our aim in this study was to identify and characterize allergic proteins in cooked wolf herring fish. we heated the crude extract alternatively at 50, 60, 70, 80, 90, and 100°c for one hour and results were compared by sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-page). also, proteins were immunoblotted with fish-sensitive patients’ sera. the major allergenic proteins were ide...

In the developing endosperm of bread wheat (Triticum aestivum), seed storage proteins are produced on the rough endoplasmic reticulum (ER) and transported to protein bodies, specialized vacuoles for the storage of protein. The functionally important gluten proteins of wheat are transported by two distinct routes to the protein bodies where they are stored: vesicles that bud directly off the ER ...

somaclonal variation is one of the possible sources of variation in plant breeding. to evaluate the usefulness of somaclonal variation for creating variation in iranian cultivars of wheat, proteins, enzymes and chromosome number of regenerated and seed-produced plants of wheat (alamout, hyrmand and maroon) were studied. plantlets obtained from the immature embryos and seed culture were collecte...

Background: Subunit vaccines are appropriate vaccine candidates for the prevention of some infections. In this study, three immunogenic proteins of Mycobacterium tuberculosis, including HspX, Ppe44, and EsxV as a new construction, were expressed alone and as a fusion protein to develop a new vaccine candidate against tuberculosis infection. Methods: To make the fusion protein, the three genes ...

INTRODUCTION Gliadin proteins play a key role in the pathogenesis of celiac disease; however, as a screen for celiac disease, anti-gliadin antibody testing has been replaced by the more sensitive and specific serological assays for transglutaminase autoantibodies (TGAA). A new generation of anti-gliadin antibody assays has been developed to detect synthetic, deamidated homologous gliadin peptid...

The immunogenic potential of α-gliadin protein from two ancient wheats was studied with reference to coeliac disease. To this aim we investigated Graziella Ra® and Kamut® (the latter is considered an ancient relative of modern durum wheat) in comparison to four durum wheat accessions (Senatore Cappelli, Flaminio, Grazia and Svevo). ELISA and Western Blot analyses - carried out by two monoclonal...

Wheat bugs are widely distributed in various areas of Europe, Asia and North Africa. Species belonging to the genus Eurygaster and Aelia pierce wheat kernels affecting protein quality. The effects of these insects’ feeding activity have been studied mainly in bread wheat (Triticum aestivum L.). This study provides information on the degradation of prolamin proteins (glutenins and gliadins) of b...

We analyzed the autologous NK cell interaction with gliadin-presenting dendritic cells. Gliadin is the known Ag priming the celiac disease (CD) pathogenesis. We demonstrate that gliadin prevents immature dendritic cells (iDCs) elimination by NK cells. Furthermore, cooperation between human NK cells-iDCs and T cells increases IFN-gamma production of anti-gliadin immune response. Gliadin fraction...

the aim of the study was to describe the urinary electrophoretic pattern of dogs with heartworm disease.urine samples from 15 heartworm-infected and 15 healthy dogs were taken. urinary specific gravity, urinaryprotein concentration and the urine protein/creatinine (u p/c) ratio were determined. urine proteins werefractionated using sds-page. results showed statistically significant differences ...
