Rabbit antiidiotypic IgG directed against IgG F(ab')2 anti-tetanus toxoid (TT) antibodies ("idiotype") elicited a Prausnitz-Kustner reaction in normal skin sites sensitized 48 h earlier with the serum of the idiotype donor that contained IgE anti-TT antibodies. The serum moiety that caused the sensitization was heat sensitive (56 degrees C, 1 h), and was specifically removed by passage over imm...

asthma is a complex and multifactorial disorder. several studies have reported association between different hla- dqb1 and hla- drb1 alleles and allergic asthma. the aim of the present study was to investigate the association of hla-class ii alleles and haplotypes, with total serum ige and the results of the skin prick test in iranian children with allergic asthma. a total of 112 patients with ...

OBJECTIVES To evaluate the association between serum total IgE levels and disease severity in adult patients with persistent allergic asthma and to explore the main predictors of IgE levels. METHODS We performed a multicenter, retrospective, observational study including adult patients diagnosed ≥ 1 year previously with persistent allergic asthma who were positive to ≥ 1 allergen. Patients al...

BACKGROUND Seawater and freshwater shrimp are some of the most common causes of food allergy among children in Thailand. Tropomyosin has been reported as a major allergen for shrimp allergic populations around the world. Despite a high number of shrimp-allergic Thai children, however, it is unknown whether shrimp tropomyosin is a major cause of allergic reactions. OBJECTIVES To clone and char...

Objectives: Allergen-specific immunotherapy (AIT) has been considered the most effective treatment for IgE mediated allergies, especially respiratory allergies. Several biomarkers have developed to evaluate clinical efficacy of AIT, yet none them thoroughly validated. So our objective here is investigate usefulness periostin as a biomaker monitoring allergen immunotherapy. Materials and methods...

Immune and inflammatory responses mediated by cytokines, play important roles in the pathophysiology of asthma. These responses are associated with overexpression of Th2 cytokines such as IL-4 and IL-13. These two cytokines use common receptors for signaling that lead to identical immunological effects and regulation of the Th1/Th2 balance. The aim of this study was to determine whether patient...

Polarized human T helper (Th) cells play a key role in the network of the specific immune system compartments. Cell-mediated immune response depends on activation of Th1-type cells, typically producing and releasing interferon-gamma and interleukin-2, whereas activation of Th2-type cells and production of cytokines such as interleukin-4, -5, and -10 are involved in humoral immune response and t...

Background and Purpose: Although molds are regarded as the main fungal allergen sources, evidence indicates that spores of Basidiomycota including Agaricus bisporus (A. bisporus) can be also found at high concentrations in the environment and may cause as many respiratory allergies as molds. The aim of the present study was to evaluate specific immunoglobulin E (IgE) and immunoglobulin G (IgG) ...

Tissues containing Hodgkin's disease (HD) are frequently infiltrated by large numbers of eosinophils. Because eosinophils as well as Reed-Sternberg (RS) cells express membrane receptors (CD23) for IgE, this study was performed to determine if IgE is present in tissue sections of HD and to correlate the results, when possible, with serum IgE levels and the presence of interleukin-5 (IL-5) messen...

BACKGROUND Immunoglobulin E (IgE) is a central player in the allergic response, and raised total IgE levels are considered as an indicator of atopy or potential development of atopy. A recent genome-wide scan in a German population-based cohort of adults identified the gene encoding the alpha chain of the high affinity receptor for IgE (FCER1A) as a susceptibility locus influencing total serum ...
