Only one strain of reovirus (T1L), not another similar strain (T3D-RV), triggers a type I interferon-driven immune response in gut lymph nodes that causes the immune system to react to food proteins instead of ignoring them.

NK cells contribute to reovirus-induced IFN responses and loss of tolerance to dietary antigen
A specific virus strain (T1L) makes the mouse immune system react badly to food, but another strain (T3D-RV) doesn’t. This happens because the first virus triggers a special immune signal (type I interferon) that wakes up other immune cells, causing the body to stop accepting food as harmless.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether reovirus strain T1L-specific immune signatures are uniquely associated with celiac disease onset compared to other reovirus strains in human populations.
A systematic review and meta-analysis of studies comparing serological and genomic evidence of reovirus strain T1L versus T3D-RV in children who developed celiac disease versus those who did not, across multiple cohorts.
Whether exposure to reovirus strain T1L, but not T3D-RV, triggers loss of oral tolerance in genetically susceptible infants.
A double-blind RCT in 300 HLA-DQ2/DQ8-positive infants, randomized to receive oral T1L, T3D-RV, or placebo during first gluten exposure, with primary outcome of celiac autoantibody development at 18 months.
Whether children exposed to reovirus strain T1L during gluten introduction are more likely to develop celiac autoimmunity than those exposed to T3D-RV or no reovirus.
A prospective cohort of 1,000 HLA-DQ2/DQ8-positive infants, with monthly stool testing for reovirus strain typing, timed gluten introduction, and monitoring of autoantibodies and immune markers over 5 years.
Whether children with celiac disease have higher rates of prior reovirus strain T1L infection compared to those with T3D-RV or no reovirus exposure.
A matched case-control study comparing reovirus strain-specific serology in 200 children with celiac disease and 400 controls, using archived serum samples collected before diagnosis.
Whether reovirus strain T1L seropositivity correlates with celiac disease status in children.
A cross-sectional analysis of 500 children with celiac disease and 500 controls, measuring serum antibodies specific to T1L versus T3D-RV strains using neutralization assays.
