Research Directions
Various other approaches are being studied that would reduce the need of dieting. All are still under development, and are not expected to be available to the general public for a while.
Using genetically engineered wheat species, or wheat species that have been selectively bred to be minimally immunogenic, may allow the consumption of wheat. This, however, could interfere with the effects that gliadin has on the quality of dough. Alternatively, gluten exposure can be minimised by the ingestion a combination of enzymes (prolyl endopeptidase and a barley glutamine-specific cysteine endopeptidase (EP-B2)) that degrade the putative 33-mer peptide in the duodenum.
Alternative treatments under investigation include the inhibition of zonulin, an endogenous signalling protein linked to increased permeability of the bowel wall and hence increased presentation of gliadin to the immune system, and other modifiers of other well-understood steps in the pathogenesis of coeliac disease, such as the action of HLA-DQ2 or tissue transglutaminase and the MICA/NKG2D interaction that may be involved in the killing of enterocytes.

Famous quotes containing the words research and/or directions:
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
“The cannon thunders ... limbs fly in all directions ... one can hear the groans of victims and the howling of those performing the sacrifice ... it’s Humanity in search of happiness.”
—Charles Baudelaire (1821–1867)
