Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Interleukin-8 receptor modulates IgE production and B-cell expansion and trafficking in allergen-induced pulmonary inflammation. (1/5385)

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.  (+info)

gp49B1 inhibits IgE-initiated mast cell activation through both immunoreceptor tyrosine-based inhibitory motifs, recruitment of src homology 2 domain-containing phosphatase-1, and suppression of early and late calcium mobilization. (2/5385)

We define by molecular, pharmacologic, and physiologic approaches the proximal mechanism by which the immunoglobulin superfamily member gp49B1 inhibits mast cell activation mediated by the high affinity Fc receptor for IgE (FcepsilonRI). In rat basophilic leukemia-2H3 cells expressing transfected mouse gp49B1, mutation of tyrosine to phenylalanine in either of the two immunoreceptor tyrosine-based inhibitory motifs of the gp49B1 cytoplasmic domain partially suppressed gp49B1-mediated inhibition of exocytosis, whereas mutation of both abolished inhibitory capacity. Sodium pervanadate elicited tyrosine phosphorylation of native gp49B1 and association of the tyrosine phosphatases src homology 2 domain-containing phosphatase-1 (SHP-1) and SHP-2 in mouse bone marrow-derived mast cells (mBMMCs). SHP-1 associated transiently with gp49B1 within 1 min after coligation of gp49B1 with cross-linked FcepsilonRI in mBMMCs. SHP-1-deficient mBMMCs exhibited a partial loss of gp49B1-mediated inhibition of FcepsilonRI-induced exocytosis at concentrations of IgE providing optimal exocytosis, revealing a central, but not exclusive, SHP-1 requirement in the counter-regulatory pathway. Coligation of gp49B1 with cross-linked FcepsilonRI on mBMMCs inhibited early release of calcium from intracellular stores and subsequent influx of extracellular calcium, consistent with SHP-1 participation. Because exocytosis is complete within 2 min in mBMMCs, our studies establish a role for SHP-1 in the initial counter-regulatory cellular responses whereby gp49B1 immunoreceptor tyrosine-based inhibition motifs rapidly transmit inhibition of FcepsilonRI-mediated exocytosis.  (+info)

Hyper-IgE syndrome with recurrent infections--an autosomal dominant multisystem disorder. (3/5385)

BACKGROUND: The hyper-IgE syndrome with recurrent infections is a rare immunodeficiency characterized by recurrent skin and pulmonary abscesses and extremely elevated levels of IgE in serum. Associated facial and skeletal features have been recognized, but their frequency is unknown, and the genetic basis of the hyper-IgE syndrome is poorly understood. METHODS: We studied 30 patients with the hyper-IgE syndrome and 70 of their relatives. We took histories, reviewed records, performed physical and dental examinations, took anthropometric measurements, and conducted laboratory studies. RESULTS: Nonimmunologic features of the hyper-IgE syndrome were present in all patients older than eight years. Seventy-two percent had the previously unrecognized feature of failure or delay of shedding of the primary teeth owing to lack of root resorption. Common findings among patients were recurrent fractures (in 57 percent of patients), hyperextensible joints (in 68 percent), and scoliosis (in 76 percent of patients 16 years of age or older). The classic triad of abscesses, pneumonia, and an elevated IgE level was identified in 77 percent of all patients and in 85 percent of those older than eight. In 6 of 23 adults (26 percent), IgE levels declined over time and came closer to or fell within the normal range. Autosomal dominant transmission of the hyper-IgE syndrome was found, but with variable expressivity. Of the 27 relatives at risk for inheriting the hyper-IgE syndrome, 10 were fully affected, 11 were unaffected, and 6 had combinations of mild immunologic, dental, and skeletal features of the hyper-IgE syndrome. CONCLUSIONS: The hyper-IgE syndrome is a multisystem disorder that affects the dentition, the skeleton, connective tissue, and the immune system. It is inherited as a single-locus autosomal dominant trait with variable expressivity.  (+info)

Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness. (4/5385)

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.  (+info)

Immunosurveillance of alglucerase enzyme therapy for Gaucher patients: induction of humoral tolerance in seroconverted patients after repeat administration. (5/5385)

Alglucerase, a macrophage-targeted enzyme replacement therapy for Gaucher disease, has been successfully used for several years to improve clinical symptoms and reverse disease progression. As part of an immunosurveillance program, 1,122 Gaucher patients were monitored for antibody response to glucocerebrosidase, the active component of alglucerase. Seroconversion was detected in 142 patients (12.8%) by enzyme-linked immunosorbent assay (ELISA) and confirmed by radioimmunoprecipitation. The majority (75%) of the seroconverted population had no detectable levels of circulating inhibitory antibody as assessed by in vitro inhibition of enzymatic activity of the therapeutic molecule. Of the remaining patients with putative inhibitory antibodies, the majority had only low levels of serum inhibitory activity, which was transient. A very small number of patients were identified as developing true neutralizing antibodies, as defined by the development of antibodies that impacted clinical efficacy. Many of the patient antibody responses were also diminished with time. Eighty-two of the 142 seroconverted patients have stopped producing antibody to the molecule and appear tolerized. The mean time for humoral tolerization was 28 months from initiation of therapy. Of 64 seroconverted patients followed for at least 30 months of therapy, the tolerization rate was 93%. These results show that although 12.8% of the patients on therapy developed antibodies to the molecule, 90% of these patients became tolerized over time.  (+info)

Involvement of tachykinin receptors in sensitisation to cow's milk proteins in guinea pigs. (6/5385)

BACKGROUND: There is growing evidence for a pivotal role for tachykinins in gut neuroimmune interactions. AIMS: To determine whether NK1, NK2, and NK3 tachykinin receptors are involved in milk protein induced allergic sensitisation. METHODS: Eight groups of 12 Dunkin-Hartley guinea pigs (250-300 g) were used. Four groups were sensitised to milk proteins for three weeks. During this period, these animals were injected intraperitoneally each day with NK1 (SR 140333; 0.3 mg/kg), NK2 (SR 48968; 5 mg/kg), or NK3 (SR 142801; 5 mg/kg) receptor antagonist or vehicle. The fifth group had water available instead of milk and was used as a non-sensitised control. The three other groups received the NK receptor antagonists for three weeks but were not sensitised to milk proteins. RESULTS: Sensitised animals treated with NK1 and NK3 receptor antagonists had both lower IgE and IgG serum titres, evaluated by passive cutaneous anaphylaxis, and lower specific IgG serum titres, determined by enzyme linked immunosorbent assay (ELISA), than vehicle treated animals. Sensitisation induced an increase in intestinal mast cell number which was abolished by treatment with the NK1 receptor antagonist. Antigenic challenge-induced jejunal hypersecretion was also blocked by treatment with the NK1 receptor antagonist. CONCLUSION: In guinea pigs, NK1 and NK3 but not NK2 receptors are involved in sensitisation to cow's milk. However, NK1 but not NK3 receptor antagonists abolish both the hypermastocytosis induced by food allergy and the hypersecretion induced by antigenic challenge, suggesting different roles for NK1 and NK3 receptors in the mechanisms of sensitisation to beta-lactoglobulin.  (+info)

Induction of Ig somatic hypermutation and class switching in a human monoclonal IgM+ IgD+ B cell line in vitro: definition of the requirements and modalities of hypermutation. (7/5385)

Partly because of the lack of a suitable in vitro model, the trigger(s) and the mechanism(s) of somatic hypermutation in Ig genes are largely unknown. We have analyzed the hypermutation potential of human CL-01 lymphocytes, our monoclonal model of germinal center B cell differentiation. These cells are surface IgM+ IgD+ and, in the absence of T cells, switch to IgG, IgA, and IgE in response to CD40:CD40 ligand engagement and exposure to appropriate cytokines. We show here that CL-01 cells can be induced to effectively mutate the expressed VHDJH-C mu, VHDJH-C delta, VHDJH-C gamma, VHDJH-C alpha, VHDJH-C epsilon, and V lambda J lambda-C lambda transcripts before and after Ig class switching in a stepwise fashion. In these cells, induction of somatic mutations required cross-linking of the surface receptor for Ag and T cell contact through CD40:CD40 ligand and CD80: CD28 coengagement. The induced mutations showed intrinsic features of Ig V(D)J hypermutation in that they comprised 110 base substitutions (97 in the heavy chain and 13 in the lambda-chain) and only 2 deletions and targeted V(D)J, virtually sparing CH and C lambda. These mutations were more abundant in secondary VHDJH-C gamma than primary VHDJH-C mu transcripts and in V(D)J-C than V lambda J lambda-C lambda transcripts. These mutations were also associated with coding DNA strand polarity and showed an overall rate of 2.42 x 10(-4) base changes/cell division in VHDJH-CH transcripts. Transitions were favored over transversions, and G nucleotides were preferentially targeted, mainly in the context of AG dinucleotides. Thus, in CL-01 cells, Ig somatic hypermutation is readily inducible by stimuli different from those required for class switching and displays discrete base substitution modalities.  (+info)

Evidence for the involvement of IgE-basophil system in acute serum sickness. (8/5385)

The role of the basophils in acute serum sickness of rabbits was examined by monitoring daily the absolute number of basophils before, during and after the disease period. After antigen (bovine serum albumin, BSA) elimination, levels of serum IgE and in vitro basophil degranulation in the presence of BSA were determined. The results showed that the onset of glomerular lesions depends upon the simultaneous occurrence of circulating immune complexes greater than 19 S and of an in vivo basophil depletion--probably equivalent to degranulation--reaching 70% of the pre-disease number. Post-disease antigen-dependent in vitro degranulation of the basophils and levels of serum IgE anti BSA did not prove to be good indexes of basophil sensitization. Our data suggest that basophils are instrumental at early stages of the deposition of immune complexes, most probably through their sensitization by membrane-bound IgE antibodies.  (+info)

Methods: This was a case-control study involving 25 asymptomatic contact lens wearers, 25 patients with type 1 allergic conjunctivitis, and 25 age- and sex-matched healthy controls. Total serum immunoglobulin E levels were detected by enzyme-linked immunosorbent assay. Serum-specific IgE analysis against the listed indoor, food, and outdoor allergens were studied by immunofluorescence assay for participants whose total serum immunoglobulin E levels were ,100 IU/mL. Pearsons and Spearmans correlations were used for bivariate analysis. Statistical significance was accepted at the 0.05 level ...

Effect of vitamin E (alpha-tocopheryl acetate and alpha-tocopheryl nicotinate) on IgE antibody formation in mice was investgiated . Female BALB/c mice were immunized with dinitrophenylated ascaris protein (DNP-As) and aluminium hydroxide gel (alum). Supplementation of vitamin E in diets or oral administration of vitamin E mixed with sesame oil resulted in a suppression of IgE antibody formation. On the contrary to IgE antibody formation, IgM or IgG (hemagglutinin; HA) formation was significantly enhanced. These results indicate that vitamin E is capable of suppressing IgE antibody formation and enhancing non-IgE antibody formation. ...

An allergen-specific immunoglobulin E (IgE) blood test is done to check whether a person is allergic to a particular substance.. An allergic reaction occurs when the immune system overreacts to something, often in the environment, thats harmless to most people. To protect the body from this perceived threat, or allergen, the immune system of an allergic person produces antibodies called immunoglobulin E.. IgE antibodies are found mostly in the lungs, skin, and mucous membranes. They cause mast cells (a type of cell involved in the bodys immune response) to release chemicals, including histamine, into the bloodstream. Its these chemicals that bring on many of the allergy symptoms that affect a persons eyes, nose, throat, lungs, skin, or gastrointestinal tract.. Because IgE antibodies are unique to each allergen (for example, IgE produced in response to pollen differs from IgE produced after a bee sting), checking for specific variants in the blood can help determine if an allergy is ...
In this study altered immune response as measured by total serum IgE level among symptomatic HIV infected patients, asymptomatic HIV positive individuals and healthy controls with and without helminths co-infection and the impact of deworming and/or ART on these immune activation was assessed within defined groups of population from tropical settings of Ethiopia where both HIV and helminths infections are common. Consistent with the earlier suggestions [25-27] that Africans generally present with elevated total serum IgE levels and our previous observations [14-16], patients in this study also showed a high total serum IgE level as shown by more than three-folds of the total IgE above the reference ranges irrespective of HIV and helminths co-infections. The highly significant correlation between helminth egg intensity and serum IgE level may partly explain the elevated total serum IgE levels observed in sub-Saharan regions, where heavy helminthic infections are widespread [14-16, 25-27]. It ...
Background: Dry eye disease (DED) is a multifactorial disease of the tears and ocular surface. No epidemiologic reports have yet been published about the relationship between DED and allergic rhinitis or sensitization to allergens. Objective: To investigate the association between DED and allergic conditions in the general adult Korean population. Methods: This population-based cross-sectional study included 17,542 individuals (ages ,= 19 years) who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) from 2010 to 2012. Data for total serum immunoglobulin E (IgE) and allergen-specific IgE levels were available for 1857 subjects. Data were analyzed by using logistic regression to determine the association of DED with allergy or allergic conditions, including allergic rhinitis, atopic dermatitis, asthma, increased total serum IgE, and sensitization to house-dust mite (Dermatophagoides farinae), dog, and cockroach allergens. Results: The prevalence of DED, allergic ...
Nitric oxide, a relatively stable free radical, is increased in exhaled air and plasma of people with asthma compared with that in healthy individuals, and is increasingly implicated in the pathogenesis of inflammation in asthma.8,25 Nitric oxide produced in the lungs is an important regulator of airway events, including modifying airway tone, regulating pulmonary vascular tone, stimulating mucin secretion, modulating mucociliary clearance through effects on ciliary beat frequency, and immune surveillance including tumoricidal and bactericidal effects.26 Studies of NOS in asthma have been focused on iNOS as iNOS was shown to be up regulated in patients with asthma and is believed to represent the major source of nitric oxide in the lungs.27 NOS2A (iNOS) has been identified as a calcium-independent isoform, which was detected in the brain, lungs, and liver of rats after endotoxin treatment.28 The transcriptional activation of iNOS in these cells is regulated by endogeneous mediators (such as ...

Background: Pediatric bronchial asthma is associated with considerable morbidity. The study was carried out to examine the association of Human Leukocyte Antigen (HLA)- Class II with the disease as we found no similar study on Asian Indian population. Objective: To define the HLA-Class II antigens in Asian Indian pediatric patients with asthma. Methods: A total of 103 children with asthma and 152 controls were analysed for HLA Class II (DRB1, DQB1and DPB1) by PCR-SSP (Sequence Specific Primers) method. Total serum IgE levels were determined by ELISA assay. Results: A positive family history was recorded in 59 patients (57%) and 13 (8.5%) of healthy controls. Serum IgE levels were more than normal range in 72% of the patients and 33% of healthy subjects with mean values of 4877 and 627 IU/ml, respectively. DRB1*04 and DQB1*03 showed significant positive relations while DRB1*15 showed a negative association with asthma. DQB1*02 was more common in healthy individuals but was not statistically significant.
It has been suggested that neutrophils may be involved in the late-phase reaction of immunoglobulin E (IgE)-dependent hypersensitivity states. However, the identity of neutrophil-associated molecules inducing the release of mediators remains unclear. In this report, we demonstrate that human neutrophils from normal donors or from patients with inflammatory disorders could bind myeloma IgE proteins, especially after desialylation. Northern blot, immunoprecipitation, and flow cytometry analyses revealed that neutrophils did not express Fc epsilon RII/CD23, but rather Mac-2/epsilon binding protein (BP), belonging to the S-type lectin family. Similarly to IgA used as positive control, myeloma IgE proteins, as well as polyclonal IgE antibodies with or without antibody specificity, were both capable of inducing a neutrophil respiratory burst. Anti-Mac-2 but not anti-CD23 mAb strongly decreased the IgE-dependent activation of neutrophils, induced either by the specific antigen or by anti-IgE ...
Selective suppression of IgE antibody response was demonstrated. Preadministration of DNP-coupled mycobacterium (DNP-Tbc) inhibited the formation of anti-DNP IgE antibody induced by DNP-OA without any suppressive effect on anti-DNP IgG antibody response. Secondary anti-DNP IgE antibody response by DNP-OA was also significantly depressed by the preadministration of DNP-Tbc. Anti-OA IgE antibody response induced by DNP-OA was also depressed by DNP-Tbc, whereas anti-OA IgE antibody response induced by PAB-OA was not affected by the preadministration of DNP-Tbc. Preimmunization with DNP-MGG induced much higher anti-DNP IgG antibody response than DNP-Tbc, but DNP-MGG did not suppress the induction of anti-DNP IgE antibody. The transfer of DNP-Tbc-primed spleen cells into normal mice depressed anti-DNP IgE antibody response. B cell-depleted cell populations also showed a comparable inhibitory effect to that of unfractionated DNP-Tbc primed cells. In the adoptive cell transfer experiment, ...
CCDs (cross-reactive carbohydrate determinants) are carbohydrate side chains inducing the production of specific IgE antibodies. A Type I allergy is caused by the formation of specific IgE antibodies against allergens. Most allergens are proteins. In eucaryotic organisms, many proteins are subjected to post-translational glycosylation and therefore carry carbohydrate side chains. Specific IgE antibodies are produced by the immune system against the real allergens but also against carbohydrate side chains of allergens (anti-CCD IgE) of plant origin, of insects, of molluscs and of latex. The anti-CCD IgE also leads to cross-reactions with unrelated proteins and therefore are called cross-reactive carbohydrate determinants (CCD).. CCDs do not cause allergic symptoms. Approximately 25 % of allergic patients produce anti-CCD IgEs, which, however, do not trigger allergic symptoms and therefore most likely have no clinical relevance. This low clinical significance was thought to be due to low binding ...
OBJECTIVE: The goal was to examine the relationship between age at the introduction of solid foods during the first year of life and allergic sensitization in 5-year-old children.. METHODS: We analyzed data from the Finnish Type 1 Diabetes Prediction and Prevention nutrition study, a prospective, birth cohort study. We studied 994 children with HLA-conferred susceptibility to type 1 diabetes mellitus for whom information on breastfeeding, age at the introduction of solid foods, and allergen-specific immunoglobulin E levels at 5 years was available. The association between age at the introduction of solid foods and allergic sensitization was analyzed by using logistic regression.. RESULTS: The median duration of exclusive breastfeeding was 1.8 months (range: 0-10 months). After adjustment for potential confounders, late introduction of potatoes (,4 months), oats (,5 months), rye (,7 months), wheat (,6 months), meat (,5.5 months), fish (,8.2 months), and eggs (,10.5 months) was significantly ...
Allergic asthma is characterized by airway hyperresponsiveness to specific and non-specific stimuli with elevated serum IgE levels and eosinophilic inflammation. It is well known that allergen-specific CD4 + type 2, T-helper (Th2) cells and immunoglobulin E (IgE)-sensitized mast cells are key players in the allergic response. Therefore, therapeutic strategies that induce regulatory T cells (Tregs) to suppress Th2-cell responses and inhibit IgE-mediated activation on mast cells seem to have the greatest potential to efficiently inhibit allergen-induced disorders. Short-chain fatty acids (SCFAs) have anti-inflammatory and immuno-suppressive properties and are considered especially good candidates for the role. Actually, our preliminary results showed that SCFA-phenylbutyrate (PB) induced tolerogenic dendritic cells, enhanced the generation of splenic Foxp3 + Tregs and inhibited mast cell degranulation. PB also expressed a preventive effect in an ovalbumin-induced asthmatic animal model. Therefore, ...

RESULTS. The median patient age was 8.2 years (range, 5.7-11.3 years), and the median 1-second forced expiratory volume was 95% of the predicted value. The median absolute eosinophil count in the peripheral blood was 0.48 x 109 /L and the ratio of total serum immunoglobulin E to the age-adjusted upper limit of the normal range was 2.7. Atopy, as defined by at least one positive response to skin prick testing, was found in 170 (83.3%) of the 204 patients. House dust mites were the most commonly sensitised aero-allergen (n=167; 81.9%). Sensitisation to food allergens was found in 47 (23.0%) of the patients. The self-reported frequency of asthmatic attacks was associated with a positive response to skin prick testing with animal allergens (P for trend = 0.001), whereas spirometric indices correlated with the degree of atopy and the presence of in vivo cockroach-specific immunoglobulin E ...

Suppression of IgE replies is a major goal for immunotherapy, especially in the field of allergy. even when they are not given until after starting HgCl2 administration. IFN- is definitely a pivotal cytokine in ameliorating the Th2 response and actions aimed at selective up-regulation of this cytokine may be of restorative value in suppression of undesirable IgE reactions. < 005 was taken to indicate statistical significance. RESULTS Exogenous type-1 cytokines suppress IgE production in HgCl2-treated BN rats HgCl2 treatment of BN rats resulted in designated elevation of serum IgE concentrations, as previously reported [7]. IgE levels were barely above normal at day time 7, then rose rapidly to maximum levels by day time 14. Administration of exogenous recombinant rat IFN- at a dose of 6 104 U/day time Motesanib had little effect (= 069, two-tailed MannCWhitney = 0009 HgCl2 only, = 001 group treated with 6 104 U/day time; two-tailed MannCWhitney = 0026). IgE levels at day time 14 were ...
The property of 109 CD4+ T cell clones (TCC) to induce IgE synthesis in vitro in human B cells was compared with their ability to produce IL-2, IL-4, and IFN-gamma in their supernatants (SUP) after 24-h stimulation with PHA. A significant positive correlation was found between the property of TCC to induce or enhance spontaneous IgE synthesis and their ability to release IL-4. In contrast, there was an inverse relationship between the IgE helper activity of TCC and their ability to release IFN-gamma, whereas no statistical correlation between the property to induce IgE synthesis and to produce IL-2 was observed. The ability of PHA-SUP from 71 CD4+ TCC to induce IgE synthesis in B cells was also investigated. Twenty-nine SUP (all derived from TCC active on IgE synthesis) induced production of substantial amounts of IgE in target B cells. There was a correlation between the amount of IgE synthesized by B cells in response to these SUP and their IL-4 content. An even higher correlation was found ...

Atopic diseases like asthma, atopic dermatitis and allergic rhinitis are complex traits of multifactorial origin. This study aimed to reveal gene-gene- and gene-environmental interactions of eight polymorphisms in five candidate genes. We examined whether 6 genetic variants of the genes coding for Interleukin-4 (IL-4), Interleukin-13 (IL-13) and their common receptor unit IL4R-alpha had genotypic effects on atopy-related traits such as total serum IgE levels in a large German birth cohort study (Multicenter Atopy Study, MAS 90) with longitudinally well defined phenotypes. Two single nucelotide polymorphisms (SNP) in the IL-13 gene (Arg130Gln, C-1055T) showed a significant association with increased serum IgE levels over the whole period of seven years. In addition, exposure to maternal smoking appears to modify the above effects on total serum IgE levels. We tested the association of atopy-related traits and a SNP of the complement factor 5 receptor (-245T) in the MAS cohort and in an ...
The effect of rat immunoglobulins and immune complexes on the locomotor function of rat polymorphonuclear leukocytes (PMN) was investigated in vitro. Rat immunoglobulin G1 (IgG1), IgG2a, IgG2b, and IgA monoclonal antibodies specific for the dinitrophenyl hapten were used. Both monomeric and polymeric IgA showed chemotactic activity in a dose-dependent manner. IgG1 and IgG2b also induced a dose-dependent locomotor response of PMN, but the nature of the induced migration was chemokinetic (enhancing random migration). IgG2a was chemotactic and induced maximal migration at a relatively low concentration. IgG1- and IgG2b-immune complexes induced stronger migration than antibody alone; however, IgA- and IgG2a-immune complexes did not. IgA was shown to modify the chemotactic movement of PMN induced by N-formylmethionyl-leucyl-phenylalanine (FMLP). In the presence of both IgA and FMLP in the lower chamber, the migration towards suboptimal concentrations of FMLP was enhanced. By contrast, IgA in the ...
Crystallographic and solution studies have shown that IgE molecules are acutely bent in their Fc region. cross-linking by allergen leads to cell degranulation, release of inflammatory mediators and an immediate allergic response. Disruption of the IgE-FcRI conversation is usually a validated strategy for therapeutic intervention in allergic diseases including asthma: an anti-IgE monoclonal IgG antibody, omalizumab (Xolair?, Novartis Pharmaceuticals Ltd), inhibits IgE binding to FcRI and is effective in the Tarafenacin treatment of severe persistent asthma and other allergic diseases2. IgE consists of a dimer of two identical heavy and two identical light chains, but unlike IgG in which the antigen-binding Fab region is separated from the receptor-binding Fc region by a flexible hinge, IgE contains an additional disulphide-linked pair of domains, (C2)2, forming a (C2-C3-C4)2 dimer1. Fluorescence depolarisation studies to assess segmental flexibility have shown IgE to be less flexible than IgG3-6, ...

Allergic asthma may be associated with elevated IgE levels. Treatment for allergic asthma may include anti-IgE medications in addition to inhalers.
The main normal function of IgE (Immunoglobulin E) is believed to be in the protection against parasitic infestation. However, IgE is also associated with allergy and allergen-specific IgE antibodies may trigger allergic reactions in the presence of the proper allergen. IgE is normally found in low amounts in serum/plasma but is significantly increased in allergic individuals and the detection of allergen-specific IgE serves as the basis for many in vitro assays for specific diagnosis of allergy.. ...
COMMON DYSREGULATION AMONG ALLERGIC CONDITIONS. Allergic asthma, allergic rhinitis and atopic dermatitis are prevalent allergic diseases. These diseases can be distinguished by the location of their most important symptoms; lungs, sinuses and skin respectively.. They also share many characteristics, including the same underlying immune system dysregulation as evidenced by inappropriate T-cell mediated responses to innocuous antigens, peripheral eosinophilia, elevated serum IgE levels, chronic immune system activation, and over-production of inflammatory mediators, including leukotrienes, cytokines and chemokines.. LEUKOTRIENES AND INFLAMMATION IN ALLERGIC DISEASES. Leukotrienes are eicosanoid lipid mediators and are derived from the essential fatty acid arachidonic acid (AA), which is concentrated in the membrane phospholipids of cells of the immune system. The role of inflammatory mediators (leukotrienes) in allergic diseases is well characterized. In particular, leukotrienes play a significant ...
Anti-IgE antibodies react with the IgE isotype of human immunoglobulins. IgE is the shortest-lived immunoglobulin with a half-life of two days in serum. IgE plays an important role in allergy. It is especially associated with type 1 hypersensitivity, where IgE shows high-affinity binding to Fc receptors expressed on the surface of mast cells. Antigen binding to Fc receptor-bound IgE upon re-exposure to specific allergens results in degranulation and the release of a variety of mediators, such as histamine and cytokines. IgE has two main receptors: the high-affinity receptor FcεRI, which is expressed only on mast cells and basophils, and the low-affinity receptor FcεRII (CD23), which is expressed on B cells. - Belgique
Back in the Dark Ages, allergic people were probably much more likely to fight off intestinal parasites, viral and bacterial infections and even scourges like the Black Death. Up to 100 years ago, in fact, carrying genes that elicited a high IgE (Immunoglobulin E) response, was probably a distinct evolutionary advantage, something that kept the carriers of these genes more apt to survive to reproduce.. In our modern times, though, atopic individuals (those prone to allergies) find themselves fighting their own bodies or other otherwise harmless substances like peanuts, eggs, milk, nuts, fish, animal dander, dust, mould, grasses, pollens. Simple things can sometimes kill an allergic person. Those prone to allergies are often depicted as weak, mouth-breathing, nerdy, canary types whom others delight in kicking sand in their faces.. I come from a long line of allergic types. My grandfather on my fathers side died of an asthma attack in 1926. My father is anaphylactic to flat fish. My sister is ...
Background: To investigate the associations between clinical obstetric factors during birth and doctor-diagnosed wheezing and allergic sensitization during early childhood.. Methods: We followed 410 Finnish women from late pregnancy until 18 months age of their children. All children were delivered at term. Doctor-diagnosed wheezing among children was established by questionnaires, while specific immunoglobulin E antibodies to inhalant and food allergens were measured in 388 children at 1 year of age. Data on maternal obstetric variables were recorded at the time of delivery.. Results: Children of mothers with longer duration of ruptured fetal membranes before birth had significantly higher risk of doctor-diagnosed wheezing during early childhood compared to those children with shorter period of ruptured fetal membranes (III vs I quartile; aOR 6.65, 95% CI 1.99-22.18; P , 0.002 and IV vs I quartile; aOR 3.88, 95% CI 1.05-14.36, P , 0.043).

The immunoglobulin E (IgE) blood test is often done as part of an initial screen for allergies. High IgE levels also may indicate a parasitic infection.
Genetic polymorphisms of IL-18 and its receptor were reported to be associated with elevated serum IgE levels, atopy, and/or asthma. However, conflicting results were observed in various association studies and functional activity of these polymorphisms remains unclear. A total of 393 unrelated subjects were involved in this study. Direct PCR-sequencing method was used to screen novel polymorphisms. The functional significance of these polymorphisms was investigated using reporter gene assay. Three known (-137, +113, and +127) polymorphisms in the IL-18 promoter were identified with a perfect linkage disequilibrium (Δ = 1, p , 0.001) among them. No significant difference in the genotype frequencies of these polymorphisms between atopy and atopic phenotypes in Singaporean Chinese, Malays, and Indians was observed. However, transcriptional activities were significantly increased in HepG2 cultured cells with wild-type IL-18 genotype (-137/G, +113/T, and +127/C) than mutated genotype (-137/C, ...
Why the immune system mounts an attack against seemingly harmless agents baffles researchers. Because the immune system treats the harmless agent as a threat, B lymphocytes produce immunoglobulin E antibody (IgE). IgE attaches to mast cells such as those present in the nasal and bronchial passages, resulting in histamine release. Inflammation and allergy symptoms follow. Once sensitized, mast cells automatically release histamine when the invading agent reappears. Because IgE can sensitize cells anywhere in the body, individuals symptoms vary (eg, a cat may produce hives in one person and generate sneezing in another person).9,11 Allergy should not be confused with atopy. Atopy indicates that a person has developed a symptomless sensitization. The Increase in Allergies A genetic susceptibility to allergens has been established, but a shift in the human gene pool is an unlikely explanation for the increased prevalence of allergies. Shifts in population-based traits require several generations to ...
The purpose of this study was to evaluate the role of two major allergic pathways - IgE and non-IgE antibody mediated food allergy reaction (FAR) and lung inflammation disease using crustacean extracts. Although IgE antibody mediated food allergy reaction (IFAR) are defined as major mechanism in the past several decades, proteases from different sources acting similar to allergens as well as the long-term inflammatory stimulus through activation of protease activation receptors (PARs) are important. This opens new insight into non-IgE antibody mediated food allergy (NFAR) due to its dual effects. Therefore, it is necessary to investigate the interactions of these two pathways for a better understanding of the currently poor correlation between clinical symptoms and IgE specific diagnostics.. The current studies employed a humanized rat basophilic leukemia (RBL) cell line as well as a human lung epithelial cell line (A549) due to the presence of IgE receptors and PARs. Flow cytometric (FACS) and ...
Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to something in the environment that usually causes little or no problem in most people. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, a runny nose, shortness of breath, or swelling. Food intolerances and food poisoning are separate conditions.. Common allergens include pollen and certain food. Metals and other substances may also cause problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the bodys immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. Diagnosis is typically based on a ...
When food proteins are injected in to the blood stream, a type I hypersensitivity reaction against an allergen, encountered for the first time, causes a response in a type of immune cell called a TH2 lymphocyte, which belongs to a subset of T cells that produce a cytokine called interleukin-4 (IL-4). These TH2 cells interact with other lymphocytes called B cells, whose role is the production of antibodies. Coupled with signals provided by IL-4, this interaction stimulates the B cell to begin production of a large amount of a particular type of antibody known as IgE that are specific to the food proteins. Secreted IgE circulates in the blood and binds to an IgE-specific receptor (a kind of Fc receptor called FcεRI) on the surface of other kinds of immune cells called mast cells and basophils, which are both involved in the acute inflammatory response. The IgE-coated cells, at this stage are sensitized to the allergen (food proteins). [1] [2] ...
Asthma is a common chronic disease worldwide and affects approximately 24 million persons in the United States. It is the most common chronic disease in childhood, affecting an estimated 7 million children.

Eczema can also increase your total IGE levels potentially affecting your blood test results. While it is not common, there have been cases where some individuals with extremely high scores to an allergen are not actually allergic. The high scores are due to high total IGE levels related in part to extreme eczema.. If you think you might not be allergic to an allergen or have accidentally ingested an allergen without reaction-you should discuss this with your allergist.. ...

THURSDAY, July 6, 2017 (HealthDay News) - Identification of allergens by immunoglobulin E (IgE) testing improves outcomes in atopic dermatitis, according to a study published online June 20 in the International Journal of Dermatology.. Brett M. Will, from Georgetown University in Washington, D.C., and colleagues retrospectively assessed affected body surface area at first presentation, IgE quantitative assaying of allergens (IgEQAA) classes, and total IgE concentration for 54 patients with atopic dermatitis.. The researchers found that 41 of 54 patients had an abnormally high total IgE concentration (76 percent). After making lifestyle changes, nine (17 percent) of these patients showed significant improvement in their symptoms.. While IgEQAA has historically been used by allergists, it has yet to see the same widespread usage within the field of dermatology. IgEQAA is easy to perform compared to skin prick testing and may be helpful in some patients who are not responding to conservative ...
Non-steroidal anti-inflammatory drugs (NSAIDs) are associated with type I hypersensitivity, including cutaneous manifestations (e.g., urticaria and angioedema), respiratory manifestations (rhinitis, nasal polyposis, asthma), and anaphylaxis. To assess the sensitivity/specificity of in vitro tests for verifying the causative/tolerant drugs and cross-reactivity of different NSAIDs, we used three assays, including two ELISA tests for histamine/leukotriene C4 (LTC4) release, and a flow cytometric basophil activation test (BAT). We recruited 82 patients with NSAIDs-induced type I hypersensitivity (angioedema of the most cases), and isolated the peripheral leukocytes to perform histamine/LTC4 release tests in 38 patients, and BAT in 44 patients. The cell response to NSAIDs was examined in the incubation containing suspected or tolerant drugs with concentrations equal to 1-fold (physical level) or 10-fold Cmax. Comparing with the data of solve controls of the same subject, positive response was ...
Canine atopic dermatitis (CAD) is an allergic skin disease associated with IgE and IgG antibodies (Ab) to environmental allergens. The aim of this study was to determine which other factors influence serum Ab levels in CAD-affected and non-affected dogs as this has only been poorly investigated in dogs so far. Total and allergen-specific IgE levels and Dermatophagoides farinae (DF)-specific IgG1 and IgG4 were measured by ELISA in sera of 145 CAD-affected and 271 non-affected Labrador- and Golden retrievers. A multivariable logistic regression analysis including the factors age, breed, gender, castration, clinical CAD status and allergen-specific immunotherapy (ASIT) was performed. Golden retrievers had more frequently total (OR=1.87, 95% CI=1.26-2.87, p,0.01) and specific IgE levels above the threshold value than Labrador retrievers, suggesting that genetic factors influence IgE levels in dogs. Castration was generally associated with low Ab levels (OR=0.43-0.65, p,0.05). Surprisingly, dogs with ...
Specific IgE to gliadin was proposed as a marker for wheat dependent exercise induced anaphylaxis, while Tri a 14 was found to induce IgE response in bakers asthma. We evaluated whether these components could be used for discriminating phenotypes of wheat allergy. Twenty-nine patients who were wheat-induced anaphylaxis and/or urticaria (n=21, group I) and bakers asthma (n=8, group II) were enrolled. The prevalence of serum specific IgE to Tri a 14 was higher in group II (25%) than in group I (4.8%), while the serum specific IgE to gliadin was significantly higher in group I (70%) than in group II (12.5%). The cutoff value for predicting the bakers asthma using the ratio of serum specific IgE to Tri a 14 to gliadin was 742.8 optical density×1,000/(kU/L) with high sensitivity and specificity. These findings suggest that Tri a 14/gliadin may be a potential marker for predicting bakers asthma.

In a study of 14 subjects with respiratory symptoms associated with exposure to live fish bait, skin- and serum-specific IgE tests with Lucilia caesar, Galleria mellonella, and Tenebrio molitor extracts were conducted. Thirteen subjects had asthma, all 14 had rhinoconjunctivitis, and 3 had contact urticaria. Eleven subjects had respiratory symptoms after fishing with live bait, and 3 subjects had symptoms during their work in a commercial fish bait farm. The presence of skin- or serum-specific IgE to L. caesar extract was demonstrated in 13 subjects, to G. mellonella extract in 4 subjects, and to T. molitor extract in 3 subjects. After exposure to live fish bait, 2 subjects had an early asthmatic response, 3 had a late asthmatic response, and 2 had no asthmatic response. Late asthmatic response was associated with a long-lasting increase in bronchial responsiveness (8 ...
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.. ...
BACKGROUND In addition to helminthic infections, elevated serum IgE levels were observed in many protozoal infections, while their contribution during immune response to these pathogens remained unclear. As IgE/antigen immune complexes (IgE-IC) bind to human cells through FcεRI or FcεRII/CD23 surface molecules, the present study aimed to identify which functional receptor may be involved in IgE-IC interaction with human macrophages, the major effector cell during parasite infection. METHODOLOGY/PRINCIPAL FINDINGS Human monocyte-derived macrophages were infected with Toxoplasma gondii before being incubated with IgE-IC. IgE receptors were then identified using appropriate blocking antibodies. The activation of cells and parasiticidal activity were evaluated by mediator quantification and direct counting of infected macrophages. RNAs were extracted and cell supernatants were also collected for their content in tumor necrosis factor (TNF)-α, interleukin-10 (IL-10) and nitrites. Sera from symptomatic
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. ...
Food allergy is defined as an adverse immunological response to food. Some of the tests discussed in this chapter not only aid in the diagnosis of food allergies, but also are useful in monitoring the natural history of patients' food allergies over time, from diagnosis to oral tolerance. Once food allergy has been identified as the likely cause of symptoms, confirmation of the diagnosis and identification of the implicated food(s) can begin. There are a number of tools that aid in the diagnosis of food allergy, some of which are more commonly used, and they vary in their ability to provide an accurate diagnosis. Available studies include in vivo tests such as skin prick and intradermal testing, oral food challenges (OFCs), elimination diets, and patch testing and in vitro tests such as quantification of food-specific IgE and basophil histamine release (BHR). Tests that have not proven helpful in food allergy diagnosis include quantification of food-specific IgG, total serum IgE levels, ...

Mast cells play a central role in the pathogenesis of allergic reaction. Activation of mast cells by antigens is strictly dependent on the influx of extracellular calcium that involves a complex interaction between signalling molecules located within the cells. We have previously reported that tHGA, an active compound originally isolated from a local shrub known as Melicope ptelefolia, prevented IgE-mediated mast cell activation and passive systemic anaphylaxis by suppressing the release of interleukin-4 (IL-4) and tumour necrosis factor (TNF)-α from activated rat basophilic leukaemia (RBL)-2H3 cells. However, the mechanism of action (MOA) as well as the molecular target underlying the mast cell stabilising effect of tHGA has not been previously investigated. In this study, DNP-IgE-sensitised RBL-2H3 cells were pre-treated with tHGA before challenged with DNP-BSA. To dissect the MOA of tHGA in IgE-mediated mast cell activation, the effect of tHGA on the transcription of IL-4 and TNF-α mRNA was ...

Background Two conditions are utilized as markers of atopy: the current presence of circulating anti-allergen IgE antibodies and the presence of positive skin prick test (SPT) reactions to allergenic extracts. groups although a few individuals in the SPT unfavorable group experienced markedly high IgE levels (Physique ?(Figure2A).2A). The α-… Cross-reactivity of IgE antibodies with B. tropicalis and A. lumbricoides antigens Sera from SPT-positive and SPT-negative individuals were pre-incubated with increasing amounts of AlE before assayed for α-BtE IgE or total IgE levels. Overall more reduction in Elvitegravir α-BtE IgE levels was found in the unfavorable SPT group than in the positive SPT group in all AlE concentrations. (Physique ?(Figure5A).5A). A plateau of reduction was reached when the sera were incubated with 30 μg/mL of AlE: larger concentrations of this extract did not lead to lower binding of the α-BtE IgE to the solid-phase BtE (data not shown). However only with the lowest ...
A new study estimates that 2.5 percent of the United States population, or about 7.6 million Americans, have food allergies. Food allergy rates were found to be higher for children, non-Hispanic blacks, and males, according to the researchers. The odds of male black children having food allergies were 4.4 times higher than others in the general population.. The research, which was funded by the National Institutes of Health and appears in the Journal of Allergy and Clinical Immunology, is the first to use a nationally representative sample, as well as specific immunoglobulin E (IgE) or antibody levels to quantify allergic sensitization to common foods, including peanuts, milk, eggs, and shrimp. The hallmark of food allergy is production of IgE antibodies to a specific food protein. Once IgE antibody is made, further exposure to the food triggers an allergic response. IgE levels are often high in people with allergies.. This study is very comprehensive in its scope. It is the first study to use ...

IgE-mediated food allergy constitutes an important and increasing health issue with significant morbidity and mortality. Although double blind placebo controlled food challenges remain the gold standard for correct diagnosis, the technique has not entered mainstream use for obvious ethical, practical and economic reasons. Therefore, in clinical practice most physicians rely upon quantification of specific immunoglobulin E (sIgE) antibodies and skin tests to confirm their clinical suspicion. However, diagnosis of food allergy is not always straightforward, as these in vivo and in vitro tests are not absolutely predictive for the clinical outcome. In other words, these tests frequently hamper correct diagnosis of food allergy as they fail to discriminate between patients with genuine overt food allergy and individuals who are merely sensitized, viz. have a positive test result but have no food-related symptoms. Moreover, difficulties are compounded as sensitization profiles might display ...

Type 1 (Immediate Onset) IgE-Mediated Food Allergy IgE-mediated food reactions are immediate in onset and usually involve symptoms such as abdominal cramping, diarrhoea, skin rashes, hives, swelling, wheezing or the most extreme reaction, anaphylaxis. When provoked by a recognised food antigen, IgE antibodies promote mast cell degranulation and the release of histamine and other inflammatory mediators.. Type 3 (Delayed Onset) IgG-Mediated Food Sensitivity IgG-mediated food reactions (also referred to as food sensitivity, food intolerance) are more subtle in their presentation, often occurring hours to days after exposure to food antigens. Unlike IgE-mediated food reactions, IgG-mediated food reactions produce symptoms which are cumulative in nature. Instead of attaching to mast cells, like the IgE antibodies, IgG antibodies bind directly to food as it enters the bloodstream forming circulating immune complexes.. Delayed food reactions may affect any organ or tissue in the body. Common conditions ...
Interleukin-10 (IL-10) is certainly a major regulatory cytokine of inflammatory responses that is considered to play an important role in specific immunotherapy. the B-cell proliferation, IgE synthesis and plasma cell differentiation enhanced by IL-10. IL-10 enhances B-cell IgE production by promoting differentiation into plasma cells. CD27/CD70 interactions under IL-10 and sufficient CD40 cosignalling exert the opposite effect on IgE synthesis. The results of this study indicate that precautions are crucial when planning immunotherapy using IL-10 in IgE-related allergic diseases. Cowan strain- (SAC-) and CD40-activated human B cells is usually synergistic [18,19]. However, the functions of IL-10 in B-cell IgE synthesis are under controversy still. The addition of IL-10 to purified B cells activated by soluble IL-4 and CD154 inhibits IgE synthesis [17]. Other evidence signifies that IL-10 promotes IgE synthesis in the current presence of IL-4 and anti-CD40 moAb cross-linked with Compact ...
TY - JOUR. T1 - Serum IgE studies in atopic dermatitis. AU - Clendenning, W. E.. AU - Clack, W. E.. AU - Ogawa, M.. AU - Ishizaka, K.. PY - 1973. Y1 - 1973. N2 - To determine whether serum IgE levels in patients with atopic dermatitis bear a relationship to the severity and course of the dermatitis, serum levels were measured over several months in 24 patients. Excluded were patients with concurrent rhinitis or asthma, or those receiving therapy (hyposensitization, systemic corticosteroids) which might have affected serum levels. A clinical profile was developed to gauge the severity and extent of the dermatitis during the course of the study. The results show that many patients with atopic dermatitis have normal serum IgE levels. No significant fluctuation of serum IgE levels in individual patients was noted during the course of the study even though the dermatitis varied in severity. However, there was a positive relationship of significance (p,.05) between overall severity of the dermatitis ...
Each of the three classes of biomarkers evaluated here proved to be associated with variations in patient survival. To limit the number of possible false-positive associations, we used P , 0.001 for statistical significance criterion to account for the numbers of markers and comparisons tested.. Serologic IgE measurements. We observed the typical mortality profile for the deadly glioblastoma histology with nearly 65% of our study subjects deceased within 12 months of diagnosis. However, none of the 13 patients with elevated IgE succumbed during this same time. The very longest survivors (e.g., ,40 months) were persons with high IgE, and they lived on average 9 months longer than those with normal or borderline levels. This suggests that those with higher IgE levels might have either better antitumor defenses or less aggressive tumors with weaker anti-immunologic effects. Given that half as many glioblastoma patients have elevated IgEs as normal population controls (11% versus 23%, respectively; ...
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.. ...
TY - JOUR. T1 - Sensitization profiles of a case of pollen-food allergy syndrome. AU - Sano, Akiyo. AU - Yagami, Akiko. AU - Inaba, Yasuko. AU - Yamakita, Takashi. AU - Suzuki, Kayoko. AU - Matsunaga, Kayoko. PY - 2011/1/1. Y1 - 2011/1/1. N2 - A 13-year-old girl who had had pollinosis since the age of eight began to experience itching of the ears and vomiting after eating fresh fruits such as peach, apple and watermelon. This occurred at 10 years of age. The girl displayed positive reactions to six kinds of pollens, eleven kinds of fruits, numerous vegetables and to recombinant: rBet v2 present in specific IgE antibodies. She also reacted positively to several pollens, fruits and rBet v2 in the skin prick test. In the component-resolved diagnosis (CRD) using microarray technology, she also tested positive for profilin, a pan-allergen among plants. It is reported that profilin cross-reacts between pollen, fruits, vegetables and latex. From these results, we concluded that the allergic reactions ...

Allergic Sensitization - There is an acute response (early stages) and a late-phase response (later stages). In the early stages, the Antigen-Presenting Cell causes a response in a TH2 lymphocyte which produce the cytokine interleukin-4 (IL-4). The TH2 lymphocytes interact with B cells and together they produce IgE. IgE circulates around and binds to receptors of cells leading to an acute inflammatory response.[13] In this case, sensitization is commonly referring to commencement of allergic responses.[14] Allergic sensitization development varies with age, with younger children at the greatest risk of developing allergic sensitization.[15] There are a variety of tests to diagnose allergic conditions. Tests that are commonly used place potential allergens on the skin of the patient and looking for a reaction to look for an allergen-specific IgE (Immunoglobulin E). They have shown that IgE levels are at their greatest before 10 years of age and fall vastly until one reaches 30.[15] There is a ...

Elevated serum tIgE levels can be detected in subjects sensitized to allergens as well as non-allergic diseases. Serum tIgE levels are shown to be associated and significantly higher in atopic disorders as allergic rhinitis, extrinsic asthma and atopic dermatitis than age-adjusted, healthy (nontoxic) population [11,18,19]. Serum tIgE levels are also shown to be significantly increased in parasitic infections, especially helminthes infection thus people living in helminthes endemic areas have significantly higher levels of tIgE despite being non-atopic and most of these IgE are nonspecific thus limiting its use as an allergic marker [20,21]. Extreme elevations of tIgE concentrations are observed in myeloma that selectively produce IgE par protein called IgE myeloma, hyper IgE syndrome (Joe syndrome) and some disorders of vacuities, although these conditions are rare but should be considered in the differential diagnosis if significantly elevated tIgE levels are observed [22].. A recent study ...
Study Population. Ninety-nine children from age 2 months to 16 years who presented to the Pediatric Emergency Room of the University of Virginia and received treatment for acute wheezing, were enrolled in this study. Fifty-seven control patients were enrolled from the same setting who did not previously or currently manifest wheezing/respiratory symptoms.. Method. Serum for immunoglobulin E (IgE) and radioallergosorbent test (RAST) IgE for D. Pteronyssinus/Farinae, cat epithelium, short ragweed, rye grass, and mixed Cockroach was collected. Nasal saline washes were obtained for respiratory syncytial virus (RSV) antigen detection and respiratory viral cultures. Nasal smears for eosinopils were obtained as well as saliva samples for the nicotine metabolite, cotinine.. Results. IgE RAST testing identified an increasing number of study patients with IgE specific antibodies. Nasal smears revealed similar but not identical findings. Patients over 2 years of age demonstrated a family history of atopy, ...
Allergen immunotherapy is effective in patients with IgE-dependent allergic rhinitis and asthma. When immunotherapy is given continuously for 3 years, there is persistent clinical benefit for several years after its discontinuation. This disease-modifying effect is both antigen-specific and antigen-driven. Clinical improvement is accompanied by decreases in numbers of effector cells in target organs, including mast cells, basophils, eosinophils, and type 2 innate lymphoid cells. Immunotherapy results in the production of blocking IgG/IgG4 antibodies that can inhibit IgE-dependent activation mediated through both high-affinity IgE receptors (FcεRI) on mast cells and basophils and low-affinity IgE receptors (FcεRII) on B cells ...
Anaphylaxis is a severe, life-threatening, systemic allergic reaction that is almost always unanticipated and may lead to death by airway obstruction or vascular collapse. Anaphylaxis occurs as the result of an allergen response, usually immunoglobulin E-mediated, which leads to mast cell and basophil activation and a combination of dermatologic, respiratory, cardiovascular, gastrointestinal, and neurologic symptoms. Dermatologic and respiratory symptoms are most common, occurring in 90 and 70 percent of episodes, respectively. The three most common triggers are food, insect stings, and medications. The diagnosis of anaphylaxis is typically made when symptoms occur within one hour of exposure to a specific antigen. Confirmatory testing using serum histamine and tryptase levels is difficult, because blood samples must be drawn with strict time considerations. Allergen skin testing and in vitro assay for serum immunoglobulin E of specific allergens do not reliably predict who will develop anaphylaxis.
Nineteen patients, 6 to 17 years of age, completed treatment: 12 in the active group and 7 in the placebo group. One dropped out because of persistent eczema during dose escalation. Baseline median milk IgE levels in the active (n = 13) versus placebo (n = 7) groups were 34.8 kUa/L (range, 4.86-314 kUa/L) versus 14.6 kUa/L (range, 0.93-133.4 kUa/L). The median milk threshold dose in both groups was 40 mg at the baseline challenge. After OIT, the median cumulative dose inducing a reaction in the active treatment group was 5140 mg (range 2540-8140 mg), whereas all patients in the placebo group reacted at 40 mg (P = .0003). Among 2437 active OIT doses versus 1193 placebo doses, there were 1107 (45.4%) versus 134 (11.2%) total reactions, with local symptoms being most common. Milk-specific IgE levels did not change significantly in either group. Milk IgG levels increased significantly in the active treatment group, with a predominant milk IgG4 level increase.. ...

Dr. Bettina Wagner. The term allergy is commonly used to refer to several types of diseases that are caused by different forms of hypersensitivity reactions. Hypersensitivity immune responses directed against harmless antigens subsequently causing damage to host tissues. Depending on the immune mechanisms involved, hypersensitivity reactions are clustered in four types (I-IV). Type I hypersensitivities are mediated by a particular class of antibody known as Immunoglobulin E, or IgE. We will use the term allergy in this proposal to refer to type I hypersensitivities.. In the horse, only a few epidemiological studies about allergy exist in selected breeds. This reflects in our opinion the current difficulties to diagnose allergy rather than its absence. Most allergies are diagnosed by clinical signs only. The most common diagnostic test to identify allergic responses is intradermal skin testing with allergens, which is, however, mainly performed in larger clinics or universities, but rare in ...
Your immune systems primary goal is to keep your body healthy. In the case of food allergies, your immune system mistakes harmless food proteins as a threat and attack. Large amounts of immunoglobulin E (IgE), an antibody, are produced. IgE causes the release of histamine and other chemicals, which can trigger the symptoms of an allergic reaction. While any food has the potential to cause an allergic reaction, there are eight foods that account for almost 90 percent of all food allergies: peanuts, tree nuts, milk, eggs, soy, wheat, fish and shellfish. Food allergies can be diagnosed through a blood test. A blood test is used to measure the amount of allergen-specific IgE antibodies present in the blood. If blood testing is negative, an oral food challenge can also be performed in order to rule out a food allergy. This test takes place in the clinic where you will be under constant medical supervision. This ensures if you experience an allergic reaction it can be treated immediately. The food in ...

Detect possible allergic responses to various substances in the environment (see Test Includes) 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. ...

Mouse IgG and IgA, with reactivity to dinitrophenol conjugated to carrier protein, have been isolated from myeloma proteins by means of a variety of affinity techniques. The IgA was predominantly in the dimeric form. The in vitro and in vivo biological activities of IgA-containing immune complexes were assessed in the rat. IgA-containing immune complexes were demonstrated, in a dose-dependent manner in vitro, to activate neutrophils and to generate O.-2. In addition, these immune complexes showed evidence of complement activation in vitro, by the use of immunofixation techniques. When IgA was instilled into the airways of rats and antigen was injected intravenously, acute lung injury occurred, as reflected by increases in lung permeability and morphological changes consisting of blebbing of endothelial cells, intra-alveolar hemorrhage, and fibrin deposition. The lung changes were directly proportional to the amount of IgA instilled into the airways and failed to occur if intravenous injection of ...

  • Immunoglobulin A (IgA), in its secretory form, is the main effector of the mucosal immune system and provides an important first line of defense against most pathogens that invade the body at a mucosal surface [1] . (
  • Predicted to enable antigen binding activity and immunoglobulin receptor binding activity. (
  • This study was aimed at defining molecular species of prostate-specific antigen (PSA) in immune complexes with immunoglobulin M (IgM). (
  • B-cell immunity is mediated by the immunoglobulins and is commonly referred to as humoral immunity. (
  • Secretory IgA, a major immunoglobulin in most bovine external secretions. (
  • The aim of this study is to compute the budget impact of adopting Kiovig, a new ready-to-use 10% liquid immunoglobulin preparation, as a treatment for primary immunodeficiency from the perspective of the Belgian health care payer. (
  • The analysis compared the "world with Kiovig" to the "world without Kiovig" and calculated how a change in the mix of immunoglobulins used to treat primary immunodeficiency would impact drug spending during 2010-2014. (
  • The aim of this treatment is to replace immunoglobulin to maintain normal Immunoglobulin G (IgG) levels, with the dose used individualised for each patient. (

  • I, like many other with ME, were given immunoglobulin injections as an experimental treatment for our disease. (
  • Immunoglobulin oligomers may prove to be targets for the treatment of PCNA. (
  • A high A/G ratio suggests underproduction of immunoglobulins (as may be seen in some genetic deficiencies and in some leukemias). (
  • Process that minimizes or prevents immunoglobulin-associated adverse reactions. (
  • 2002. Multiple functions of immunoglobulin A in mucosal defense against viruses: an in vitro measles virus model. (
  • The most abundant class of immunoglobulins in the blood is IgG (73%), which has a molecular weight of 150 kd. (
  • The best line of defense against invading pathogens in the newborn dairy calf is the immunoglobulins from colostrum that are absorbed in the small intestine. (
  • BACKGROUND: Immunoglobulin rearrangement involves random and imprecise processes that act to both create and constrain diversity. (
  • Although a large number of clinical trials have demonstrated that immunoglobulin is effective and well tolerated, various adverse effects have been reported. (
  • In this paper, we reviewed the incidence, risk factors, clinical manifestations of and preventive measures for adverse effects related to immunoglobulin. (
  • Adequate supplies of alternative intravenous immunoglobulin solution products are available for clinical use in Australia, and it is not anticipated that this recall will lead to any shortage of supply in the foreseeable future. (
  • This repertoire of immunoglobulins is crucial for the newborns who are very sensitive to infections, especially within the respiratory and digestive systems. (
  • It is the most common type of immunoglobulin in newborns and, and her partner did not use condoms. (
  • to review and describe the management of primary maternal CMV infections using CMV hyper immunoglobulin (CMVIG) and the outcome of the newborns and update the international experience. (
  • The first is excessive TSH receptor stimulation, and an example is Graves' disease, which is an autoimmune condition where thyroid stimulating immunoglobulins, or TSIs, bind to the TSH receptor and stimulate excess hormone production. (
  • MF provided and validated data on immunoglobulin use in VITT. (
  • Recent media reports have described access issues regarding immunoglobulin (Ig) therapies relied on by people living with primary immunodeficiencies. (
  • Finally, by the same rule, B cells must first release M then G immunoglobulin on primary exposure. (
  • CMV hyper immunoglobulin (CMVIG) was used as prophylaxis in pregnant women diagnosed with primary CMV in early pregnancy, before amniocentesis. (
  • The amyloid deposits are found in the dermis and subcutis, and they contain clonal immunoglobulin light chains, produced by a local proliferation of plasma cells. (
