Current testing for Gluten-Reactivity and (CD) includes serum IgG and IgA against gliadin and
tissue transglutaminase-2 (tTG2). These antibodies are measured against minor components of a
wheat protein called alpha-gliadin. However, as noted above, wheat consists of multiple proteins
and peptides including, alpha-gliadin, alpha-beta-gliadin, omega-gliadin, low- and high-molecular
weight glutenins, gluteomorphin, prodynorphin, farinin, serpin, amylases, globulins, albumins,
agglutinins and more. Any of these antigens has a capacity to challenge the immune system.
Because of this heterogeneity of gluten proteins and peptides, multiple variations in T-cell
responses may occur against them. Recent medical research indicates that a large number of
gluten epitopes, may be implicated in the development of Gluten-Reactivity, CD and other
associated conditions such as NCWR.
Why, if there are several proteins in wheat, do we assess reactivity to only one? The repertoire
and hierarchy of gluten peptides stimulate the intestinal T-cells and results in a significant
elevation of IgG and IgA production. Publications regarding T cell reactions stimulated our
concept for the development of the original Array 3 – Wheat/Gluten Proteome Reactivity and
Autoimmunity (launched in 2011).
Comprehensive quantitative mapping of T-cell epitopes was determined in CD.17 Results
demonstrated that patients respond to a heterogeneous array of peptides; some recognized many
peptides from single or multiple gliadin families, while others reacted to only one peptide. These
results confirmed that a large number of gluten epitopes may be implicated in the development of
CD and associated diseases. Indeed, a T-cell line from one Celiac patient failed to recognize any
of the 21 tested peptides, which confirmed that a large number of gluten and other wheat protein
epitopes are implicated in development of CD and associated disorders. This suggests that other
gliadin peptides and proteins are involved in the pathogenesis of Gluten-Reactivity and CD.
We extended this heterogeneity in T-cell responses to gluten and other proteins or peptides
originated from wheat to humoral immune responses by measuring IgG and IgA antibodies
against multiple wheat antigens and peptides as well as enzymes associated with wheat/gluten
autoimmunities. Heterogeneity in IgG and IgA antibodies against these antigens was confirmed
by variation in antibody response against different wheat associated antigens on individual basis.
Research, performed by Aristo Vojdani,
18 confirms that different Gluten-Reactive and CD
patients recognize an array of gluten and non-gluten antigens. For example, one patient reacts to
omega-gliadin, but not to alpha-gliadin. The second patient reacts to all gliadin peptides, and the
third patient reacts only to the wheat germ agglutinin.
Up to 86 % of patients recognize a different array of peptides.
17 And yet, commercially, the only
peptide that is tested is alpha-gliadin 33 MER. A panel of gluten peptides, which includes a
number of the more common immunodominant antigens, would provide new opportunities to
screen, prevent disease development in individuals at risk,
19 and increase the sensitivity of the test
to identify Gluten-Reactivity (with or without the enteropathy CD).
