In people with celiac disease, a bacterial enzyme and a wheat protein stick together, sneak through the gut lining, and end up where immune cells hang out—this might trick the immune system into attacking the gut.

Assessment Explanation
The claim describes a proposed biological mechanism in celiac disease that is biologically plausible and supported by preliminary in vitro and animal studies, but not yet definitively proven in humans. The use of 'potentially' appropriately reflects uncertainty. The mechanism involves co-transport and deposition—complex processes that require direct visualization and molecular tracking, which are challenging in humans. The claim avoids overstatement by not asserting causation, only a plausible pathway.
More Accurate Statement
“Microbial transglutaminase and gliadin peptides may be co-transported across intestinal epithelial cells and deposited in the subepithelial space, where they could be exposed to immune cells in individuals with celiac disease.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
The study says that a food additive (mTG) and a wheat protein (gliadin) stick together and get pulled through the gut lining into the tissue below, where immune cells can see them — which is exactly what the claim says.
