background: decay of vaccine–induced antibody titres without boosting of the wild measles virus has been well documented. revaccination against measles has reduced the prevalence of the disease worldwide. revaccination may cause ige induced anaphylaxis. objective: to study measles igg antibody in revaccinated populations and its relation to ige induced hypersensitivity. methods: blood samples w...

BACKGROUND Elevated serum immunoglobulin (Ig) E is a diagnostic marker of immediate-type allergic reactions. We hypothesize that serum IgE does not necessarily reflect total body IgE because in vivo IgE can be bound to cell surface receptors such as FcepsilonRI and FcepsilonRII (CD23). The aim of this study was to analyze the relationships between levels of serum IgE, cell-bound IgE, and IgE-re...

hyper ige syndrome (hies) is a rare primary immunodeficiency disease. most of hies cases are sporadic. hies type ad is caused by mutation in signal transducer and activator of transcription-3 (stat-3). a number of mosaicism hies has been reported that is associated with intermediate phenotype. autosomal recessive hies (ar-hies) is due to mutation in dock-8 or cytokine sis 8 and tyk2 or tyrosine...

Food allergy is a significant public health problem with limited treatment options. As Allergy Herbal Formula 2 (FAHF-2) showed potential for food treatment, we further developed purified version named EBF2 and identified active compounds. We investigated the mechanisms of on IgE-mediated peanut (PN) its compound, berberine, IgE production.

BACKGROUND Sensitization to Anisakis spp. can produce allergic reactions after eating raw or undercooked parasitized fish. Specific IgE is detected long after the onset of symptoms, but the changes in specific IgE levels over a long follow-up period are unknown; furthermore, the influence of Anisakis spp. allergen exposure through consumption of fishery products is also unknown. OBJECTIVE To ...

We have investigated expression of an IgE-binding factor (IgE-BF) cDNA in both COS-7 monkey kidney cells and Chinese hamster ovary cells. Transient expression of the IgE-BF clone in either cell type yielded IgE-BF, which potentiated an in vitro IgE response and had an affinity for lentil lectin. In contrast, when the transient expression experiments were carried out in the presence of tunicamyc...

BACKGROUND The positive and negative predictive values of specific IgE to penicillins are not well established for penicillin hypersensitivity. One reason may be that serum IgE levels to penicillin diminish over time. The objective in this study was to investigate variations in serum half-life (T½) for specific IgE to penicillins (s-IgE) and to evaluate the outcome of penicillin challenges in p...

BACKGROUND IgE-expressing (IgE+ ) plasma cells (PCs) provide a continuous source of allergen-specific IgE that is central to allergic responses. The extreme sparsity of IgE+ cells in vivo has confined their study almost entirely to mouse models. OBJECTIVE To characterize the development pathway of human IgE+ PCs and to determine the ontogeny of human IgE+ PCs. METHODS To generate human IgE+...

Induction of IgE class-restricted tolerance was studied in high IgE-responder (BALB/c X SJL)F1 mice, of which the parental BALB/c and SJL mice are high and low IgE-responder mice, respectively. 2,4-Dinitrophenyl (DNP)-specific monoclonal IgE was administered to (BALB/c X SJL)F1 mice neonatally in two forms: soluble IgE at 250 micrograms per injection, or 10-100 ng of IgE coupled to 25-50 X 10(6...

serum ige assay is a mainstay step in the allergy work up. allergenic extracts and molecular components are available at present. this real life study compared the serum specific ige levels against allergenic extracts with allergenic molecules in patients allergic to parietaria, betulaceae , and mites. this retrospective real life study included 489 subjects with respiratory allergy. inclusion ...
