In mice, natural killer cells release type II interferon during reovirus infection, which turns on gut dendritic cells to trigger inflammatory T cells that react against food proteins instead of ignoring them.

NK cells contribute to reovirus-induced IFN responses and loss of tolerance to dietary antigen
When mice get infected with a specific virus (T1L), their immune cells called NK cells release a signal (type II interferon) that wakes up other immune cells, causing them to react strongly to food — even when they shouldn’t. The study proves this happens, and if you remove NK cells, the reaction stops.

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 type II interferon signatures in gut lymphoid tissue are consistently associated with dendritic cell activation and Th1 polarization in human celiac disease.
A systematic review and meta-analysis of published studies measuring IFN-γ, CD86/CD8α expression on CD103+ DCs, and Th1 markers in intestinal biopsies from celiac patients versus controls, stratified by reovirus serostatus.
Whether blocking type II interferon signaling during dietary antigen exposure prevents dendritic cell activation and Th1 priming in genetically susceptible individuals.
A double-blind RCT in 120 HLA-DQ2/DQ8-positive infants, randomized to receive anti-IFN-γ antibody or placebo during gluten introduction, with monitoring of CD103+ DC activation markers and Th1/Treg ratios in gut biopsies at 6 months.
Whether NK cell-derived type II interferon precedes dendritic cell activation and Th1 polarization in children developing celiac disease.
A prospective cohort of 600 HLA-DQ2/DQ8-positive infants, with serial blood and stool sampling for NK cell activation, IFN-γ levels, and CD103+ DC phenotypes from birth through gluten introduction, tracking development of autoantibodies over 5 years.
Whether children with celiac disease have higher levels of type II interferon and activated CD103+ dendritic cells compared to healthy controls at time of diagnosis.
A matched case-control study comparing IFN-γ levels and CD103+CD11b– DC activation markers (CD86, CD8α, IL-12p40) in intestinal biopsies from 100 children with newly diagnosed celiac disease and 200 matched controls.
Whether type II interferon levels correlate with dendritic cell activation and Th1 markers in individuals with celiac disease.
A cross-sectional analysis of 200 adults with celiac disease and 200 controls, measuring serum IFN-γ and mucosal CD103+ DC activation markers via flow cytometry and qPCR.
