objective(s):sublingual allergen-specific immunotherapy is a safe and effective method for treatment of ige-mediated respiratory allergies; however, the underlying mechanisms are not fully understood. this study was planned to test whether sublingual immunotherapy (slit) can exert epigenetic mechanisms through which the airway allergic responses can be extinguished. materials and methods:balb/c...

Recombinant lactic-acid bacteria (LAB) are able to inhibit allergen-specific T-cell responses. In this study, we examined whether oral feeding of recombinant LAB was able to suppress allergen-induced airway inflammation and hyperreactivity (AHR) in a murine model. Animals were intraperitoneally sensitized with Dermatophagoides pteronyssinus group-5 allergen (Der p 5) and orally treated with rec...

BACKGROUND Natural allergen sources can supply large quantities of authentic allergen mixtures for use as immunotherapeutics. However, such extracts are complex, difficult to define, vary from batch to batch, which may lead to unpredictable efficacy and/or unacceptable levels of side effects. The use of recombinant expression systems for allergen production can alleviate some of these issues. S...

Background The current tools available for diagnosing food allergy include the clinical history, trial elimination diets, diet diaries, skin prick testing (SPT) and allergen-specific serum IgE testing. Since 15 years, development of allergen-based microarrays using recombinant/natural proteins is increasing, resulting in commercially available microarrays to detect specific IgE against more tha...

Among the most frequent anaphylactic reactions to insects are those attributed to reduviid bugs. We report the purification and identification of the major salivary allergen of these insects. This 20-kDa protein (procalin) is a member of the lipocalin family, which includes salivary allergens from other invertebrates and mammals. An expression system capable of producing reagent quantities of r...

Allergen-specific immunotherapy (AIT) is an allergen-specific treatment for people with IgE-related allergies. used to treat allergic disorders when symptoms persist despite medication and allergen avoidance. The therapy presumed effective if it reduces the use of medications, improves quality life even after discontinuation treatment, as well prevents conversion one type allergy other developm...

Severe and life-threatening side effects can occur in patients receiving allergen-specific immunotherapy (SIT), and recombinant allergens made from cDNA have been used in clinical trials for ten years and appear promising for SIT. The aim of this study is to explore the effects of the recombinant allergen Der f 2 (the group 2 allergen from Dermatophagoides farinae) on the neuro-endocrino-immune...
