Related to gliadin: Glutenin

gliadin

 [gli´ah-din]
a protein in wheat that contains the toxic factor associated with celiac disease.

gli·a·din

(glī'ă-din),
A class of protein, separable from wheat and rye glutens; a member of the prolamins (proline-rich proteins), which are insoluble in water, absolute alcohol, and neutral solvents, but soluble in 50-90% alcohol.

gliadin

(glī′ə-dĭn)
n.
Any of several prolamin proteins present in wheat grains, and constituting a component of wheat gluten. Gliadins can cause celiac disease in susceptible individuals by inducing a destructive immune response in the small intestine.

gli·a·din

(glī'ă-din)
A class of protein, separable from wheat and rye glutens, which contains up to 40% l-glutamine; a member of the prolamins, which are insoluble in water, absolute alcohol, and neutral solvents, but soluble in 50-90% alcohol.

gliadin

One of the two main components of wheat protein and the one that contains the factor responsible for damaging the intestinal lining and causing COELIAC DISEASE.

The celiac disease diagnostic criteria include: positive serology (autoantibodies against TG2, EMA in the IgA and IgG class and against deamidated gliadin peptides) and typical histopathological findings (atrophy of the intestinal villi, accompanied by an increase in number of intraepithelial lymphocytes and crypt hypertrophy) [7].
Gliadin increases the expression of interleukin-15 by causing degradation in epithelial cells, whereas an increased expression of interleukin-15 activates intraepithelial lymphocytes.
Other allergens of lower and higher molecular weight including (35-38KDa) and [alpha], [beta], I, gliadins of 112.5KDa, 95KDa, 85.5KDa, 65KDa, 58KDa, 50KDa, 43KDa, 40KDa, 38.5KDa, 32KDa, 30KDa, 26KDa, 21.5KDa, 19.2KDa, 18KDa were also found as allergens by comparing with allergen database respectively (Figure 6).
Gliadin induces an increase in intestinal permeability and zonulin release by binding to the chemokine receptor CXCR3.
Recently, Kennard et al .[7] reported 132 adult WDEIA patients in 4 UK centers diagnosed based on a clinical history compatible with allergic reactions after wheat consumption and with positive omega-5 gliadin specific IgE without performing food exercise challenge test.

[31] reported gliadin particles with spherical morphology with a diameter of 200 nm, and agglomeration is present but the particles are distinguishable.
This technique is generally used for gliadin and elastin peptide nanoparticles.
Also, data from the previous studies demonstrated that certain gliadin peptides such as p31-p43 dos not bind to HLA-DQ2 or HLA-DQ8 [17, 34] but are able to induce an immune response through TLRs [17, 34, 35].
Frequent occurrence of non-specific gliadin antibodies in chronic liver disease.
CDED combines partial EN with a diet that strictly excludes animal fat, high sugar intake, gliadin, emulsifiers, and maltodextrin.
The others are albumin, globulin, and gliadin. Also, a wheat allergy triggers a response similar to other allergies you might have to pollen or animal dander, including swelling or irritation of the mouth or throat, hives or a skin rash, watery eyes, headache, and anaphylaxis (constricted airways that make breathing difficult).
