Le système immunitaire muqueux, et plus particulièrement les réponses intestinales IgA sont essentielles non seulement à la défense contre les agents pathogènes, mais aussi au façonnement de la flore intestinale commensale. Dans les modèles murins de déficit en IgA, on observe une dysbiose intestinale majeure associée à une inflammation muqueuse, réversibles après restauration des IgA. Le but de ce travail est de décrire l'impact de l'absence d'IgA chez l'homme sur la composition du microbiote intestinal ainsi que ses conséquences locales et systémiques. L'étude comparative par analyse métagénomique des selles de 17 sujets déficitaires en IgA et de 34 donneurs sains retrouve l'absence de différence majeure en termes de répartition des phyla...
