Opis:
Gluten, which is a protein found in wheat, can trigger some gastrointestinal diseases in people with genetic predisposition. Gluten related disorders include celiac disease (CD), wheat allergy, baker’s asthma and non-celiac gluten sensivity (NCGS). Approximately 1% of population suffers from celiac disease. It is believed, that the occurrence of the disease is determined by the interaction of genetic, immunological and environmental factors. The consequence of the inflammatory process is the atrophy of the intestinal villi. That results in impaired bowel motility, improper digestion and impaired absorption of substances contained in the diet. Wheat allergy occurs among people with a genetic predisposition to allergies. People with this disorder are sensitized to products containing gluten and every contact with this antigen leads to mast cell activation and the release of mediators of the allergic reaction - mainly histamine. They mainly affect the skin (urticaria, atopic eczema, angioedema), digestive system (nausea, vomiting, spasmic abdominal pain) and respiratory tract (asthma, allergic rhinitis). Baker’s asthma is an interesting and common allergic, occupational disorder related to inhalation of flour containing gluten. The main symptoms include: conjunctivitis, rhinitis, dermatitis, as well as work-related cough and dyspnea. First reports on non-celiac gluten sensitivity (NCGS) appeared in 1980. The diagnosis of non-celiac gluten sensitivity is based on the exclusion of celiac disease and food allergy in a patient who has symptoms induced by ingestion of gluten. The exact pathomechanism of this disease is still unknown. Interestingly, some researches doubt that this disorder is caused by gluten intake. All of the above-mentioned diseases have a similar spectrum of clinical symptoms, and as part of the treatment require an elimination diet with the exclusion of gluten. The aim of this study is to provide information on gluten-related diseases, taking into account their pathomechanism and clinical picture.

Opis:
Introduction and objective. Gluten proteins (gliadins and glutenins) are polymorphic wheat storage proteins of allergenic properties. Significant differences in chemical composition between both protein groups allow to expect highly specific immunological response of individual subunits and fractions in reactions with IgE sera of people allergic to wheat. The aim of these studies was to identify and characterize the most allergenic gluten proteins (GP) and nongluten proteins (NGP) occurred in two closely related wheat hybrid genotypes. Materials and method. 3xC and 3xN wheat hybrids, which differ strongly in regard of gliadin composition, were analyzed. Seven people manifesting different symptoms of wheat allergy donated sera for the experiment. The technique of immunoblotting after SDS-PAGE was used for identification of allergenic subunits and fractions among GP and NGP. Immunologically active protein bands were visualized by chemiluminescence. Results. Great variation of immunodetection spectra was observed. Results of immunoblotting showed LMW glutenins to be of highest, gliadins of medium, while NGP of lowest allergenicity for selected patients. The 43-kDa and 47-kDa LMW glutenin subunits, 40-kDa and 43-kDa γ-gliadin fractions and 49-kDa NGP can be considered as the most immunoreactive among all protein bands separated by SDS-PAGE. Conclusion. The observed differentiation of immunodetection spectra allows to model highly specific IgE-binding profiles of allergenic wheat proteins attributed to individual patients with symptoms of gluten intolerance. Highly immunoreactive subunits and fractions among GP and NGP were identified. The observed immunoreactivity of 49 kDa NGP is worth to emphasize, as it has never been reported as wheat allergenic protein before.
