Food protein induced enterocolitis syndrome (FPIES) is a food-related non-IgE-mediated gastrointestinal hypersensitivity disorder. Atypical FPIES is characterized by the presence of specific IgE for the causative food. The guidelines suggested for diagnostic oral food challenge in pediatric patients affected by suspected FPIES are different from the ones for children with IgE-mediated food alle...
IgE is a central molecule in allergic disease. We have isolated cDNAs coding for the heavy and light chains of a murine mAb specific to human IgE and expressed a recombinant single-chain variable fragment (ScFv) derived thereof in Escherichia coli. The purified recombinant ScFv has a molecular mass of 28 kDa as measured by mass spectrometry and shows a beta-sheet fold as determined by circular ...
Murine monoclonal IgE interacts with B cells of BALB/c mouse spleen with greater efficiency in the presence of its specific antigen. Complexes of anti-DNP IgE and DNP-OVA not only resist elution from B lymphocytes by acid but have a substantially longer dissociation half-time when compared with monomeric IgE (440 vs. 8 min, respectively). Further, these IgE-antigen complexes induce Fc epsilon R...
M to 2.8 x 10'0/M, averaging 7.7 x 109/M. Unexpectedly, the total number of IgE receptors/basophil was closely related to the serum IgE level. (r8 = 0.92, P < 0.001). Thus, either there is genetic association between serum IgE and the number of basophil IgE receptors, or, more likely, the receptor number is modulated by the serum IgE concentration.
مقدمه : آسم و آلرژی یکی از شایع ترین بیماریهای کودکان می باشد. آسم سندرمی است که توسط انسداد مجاری هوایی مشخص می شود که منجر به علایمی چون ویزینگ و تنگی نفس می شود. هلیکوباکترپیلوری یک باسیل مارپیچی و گرم منفی می باشد که در معده انسان کلونیزه می شود. بنظر می رسد هلیکوباکترپیلوری کودک را در برابر ابتلا به آسم محافظت می کند. هدف بررسی حاضر مطالعه تأثیر آلودگی با هلیکوباکترپیلوری بر آسم کودکی می...
Elevated serum immunoglobulin (Ig)E is the hallmark of atopy, and contributes to asthma and bronchial hyperresponsiveness in atopic individuals. In contrast, the significance of IgE in nonallergic subjects is less clear. The aim of the present study is to clarify a potential association of IgE and asthma in absence of clinical allergy. To this purpose 1,219 consecutive patients of a pulmonary p...
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by intense polyclonal production of autoantibodies and circulating immune complexes. Some reports have associated SLE with a Th2 immune response and allergy. In the present study 21 female patients with SLE were investigated for total IgE and IgE antibodies to dust house aeroallergens by an automated enzyme-linked fluores...
