Trafficking of IgA/commensal complex in the gut has been implicated in inflammatory bowel diseases such as Crohn’s disease, but molecular insights are still lacking. Here the authors show, using mouse model or human cells, that NOD2 mutation increases IgA transport, potentially by altering gut microfold cells from the gut, to impact gut inflammation.
