Microbial metabolism of food allergens determines the severity of IgE-mediated anaphylaxis

Elisa Sánchez‐Martínez, Liam Emile Rondeau, Manuel Garrido‐Romero, Bruna Barbosa da Luz, Dominic A. Haas, Gavin Yuen, Dana Coppens, Peter Hall, Rebecca Dang, Xuan-Yu Wang, Lucía Moreno‐Serna, Celia López‐Sanz, Emilio Nuñez‐Borque, María Garrido‐Arandia, Araceli Díaz‐Perales, , Alberto Caminero

This study shows that gut and oral bacteria metabolize peanut allergens, affecting IgE-binding and anaphylaxis severity in allergic individuals.

Dietary tryptophan enhances aryl hydrocarbon receptor activation and reduces colitis through microbial metabolism

Liam Emile Rondeau, B Barbosa da Luz, Dominic A. Haas, Pranshu Muppidi, Xuanyu Wang, Rebecca Dang, Gaston H. Rueda, Andrea Nardelli, Giada De Palma, Harry Sokol, Přemysl Berčík, Alberto Caminero

This study shows dietary tryptophan improves AhR activation and reduces colitis by enhancing microbial tryptophan metabolism in preclinical models.

Antibiotic use in early life subsequently impairs MAIT cell-mediated immunity

Gabrielle LeBlanc, Adam L. Sobel, Jonathan Melamed, Dominic A. Haas, Eduard Ansaldo, Aiko M. Cirone, Elizabeth Murguia, Michael G. Constantinides

This study shows that early-life antibiotic use reduces MAIT cell abundance, impairing immunity to pneumonia, but this effect can be reversed by reintroducing riboflavin-synthesizing commensals.

MAIT cell responses to intracellular and extracellular pathogens are mediated by distinct antigen presenting cells

Dominic A. Haas, Jonathan Melamed, Gabrielle LeBlanc, Nikhita Arun, Andrew J. Perkowski, Jeffrey Aubé, Matthias Mack, Michael G. Constantinides

This study shows that MAIT cells respond to extracellular and intracellular pathogens via distinct antigen-presenting cells, with type-17 MAIT cells responding to Acinetobacter baumannii and type-1 MAIT cells to Francisella tularensis.
