BACKGROUND Exposure of patients with atopic asthma to allergens produces a long term increase in exhaled nitric oxide (FENO), probably reflecting inducible NO synthase (NOS) expression. In contrast, bradykinin (BK) rapidly reduces FENO. It is unknown whether BK suppresses increased FENO production after allergen exposure in asthma, and whether it modulates FENO via NOS inhibition. METHODS Lev...
background: there are many therapeutic methods for allergic conditions. cpg oli-gonucleotides play a critical role in immunity via the augmentation of th1 and suppres-sion of th2 responses. objective: in the present study we aimed to estimate the effec-tiveness of intranasal administration of cpg odn plus chenopodium album allergen in allergic asthma compared with the administration of allergen...
Background: The hypersensitivity to cow’s milk allergens is the most common allergies in children at the first year of life. The specific IgE evaluation is one of the important methods in diagnosis of allergic disease. The aim of this study was development of a sensitive and credible procedure for detection of cow’s milk allergens specific IgE. Methods: The allergen discs...
Background and aim: The frequency of sensitization to contact allergens varies in different countries because of both genetic and, more importantly, allergen exposure variations. The objective is to determine the frequency of sensitization to contact allergens in Iranian patients with dermatitis.Materials and methods: Four hundreds and one patients with a clinical diagn...
Environmental allergen sources such as house dust mites contain proteases, which are frequently allergens themselves. Inhalation with the exogenous a model of protease allergen, papain, to airways evokes release and activation IL-33, promotes innate adaptive allergic airway inflammation Th2 sensitization in mice. Here, we examine whether epicutaneous (e.c.) vaccination antigens without activity...
Although it has been accepted that pulmonary exposure to diesel exhaust particles (DEP), representative constituents in particulate matter of mass median aerodynamic diameter < or 2.5 microm (PM(2.5)), exacerbates murine allergic asthma, the in vivo effects of DEP on their cellular events in the context of allergen-specific Th response have never been examined. The aim of this study is to eluci...
IgE-mediated allergy affects >25% of the population in industrialized countries. Repeated contact with the disease-eliciting allergens induces rises of allergen-specific IgE Abs and progression of the disease to more severe manifestations. Our study uses a type of vaccine that is based on genetically modified allergen derivatives to treat allergic patients. We developed hypoallergenic derivativ...
The immunological mechanisms explaining development of an allergy in some individuals and not in others remain incompletely understood. Insect bite hypersensitivity (IBH) is a common, seasonal, IgE-mediated, pruritic skin disorder that affects considerable proportions of horses of different breeds, which is caused by bites of the insect Culicoides obsoletus (C. obsoletus). We investigated the a...
BACKGROUND Immune responses in allergic diseases begin with allergen sensitization, which usually occurs in childhood. Allergen sensitization involves a complex interplay of genetic and environmental factors, and sensitization patterns may change with age. OBJECTIVE To determine the predictors of allergen sensitization in the first 3 years of life in the growing up in Singapore towards health...
