Increased immunoglobulin G (IgG) response to dietary antigens can be associated with gastrointestinal dysfunction and autoimmunity. The underlying processes contributing to these adverse reactions remain largely unknown, and it is likely that genetic factors play a role. Here, we estimate heritability and attempt to localize genetic factors influencing IgG antibody levels against food-derived a...
Cow’s milk, egg, wheat, soy, peanut, and fish account for about 90% of the food allergies but there are considerable differences from one country to another. Milk allergy is among the best characterized food allergies, particularly in infants and small children. Only part of the children with early allergy to cow’s milk grow into shool-age with milk allergy but those that do often have severe s...
A strict gluten-free diet (GFD) is the only currently available therapeutic treatment for patients with celiac disease (CD). Traditionally, treatment with a GFD has excluded wheat, barley and rye, while the presence of oats is a subject of debate. The most-recent research indicates that some cultivars of oats can be a safe part of a GFD. In order to elucidate the toxicity of the prolamins from ...
Poly(A)+ RNA isolated from the developing wheat endosperm var. Chinese Spring, has been used as template for the construction of a cDNA library. Within the library, clones have been identified by in vitro translation of hybrid-selected mRNA which encode alpha/beta gliadin related sequences and gamma-gliadin related sequences. The DNA sequence of one such clone has been determined and it shows h...
Macromolecular absorption of gliadin, a wheat protein and alpha lactalbumin, a milk protein was evaluated in control and Escherichia coli enterotoxin (heat-stable, heat-labile, and both heat-stable and heat-labile enterotoxin) treated mice. The peak concentration of gliadin and lactalbumin was two hours and three hours after their ingestion, respectively. There was also a significant increase (...
The level of IgA antibodies to gluten and gliadin proteins found in grains and to casein found in milk, as well as the level of IgG to gluten and gliadin, have been examined in 23 girls with Rett syndrome and 53 controls. Highly statistically significant increases were found for the Rett population compared to the controls. The reason for this remains unknown, but because IgA antibodies reflect...
The disulfide bonds in γ-46 gliadin were identified: Cys 173 Cys 192 , Cys 212 Cys 291 , Cys 165 Cys 199 (or Cys 200 ), Cys 283 Cys 200 (or Cys 199 ). The disulfide-containing peptides were obtained by limited hydrolysis of the intact protein with chymotrypsin at an enzyme/substrate ratio of 1:1000 at 20°C for 22 h with subsequent digestion of disulfide-containing fragments with trypsin an...
BACKGROUND A number of neurological conditions have been reported to be associated with gluten sensitivity, including ataxia, peripheral neuropathy, epilepsy, and occasionally, chorea. The pathogenic role of anti-gliadin antibodies has been questioned, and pathophysiology remains controversial. CASE REPORT I report chorea in a patient with celiac disease, which responded to a gluten-restricte...
Neogen Corp. developed the Veratox R5 Gliadin test kit for the detection of gliadin based on the monoclonal antibody R5 developed by Enrique Mendez (1). The purpose of this study was to validate the method under the requirements of the AOAC Research Institute Performance Tested Method program. There are two AOAC Official Methods for gluten detection in foods, 991.19 and 2012.01 (2), both of whi...
