted by allergen-specific type-2 T helper (Th2) cells. This study aims to explore the therapeutic effect of the airway gene transfer of IL-12, IL-10 and TGF-β on airway inflammation in a mouse model of allergic asthma. Methods: BALB/c mice were sensitized to ovalbumin (OVA) by intr aperitoneal injections with OVA and challenged by nebulized OVA. Different cytokine gene plasmids or non-coding vector plasmids were instilled daily into the trachea up to one day before the inhalatory OVA ...
TY - CHAP. T1 - Validation by Mass Spectrometry Food Allergen Analysis: Detection, Quantification and Validation by Mass Spectrometry. AU - Planque, Mélanie. AU - Arnould, Thierry. AU - Gillard, Nathalie. PY - 2017/10/4. Y1 - 2017/10/4. N2 - Worldwide, food-allergy-related diseases are a signi cant health problem. While the food industry works on managing cross-contaminations and while clinicians deal with treatment, laboratories must develop e cient analytical methods to ensure detection of hidden allergens that can cause severe adverse reactions. Over the past few years, huge progress has been made in mass spectrometry for the analysis of allergens in incurred and processed foodstu s, especially as regards sample preparation and enrichment (solid phase extraction, protein precipitation and ultra ltration). These achievements make it possible to meet the Allergen Bureaus Voluntary Incidental Trace Allergen Labelling (VITAL) sensitivity criteria. The present chapter details the di erent steps ...
Testing for IgE antibodies may be useful to establish the diagnosis of an allergic disease and to define the allergens responsible for eliciting signs and symptoms.. Testing also may be useful to identify allergens which may be responsible for allergic disease and/or anaphylactic episode, to confirm sensitization to particular allergens prior to beginning immunotherapy, and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.. ...
Ambient inhalable particulate matter acts as an efficient carrier of allergens allowing penetration deep into the distal airways. Epidemiological studies have shown an association between the increased incidence of asthma and levels of ambient particulate matter from air pollutants. Most experimental models investigating the pathogenesis of allergic asthma have used soluble allergens (sAgs) whereas knowledge is limited regarding the responses evoked by particulate allergens (pAgs). In this study, pathological responses to sAgs were compared with the same amount of allergens adsorbed on to the surface of polystyrene particles, in sensitised mice.. Regardless of allergen type, airways hyper-responsiveness and eosinophil infiltration were significantly greater with pAgs compared with sAgs. The response was blunted in mast cell (MC)-deficient mice suggesting that MCs are crucial in this response. MCs were able to distinguish between pAgs and sAgs. A fivefold greater MC IgE receptor-mediated response ...
We report that Il4-hemizygous mice exhibited severely compromised IgE responses but not IgG responses against OVA or hapten in OVA/Alum or hapten-OVA/Alum immunization models. Serum OVA or hapten-specific IgE was diminished by 10-100 fold in Il4-hemizygous mice, 6-fold fewer hapten-specific IgE ASC were generated, and hapten-specific IgE levels on mast cells and basophils were reduced 3-10 fold following immunization of Il4-hemizygous mice. The reduced levels of IL-4 produced by in vitro restimulated IL-4G4/+ CD4+ T cells from allergen-immunized Il4-hemizygous mice supports the notion that it is the reduced amount of IL-4 produced by the lymph node CD4+ T cell compartment that leads to the IgE deficiency.. In addition to reduced IgE production, Il4-hemizygous mice were also protected from IgE-dependent oral allergen-induced diarrhea, but remained susceptible to i.v.-induced Ab-mediated active systemic anaphylaxis. Given that both the production of IgE and mastocytosis is a necessary step for ...

Specific allergy vaccination is an efficient treatment for allergic disease; however, the development of safer vaccines would enable a more general use of the treatment. Determination of molecular structures of allergens and allergen-Ab complexes facilitates epitope mapping and enables a rational approach to the engineering of allergen molecules with reduced IgE binding. In this study, we describe the identification and modification of a human IgE-binding epitope based on the crystal structure of Bet v 1 in complex with the BV16 Fab fragment. The epitope occupies approximately 10% of the molecular surface area of Bet v 1 and is clearly conformational. A synthetic peptide representing a sequential motif in the epitope (11 of 16 residues) did not inhibit the binding of mAb BV16 to Bet v 1, illustrating limitations in the use of peptides for B cell epitope characterization. The single amino acid substitution, Glu(45)-Ser, was introduced in the epitope and completely abolished the binding of mAb ...
An allergy is a state of over-reactivity or hypersensitivity of the immune system of a pet to a particular substance called an allergen. Most allergens are proteins. The allergen protein may be of insect, plant or animal origin. Initial exposure of the dog, or more likely multiple exposures, to the allergen may over-sensitize the immune system, such that a subsequent exposure to the same or related allergen causes an over-reaction. This means that the immune response, which normally protects the dog against infection and disease, can be harmful. The actual immune reactions involved in allergies are quite complex. Most reactions involve an antibody in the blood called Immunoglobulin E (IgE). In an allergic reaction the allergen protein molecules combine with IgE antibody molecules and attach to a type of cell called mast cells, found in many tissues. When these cells are attached to the allergen, they break up and release potent chemicals such as histamines, which cause local inflammation. This ...
The National Asthma Education and Prevention Program Expert Panel guidelines for the management of asthma recommend that patients who require daily asthma medications have allergy testing for perennial indoor allergens and that, when triggers are found, exposure to allergens and pollutants be controlled through avoidance and abatement. For patients whose symptoms are not controlled adequately with these interventions and who are candidates for immunotherapy, the guidelines recommend referral to an allergist. However, the data supporting these recommendations are not consistent. Although there is evidence that simple allergen avoidance measures are ineffective, there is good evidence for the effectiveness of a comprehensive approach based on known sensitization. Thus, allergen avoidance may include removal of pets, use of high-efficiency particulate air filtration and vacuum cleaners, use of allergen-impermeable mattress and pillow covers, cockroach extermination, smoking cessation, and measures to

As a chef, I have to duty at work to ensure customers are provided with wholesome, safe food to eat. At home, I follow the same procedures I do at work to cook for my family. One of the things as a chef you need to consider are allergens. By law restaurants, food manufacturers and suppliers in the UK must provide information about allergens to their customers. Allergens are ingredients which may affect the customer adversely. Even the very smallest traces of some of these products may be harmful. It can be very difficult to eliminate some of the ingredients listed below from your diet and if you are allergic you need to read product labels very carefully - for example, most vegetable stock cubes and bases will use celery or celery salt as an ingredient.. I cannot guarantee any of my recipes are free from any allergens as I dont know the provenance of anyones supplies, but I am going to flag up what ingredients I know to be allergens in the recipes on this blog, by placing pictures at the ...
Food Allergens are proteins in food that create an immune response insensitive individuals. Once ingested, food allergens can cause a number of reactions, ranging in severity from hives and itching to anaphylaxis. Food manufacturers can protect those with food allergies by clearly labelling their products with a list of ingredients. Testing for the presence of components ensures food manufacturers that an unlabelled and potentially dangerous ingredient did not make its way unintentionally into a product during manufacture.. ...

Greetings from San Diego. As I mentioned last week, Im currently attending the AAAAI annual meeting, which has been absolutely great so far. Its been a blast reconnecting with friends and collaborators from all over the country. In the spirit of the conference, I thought I should share the other presentation that I will be making on Monday, which is a poster entitled "Prediction of Tolerance to Food Allergens by the Allergen-Specific IgE/Total IgE Ratio". This is an important topic in my opinion because it begins to address a question that I hear all the time from parents in my clinic: "Will my kid grow out of his food allergy?". Heres the abstract ...

Together with our biotinylated HDM allergen products, this antibody can be used to quantify HDM allergen specific IgE antibodies in mouse serum using an ELISA method. The antibody can be coated on an ELISA plate and act as a capture antibody to immobilize serum IgE antibodies. In the next step biotinylated HDM allergens are added to facilitate the detection of HDM allergen specific antibodies of the IgE isotype. Using a reference serum or by comparing multiple sera the HDM allergen specific antibodies can be (relatively) quantified.. A perfect way for researchers, who are working on allergic asthma research with mouse models, to determine whether immunizations of mice with house dust mite (HDM) have been successful by looking at the amount of specific antibodies against HDM proteins in the serum of mice. For more information about biotinylation we have a page which describes the protocol for the biotinylation products and antibodies.. ...
