Background The FAST project (Food Allergy Specific ImmunoTherapy) aims at the development of safe and effective treatment of food allergies. Classical allergen-specific immunotherapy (SIT) for treatment of food allergy using subcutaneous injections with food extracts has proven to be effective but too dangerous due to anaphylactic side-effects. FAST aims at developing a safe alternative by repl...

Fusarium species are among airborne fungi and recognized as causative agents of human atopic disorders. However, Fusarium allergens have not been well characterized and the lack of information limits clinical diagnosis and treatment of fungal allergy. The purpose of this study is to identify and characterize important allergens of F. proliferatum. IgE-reacting F. proliferatum components were id...

Diverse therapeutic strategies for food allergy are under investigation including food allergen-specific and nonspecific approaches. Allergen-specific approaches include immunotherapy with native food allergens, immunotherapy with mutated recombinant allergens, and diets containing extensively heated milk or egg. Native allergen immunotherapy can be administered via oral, sublingual, subcutaneo...

An allergen cloned from a Blattella germanica (German cockroach) cDNA library, encoded a 182-amino acid protein of 20,904 Da. This protein, designated B. germanica allergen 4 (Bla g 4), was expressed as a glutathione S-transferase fusion protein in Escherichia coli and purified by affinity chromatography and high-performance liquid chromatography. The prevalence of serum IgE antibody to recombi...

Recombinant DNA technology is a common procedure to produce allergenic proteins in vitro. To date, more than 40 food allergens from fruits, vegetables, nuts, milk and seafood have been expressed as recombinant proteins. Since recombinant proteins can be produced in large quantities and in controlled quality, they promise to be suitable tools for precise diagnostics and research applications. "H...

Dog allergy is common worldwide. However, the allergenicity of dog allergy is still unclear in China as well as in special group, such as children. In this study, we chose Can f 6, a major dog allergen which belongs to the lipocalin to study its allergenicity in Chinese dog allergic children. Can f 6 gene was subcloned into pET-28a vector and transformed into E. coli BL21 (DE3) cells for expres...

BACKGROUND S100A7 is an antimicrobial peptide involved in several inflammatory diseases. The aim of the present study was to explore the expression and regulation of S100A7 in seasonal allergic rhinitis (SAR). METHODS Nasal lavage (NAL) fluid was obtained from healthy controls before and after lipopolysaccharide (LPS) provocation, from SAR patients before and after allergen challenge, and fro...

Published by Elsevier B.V Asthma is a frequent, disabling chronic disease which is characterized by respiratory symptoms (wheeze, breathlessness, chest tightness and cough) and chronic airway inflammation. It affects more than 300 million people world-wide and represents a heavy economic burden to health care systems (Ka...

BACKGROUND Current diagnostics for allergies, such as skin prick and radioallergosorbent tests, do not allow for inexpensive, high-throughput screening of patients. Additionally, extracts used in these methods are made from washed pollen that lacks pollen surface materials that may contain allergens. METHODOLOGY/PRINCIPAL FINDINGS We sought to develop a high-throughput assay to rapidly measur...
