While prior work has demonstrated that food allergy can be modulated by gut microbes, little is known about how food allergen-specific CD4+ T cells are affected by gut microbial composition. Here, we report that food allergy severity differs between mice obtained from 2 different specific pathogen-free mouse vendors (Jackson Labs [Jax] and Taconic Biosciences [Tac]). Mice from Tac develop diarrhea and anaphylaxis after fewer allergen exposures than mice from Jax. Using food allergen peptide: MHCII tetramers, we also find that Tac mice have fewer allergen-specific regulatory T cells in the small intestine compared to mice from Jax with concomitant increase in allergen-specific Th2 cells. In addition, Tac mice have increased intestinal permeability. Increased food allergy severity, phenotype of allergen-specific T cells, and increased gut permeability were transferable to Jax animals via co-housing, which corresponded to a shift in Jax microbial communities towards those found in Tac mice. Our findings demonstrate that food allergen-specific Treg cells can be modulated by gut microbial community composition, which in turn is correlated to food allergy severity.<\/jats:p>","DOI":"10.1093\/jimmun\/vkag172","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T04:02:34Z","timestamp":1785470554000},"source":"Crossref","is-referenced-by-count":0,"title":["Gut
